Sunshine! - Official Thread

Hello,

Orthographic cameras should work fine, I just ran a quick test and shadows+scatter looked correct.

Cheers,
Oren

 

Hey Poly Vector, thanks, I made the purchase. I'm having some troubles on a light study I'm setting up.

1 - I have my orthographic camera set up below. However, I'm trying to restrict the light coming into the room. When have cast shadows set to two-sided, it doesn't seem to be blocking the light. What I had to do is create two large planes and face them the opposite direction to block it, yet that's imprecise, and the planes are showing up. How do I avoid this?




2 - I tried getting the shadows on my little cube there working, but it's not. It works on my point light farther in the scene, but not there. Here's my settings

My setting under Player Settings is Forward Rendering Path with a Linear Color Space
I have a light probe group
The Directional light is set to mixed lighting (to try and get the shadows) and the Point light is set to Realtime to get the shadow
The cubes (big and small) are set to Sunshine/Standard shaders because it is a forward lighting situation.

I installed forward shaders since my rendering path is forward.

3 - When you saw avoid image effects, is that for mobile optimizations only? Do you consider Scion Filimic Post-Processing image effects?

4 - How could I get the animate dither effect to be more pronounced at a zoomed out orthographic look to get give the illusion of dust.

Thanks!

 

Hello,
I'll try to answer to the best of my ability.

1. Sunshine doesn't use the "Cast Shadows" setting, so you'll have to make an adjustment to "Sunshine Occluder.shader". You'll want to add "Cull Off" to the "Opaque" RenderType subshader.

Code (csharp):

1.  
2. Tags { "RenderType" = "Opaque" }
3.        Pass
4.             {
5.                   //Add the following line:
6.                   Cull Off
7.  

2. Here are some ideas. With orthographic cameras, sometimes the camera is placed too far away (but doesn't appear so without perspective). You may need to increase the "Light Distance", or define a "Custom Bounds" Transform which is located under "Advanced Settings". I would try setting the Directional light to "Realtime" just to be sure.

3. This was only meant as general advice, and was written some time ago... Devices are pretty powerful these days. I don't have experience with the Scion shaders.

4. The dithering isn't really meant to get a dust effect. You could theoretically modify the Scatter shader to blend with a smoke/dust texture to give a complex look.

I hope this helps.

Cheers,
Oren

 

Hello,

Is your extension compatible with Unity 5.5 ? How you advanced shadow system manage fading transparency in standard shaders ?

Regards,

hlx

 

It appears to work in Unity 5.5, and I haven't received any new reports of problems. When new compatibility issues spring up I try to be quick to remedy them.

Transparent objects normally receive shadows and cast them as if they were Cutouts, but this doesn't appear to be happening in Unity 5.5, hmmm. I'll have to investigate this further.

Blending transparent objects with Scatter either happens on top of or behind the scatter depending on the effect order, there isn't currently a good way to blend in the middle. It's similar to Unity's "Global Fog" in that respect.

Cheers,
Oren

 

Hi Oren, I'm considering purchasing this but would like to know it's fully working on Unity 5.5.

From the above post you say it "appears to work" but then go on to say that the transparent objects "don't appear to be happening" ? Could you please confirm if this Asset is fully working on Unity 5.5 ?

 

Hello radimoto,
Sorry about the confusion, I only had a few minutes on Friday and was confused when the shadows didn't appear to be received in a quick test project I threw together. I had accidentally only enabled the volumetric scatter and not the custom shadows, so that meant I was seeing Unity's built-in shadows. Silly mistake.

I tested again this morning and everything appears to be working in both 5.4.1 (the current submitted version) and 5.5.0 when upgraded.

Both the included replacements for Legacy Transparent Diffuse and the Standard shader (set to Fade) work just fine on my machine.

Thanks for your patience.

Cheers,
Oren

 

hi, is Atmospheric Scattering same thing as sunshine?

 

Hi,
Not exactly. Sunshine has a form of "volumetric scattering" which is uniform, whereas atmospheric scattering algorithms tend to adjust the color/effect based on the horizon/sun. There are some atmospheric scattering packages on the asset store, but Sunshine is more "vanilla".

Cheers,
Oren

 

Hi Oren,

we are considering buying Sunshine for our next VR game (Vive). We are mainly interested in good-looking (as in non-blurry, non-blocky) dyanmic/realtime shadows from the hands and stuff which is in the hands. "The Lab Renderer" worked for us before, but has limitations on the amount of lights, and doesn't seem to play nicely with Unity 5.6 beta.

So, my questions. First, am I correct in assuming that shadows are supported for all light types (not only directional) and they all look similarly good (I ask because Unity's shadows differ quite a lot between directional and point)? Second, will you update Sunshine for the changes in Unity 5.6 (the major lighting overhaul)? And third, is it ok to test the plug-in and ask for a refund if we find it doesn't fit our needs?

Thanks!

 

Hello,
Sunshine is designed primarily to provide volumetric scattering for a single Directional Light, no other lights are supported. The shadows have some interesting features like overcast (cloud) shadows, and a runtime baking-like feature, but they aren't going to be smoother than the PCF 5x5 that's been built-in since Unity 5.

We will be updating for 5.6 when it is finalized, and of course, you may test out the plugin and ask for a refund if it doesn't work out. Honestly though, it doesn't sound like it's a good given what you're looking for.

I hope this helps.

Cheers,
Oren

 

Hi Oren, thanks very much for your honest answer, I really appreciate it! Based on your experience, do you know of any Unity assets (besides "The Lab Renderer") that might have the feature set I am looking for? Thanks!

 

I'm not aware of many shadow modifying projects out there. I have Shadow Softener, but this is merely attempting to perform a higher-kernel PCF blur, so it's "more blurry". You could see if anyone has done a PCSS implementation, which is where the shadow kernel depends on the distance from the occluder.

Sorry to not be much help, I've been working on very minimalist games lately and haven't been looking for any fancy assets myself.

Cheers,
Oren

 

I'll do some lookups on PCSS then. Thanks again!

 

Quick question, does Sunshine take advantage of the feature in Unity 5.5 which uses a reverse depth buffer to improve shadow precision?

 

No, Sunshine is completely separate from the built-in shadows and uses it's own depth format packed into a an RGBA32 buffer.

Cheers,
Oren

 

I apologize if this has been asked before, but how to get Sunshine in Scene View?

1. #if UNITY_5_4_OR_NEWER
2. [ImageEffectAllowedInSceneView]
3. #endif

 

I don't believe it works in sceneview due to the way it's designed. It's something I'll look into for an update though.

 

Not sure if this has been asked but does anyone know if Sunshine works correctly with the current VR setups in Vive?

Also does this work using unity's directional lightmapping setup with a directional light set to Mixed mode. You can bake a unity terrain with a bunch of speed trees using Mixed mode directional lightmapping and the speed trees will bake shadows into the terrain and still cast real-time shadows on themselves and ground based on shadow distance. So before I make a purchase just wanted to make sure Sunshine supports these current setups. Thanks.

 

Yes, I can confirm Sunshine works very well out-of-the-box with Vive in forward and deferred paths (although for VR better to stick with forward) (Unity 5.4.1f1-3)

 

Hi PolyVector,
I am using Unity 4.6.5f1 and i still get the error :

sunshine.cs(140,65) error CS1061 Type UnityEngine.Light does not contain a definetion for shadowNormalBias and no extension method of shadowNormalBias of type UnityEngine.Light could be found

:/

 

Hi Marcell,

It sound like you're using a new version of Sunshine with an old version of Unity. The Asset Store should have served up an older copy of Sunshine, so that's strange.

If you navigate to Sunshine using the Asset Store tab there should be an "Update" button that will actually downgrade Sunshine to a compatible version. I just tested this with Unity 4.6.5 and it works fine.

Cheers,
Oren

 

Hello,

Unity 5.5.1 official build does not work with Sunshine in deferred. They have changed quite a lot with deferred rendering, and I had to find some workarounds for my wrapped diffuse lighting too.

It's the internal deferred shading replacement -in unity 5.5.1 it's done in 2 passes, but sunshine does everything in one.

I've got the newest available version of sunshine, downloaded today, using deferred, win 10 64-bit, dx11.

Is there a newer version or a fix I can receive?

 

Just downloaded 5.5.1 to test, and I didn't see a problem on my Mac, although I don't have a DX11 setup. Make sure you have Sunshine-DeferredShading selected in the Graphics settings in your project.

If you still have trouble, try right-clicking and re-importing any shaders throwing errors, I've seen Sunshine import incorrectly the first time.

Cheers,
Oren

 

Seems to be a problem in 5.5.1

Several other workstations had problems simultaneously on upgrade.

We downgraded to 5.5.0 and everything works fine.

Yes. I checked .

 

Thanks for the info. I'll dig into what changed between these two versions and see if I can come up with a fix for you.

Cheers,
Oren

 

Hi, I'm possibly interested in trying Sunshine in my VR game. It's an extremely large map. My camera right now has a view distance of about 45k (and surprisingly the latest version of Unity works well with that). I want to push a shadow distance of at least 3000, preferably up to 10,000. Unity shadows of course glitch out at this distance. I'm ok with lower resolution shadows, as long as they're stable.

tl:dr
Does sunshine handle distance better than the Unity shadows?

 

Thanks PolyVector, the updated shader for internal deferred does work in 5.5.0

 

Yes. Slightly better. I found with Sunshine I can stretch shadows out to about 300 meters. In Unity, even after hours fiddling with cascades, the shadows look pretty bad after 150 meters. Also, because sunshine can occlude layers per cascade, there's less calculation, less overhead, for those very long ranges.


HOWEVER...

I am having quite a time trying to figure out how to make my custom shader with animation cast animated shadows with sunshine. There is no such example to follow, so I'm still working out what's possible.

 

How does piggybacking my vertex animation work. Can you please provide a corrected example? The manual is very non-explicit about this. Take my example above: How do I "piggyback" the vertex shader to get the correct shadows?

NOTE: I'm talking about the "v.vertex.xyz -= float3(sin(_Time.z),0,0);" animation

 

Awesome, thanks for the info. Also, do the cloud/overcast shadows show over an infinite distance (like if you put a tiled cookie on a directional light)? Or do the cloud/overcast shadows only show up for the same distance as the regular shadows?

 

Your Example:
Your example doesn't really need piggybacking, that's mostly intended for vertex shaders you don't have control over (ie. in an include file). All you really need to do is add this line to the end of your vert() function:

Code (csharp):

1. SUNSHINE_WRITE_SURF_VERTEX(v, o);

Piggybacking Vertex Shaders:
If you did want to use piggybacking, you would instead change the SUNSHINE_SURFACE_VERT(Input) line to:

Code (csharp):

1. SUNSHINE_SURFACE_VERT_PIGGYBACK(Input,vert)

This would generate the sunshine_surf_vert function() in a way that also uses your vert() code.

Simplest Alternative:
Alternatively you can tell Sunshine to work exclusively in the pixel shader, this can be a good option for complex shaders or when you're stumped. You can do this by adding this line before including Sunshine.

Code (csharp):

1. #define SUNSHINE_PUREPIXEL

Once you do this, you can leave out all vertex-related Sunshine code (No more SUNSHINE_INPUT_PARAMS, or SUNSHINE_XX_VERT).

Casting Shadows:
The above techniques deal with shaders recieving shadows, not casting them. If you need a custom vertex animated shader to cast shadows, there is some additional work required:

1. Use a custom RenderType for the shader, ie. "OpaqueAnimated".
2. Create a new SubShader in Sunshine Occluder.shader using that RenderType.
   
3. perform your vertex modifications there.

It's a little roundabout, but there's currently no other way in Unity to accomplish this.

I hope this helps,
Oren

 

Projected Overcast Shadows should work over an infinite distance.

Cheers,
Oren

 

Exactly what I was looking for!

 

I just got Sunshine and I'm liking it so far. One problem though, in my main game, the volumetric light scattering jitters in VR. I checked the sample scene and made a new scene and both didn't jitter. It's only my main game that jitters. Any idea on how to fix this?

 

I fixed my own problem. The volumetric light scattering was shaking because my main camera's near clip plane was too small. I had it set to 0.03. I set it to 0.2, now it works fantastic! The lighting looks so amazing. Thank you for this asset!

 

Hi We just bought sunshine and it looks terrific. I've noticed 2 posts on shaderforge and Sunshine but no examples.
I must admit being a crack at shaderforge but a horrible mess at actual shadercode.

I've tried to integrate your codesample into the shaderforge code, but its not giving any output.

would you mind changing this example, so everyone who uses shaderforge has an example where you change and edit the code for sunshine to work.
Sorry for not being able to fix it myself..
Here's a shader as exported from shaderforge:

I'd love to have this working with the mobile sunshine shadercode.

Sunshine 1.8.6 is Now Available in the Asset Store

• Unity 5.6.0 Support
  
• Upgraded Standard/Legacy shaders

 

Hi,

Is it possible to get a download from you guys directly for the 1.8.6 update? We're updating our version in our project but when we download 1.8.6 from the Asset Store tab in Unity, the Unity diff tool shows that nothing is actually changed, and in sunshine.cs it still says public const string Version = "1.8.5". This also happens if I simply create a new Unity project, and only import Sunshine. The asset store tab says 1.8.6 is downloaded, but the code is identical to the 1.8.5 version we have on our source control repo. We need the update as we're trying to update to Unity 5.6. Thanks!

 

Hello,
Make sure you're running Unity 5.6.0f2 or above (I believe the final release was 5.6.0f3). I just tested with a blank project and Sunshine 1.8.6 updated/imported correctly.

Cheers,
Oren

 

Thanks! That did it. Another question:

Does Sunshine support shadows in single pass rendering for VR? We're working on a VR game and the shadows in both eyes don't match up properly.

 

I also would like support for single pass rendering on GearVR to be exact, but i think its the same as all VR platforms.

 

Sorry, I don't believe Sunshine works with single-pass VR rendering. It has been used successfully in VR in one form or another though. Sorry for the vague answer, I don't have a lot of VR expertise.

Cheers,
Oren

 

Hi,

I have recently noticed that enabling shadow cascades doesn't produce correct shadows in Unity 5.6.1p2 (Windows platform DX11 forward rendering) and Sunshine 1.8.6. They worked fine in Unity 5.5.x and I'm unsure what 5.6.x version of Unity they broke in (it might have worked in 5.6.0 but I can't remember). When I turn off cascades, the shadows work fine.

I was able to reproduce this problem in an empty Unity project with just Sunshine imported and a simple test scene and if you wish I can send you a copy of the project.

Thanks.

 

Hey RV1,

I've been running some experiments and narrowed it down to regressing between Unity 5.6.0 and 5.6.1. Unfortunately it appears to be just about the strangest Unity bug I've seen yet, and I can't even begin to rationalize the behavior I'm seeing Unity exhibit in the Frame Debugger.

What I'm seeing is Unity 5.6.1 drastically changes the way cameras render to RenderTextures.

1. A Camera renders to a RenderTexture using a smaller Viewport by adjusting the Camera.rect
2. Unity allocates a separate Temporary RenderTexture and uses that instead with a Full Viewport.
   
3. It then blits the smaller RenderTexture back to the original RenderTexture incorrectly overwriting the entire thing.
   
4. The previous step is marked as Resolving AA... Despite MSAA not being used.

Steps 2 through 4 are wastefull, inefficient, buggy, and nonsensical. I can't imagine that this behavior is on purpose, my best guess is that it's the result of them focusing on VR to the detriment of everything else.

I'm not sure this one can be worked around, and the performance is being harmed even with a single cascade. Sorry for the inconvenience, I'll be submitting a bug report with Unity today.

 

Thanks so much for taking time to look at this. Totally not your fault as sadly Unity 5.6.x has broken many things

 

Thanks for your understanding, here's a link to the bug report I've submitted: https://fogbugz.unity3d.com/default.asp?918751_v2hg36b6kebo578f

 

I am unable to get Sunshine custom shadow mapping on a terrain using RTP shaders in the forward path. Is this a known issue? I'm fairly certain the issue is related to the fact that the shader or material instance RTP is using in the terrain engine is not being modified by Sunshine's forward shader installation process.
