► DirectX 11 Low Poly Shader ◄

Wireframe effect is enabled per-shader. All meshes using that shader will be effected.
You can just reduce wireframe color A value and it will become completely invisible.
Or copy shader file (rename file and shader name inside file) and enable wireframe effect on it.

There is no such control as 'size of low poly'. Mesh completely becomes faceted.

Hi,

Can you please add Emission map (texture,color and intensity)?

Thanks you in advance.

 

Added to a wishlist.

Hi, i have a procedurally generated terrain made of different planes and the i aplly some textures on it based on the Y value, will this shader make the terrain low poly? can i apply this via script at runtime?

 

This shader will not reduce triangle count, if it is what you are asking. Shader will just render mesh in lowpoly style.

Is there any chance you could ever get this on unreal engine? Or maybe walk an unreal dev like myself through the process?

 

I'm sure there already is a DX11 shader like that for Unreal. It's not a Unity feature but a custom shader he did.

 

Headache I have with Unity is enough, thanks.

Hi,

What is the process of adding the Shader to terrain, is their documentation I can read about the Low Poly shader.

I have enjoyed this Asset, and have been having fun changing my models to low poly, but need to get my terrain and skybox to show in low poly?

Thanks

 

Or you can just use Unity?!

 

Look at this quote here:

I'm not sure if you can apply the shader to skyboxes though. Note:If the colour of the terrain is wrong after adding the terrain material you need to save the scene and the colours should be applied correctly.

 

@Arkhivrag I would just like to say that it would be nice if you added support for multi-tile terrains (multiple terrains that is used to represent one). You can clearly see the difference between the terrain edges. I would personally pay twice the price just to get that Great asset by the way, it improved the performance of my game substantially.

 

Potential buyer here, would this work with the voxel terrain engine, Voxeland?

 

If custom shaders can be used within Voxeland then YES.

I'm using the Low Poly Mesh Generator and am liking it, curious if I should switch over to this. Looks to be a lot more efficient. I don't understand how you're getting the memory usage so low, are textures/materials dumped out of memory after they're sampled?

Your link to the Geometry Shaders test is broken. I'm assuming this should work on most popular platforms and consoles?

 

You can switch to DirectX 11 Low Poly shader if your project is for devices with GeometryShader support.
Link fixed.

Hi Arkhivrag,

I think I have a pretty good idea of how this works but you probably don't want to get into super technical detail about it. I do have two questions though:

1. How does this compare to using DDX/DDY to compute a flat normal, in terms of performance and quality?
2. Any plans to support the full range of options / shader math in the Unity standard shader?

The issue with Geometry shaders in general is that since they don't support surface shaders making them use the same lighting math as the Standard shader is fairly difficult.

In theory it's possible for a vertex/pixel shader to still call UNITY_BRDF_PBS with the right params, do shadow coord stuff, etc, and come out looking the same as the standard shader. Any plans to support this?

 

You can not achieve same quality with DDX/DDY to compute a flat normal. Geometry shader pass is necessary to re-create new normals and calculate per-vertex color (+ new tangent, shadow coords etc.)
Shaders use the same lighting math as Standard shader.

Hey there!

So are you saying that if I save my FBX as "smooth" shading in blender, it will turn it to flat shading in Unity?!

I can't get the image to display here but here's a link to what i mean:
https://imgur.com/a/KKQVT

This is the EXACT same tree, with Flat vs Smooth shading. Would your shader make my smooth tree look exactly like the flat tree, but with the smooth tree's vert count?!

 

Darn was hoping for a reply by now, really wanna try it out!

 

Yes!



VacuumShaders - Facebook Twitter YouTube

 

Ok, wow.. so that should save me about a million verts. Amazing.

I think it's so ironic that Low Poly is High Vert

 

Really cool product- loving it so far. I have a question though: Is there any way to "bake"/export the texture/material as a standard material/shader once you have a look you like?

I am getting some errors when I try to export a WebGL build like:

"Error building Player: Shader error in 'Hidden/VacuumShaders/DirectX 11 Low Poly/ZWrite': '[' : syntax error syntax error at Shader/Shaders/cginc/Geometry.cginc(33) (on gles)"

If theres a way I can export the lowpoly into a standard material? I think it would be a lot easier on processing power and won't cause errors when I try to make a build

 

WebGL currently does not support GeometryShaders.

Ah ok that's why.
I was attempting to do a webGL build and it seems to have broken the entire shader... Guess I will have to reserve the lowpoly version for only desktop and mobile!

Do you know if theres any way to "bake" the texture/material out to a standard or built in unity shader like Toon? I love the look of your shaders but I'd really like to make my builds have a little dependency on 3rd party plugins as possible. Your shader seems pretty complicated so I know it's a longshot, but just wondering!

 

I'm interested in buying this asset for a single reason; That being, that Unity's built in Cloth component doesn't allow flat shading for its meshes. Would This shader be a way around that, or do cloths still shade smooth with it on?

 

There is no way to 'bake', but you are free to modify shaders.

Cloth component needs SkinnedMeshRenderer and this shader can be used with it.

I just discovered this vertex count problem in my current project and your shader would be the perfect solution. Is this Shader still available for Unity 5.6.1? If Yes, where can I find it?

 

Will definitely work with Unity 5.6.4



VacuumShaders - Facebook Twitter YouTube

 

so this shader would replace the ones in the mesh materialiser pack?

 

Hi @Arkhivrag, we've been using these shaders on a game we're working on, and we were seeing much better vertex counts while keeping the flat look we're looking for, so it's been great!
However, we are now testing these on the newer versions of Unity (2017.2.1p2)., and on consoles we're getting errors when trying to build the game (the build fails showing the same error for multiple shaders). Previously on 5.6.2p2 we didn't see these, we could build the game successfully.

I'm adding more details on a DM.

Do you know what could be causing these?

Edit: OK, the fix was just adding an "else return 0;" statement in the function from the error. Thanks for the help!

 

Hi @Arkhivrag, I just wanted to know if it would be possible to add Rim Light to these shaders, as it would be another nice extra feature to have. We also use your Subsurface Scattering Shader, and we have seen that those have the option on them. Having it implemented on the Low Poly ones would be good for us, since we sometimes use it to simulate extra colored 'reflections' on some environment meshes.

Just to see if it was possible, I've tried to add it to the 'PBS_Opaque_Diffuse', adding the rim calculation into the Emission. I'm still new to shaders, and the DX11 Low Poly is more complex than what I'm used to, so I don't know if this could break other things or not.

Code (CSharp):

1. ...
2. [VacuumShadersLabel] _RIMLIGHT_LABEL("Rim Light", float) = 0
3. _RimColor ("Rim Color", color) = (1, 1, 1, 1)
4. _RimPower ("Rim Power", Range(0.01, 10)) = 1
5. _RimIntensity ("Rim Intensity", Range(0, 10)) = 1
6. ...
7.  
8. // And this both on the Forward Base and Deferred passes (around lines 250 and 620):
9.  
10. fixed4 _RimColor;
11. fixed _RimPower;
12. fixed _RimIntensity;
13.  
14. //DirectX 11 Low Poly////////////////////////////////////////////////////////////
15. // Rim
16. fixed NdV = dot(IN.worldNormal, worldViewDir);
17. fixed rim = _RimIntensity* pow(1.0 - saturate(NdV), _RimPower) * _RimColor.rgb;
18. ...
19. o.Emission = (...) + rim;
20. //////////////////////////////////////////////////////////////////////////////////////////////////
21.  

The result:


Is what I'm doing correct? Right now it appears to achieve the effect I was looking for for this specific shader.

Also, would it be possible to achieve the faceted look for the rim light on all lighting modes? I've seen that the lighting can only be "low poly" on Forward and not on Deferred, but I don't know if it would be possible to add the RimLight before calculating the "lowpoly" color/emission (if I'm not mistaken, right now I'm adding the rim light after this calculation has been done).

If this could be 'officially' added to the collection of shaders I think it would be great! (Another interesting idea that came to mind would be to also have transparent objects that still have a full rim light, in order to simulate crystals or force shields for example).

Thanks!

 

Tom, I am struggling with the same problem (adding the shader to water + animating the water with waves). Could you give me more details on how you achieved this?
Thanks a lot!

 

I am having trouble getting the shaders working. I cant get a successful build. Using Unity 2017.3.0f3. Is this version not yet supported?

Errors for windows build: Shows the 3 Test Shaders (4.0, 4.6, 5.0) Green in Tester Scene

Errors For Android Build: Device Shows the 3 Test Shaders (4.0, 4.6, 5.0) When Using The Test Shaders.

Any help would be appreciated.
Thanks

 

Hi there,

I have exactly the same problem with unity 2017.3.1p2, is there any solution for this?
As we are trying to build our game here, any help would be much appreciated.

Cheers,
Simon

 

Sorry, I was unsubscribed from this thread (do not know why) and did not receive notifications about activate here.
Unity 2017.3 shader compilation bugs are fixed, just download new version from the Asset Store.

@Arkhivrag Could you add a triplanar shader ?

It's for use in a voxel engine, on one single material I want to use a texture or color for X-Z oriented geometry and another texture or color for Y oriented geometry. For example, green for grass and grey for rock.

And another less precise request : do you think you could do something to get procedural color gradients like in the game cubeworld ?

 

Added to a wish-list.

I'm building a scene for standalone MacOS X using this shader. It works just fine when I play the scene in Unity Editor, but when I build for mac, the shader doesn't work at all. Are there settings that I should check before building? Please let me know.

 

Do this test shaders work?

Is this compatible with Unity 2018.1? Also would Voxel models made in MagicaVoxel work with this (see attached image)? Since I cannot find a suitable terrain to voxel converter (blocky like MineCraft but uses smaller cubes), I plan to just convert Voxel models to have that low poly faceted look instead so it would be consistent. But not sure how it would look. What would be more ideal to use, the DirectX 11 Low Poly Shader or your Low Poly Mesh Generator?

 

Low Poly Mesh Generator bakes texture directly into a mesh, has limit on mesh vertex count (max allowed is 21000), but works on any device with any shader supporting vertex color.
DirectX 11 Low Poly Shader requres device with Geometry Shaders support (mostly not available on mobiles).

It looks like DirectX 11 Low Poly Shader will work best for me. But the main thing still bugging me is whether the produced effect will be that noticeable for my type of blocky models. I am currently deciding whether to either use this tool for all my models and terrain to have a consistent low poly look -or- just stick with mixing blocky models with an ordinary terrain look if I cannot find a suitable tool. Have you tried using this with blocky type models? Do you have a sample screenshot of the result?

Sorry for all the trouble but I have already been burned with buying another tool by a different developer which claimed to convert models and terrains to blocky style instead. But that didn't work and I now cannot seem to reach the developer anymore to get a refund. Thus I have to be a little careful now.

 

Send me one of your blocky models with textures. I'll show you how it will look using DirectX 11 Low Poly Shader.

Alright, sent the 617KB ZIP file to your Vacuumshaders Gmail address.

Edit: By the way, sent you another ZIP file w/ a .DAE updated model for the boat that has some glass transparency, emission, and metallic shaders. Are these supported? Can you use this as test?

 

@Arkhivrag hi, I love your shaders, but I want make it work with vertex animation, Houdini offered a couple of vertex animation shader(fluids, fragments, cloth), but I don't know how to combine them to your shader , I thought just need to put houdini vertex shader vert function before your vert function, but it didn't work, my shader scripting sucks... could you give me a hint about how to modify.

 

Hi, will this work well within a 2d game (using sprites)? Thanks.

 

No.

I want to apply this to a webcam texture to give the webcam feed a low poly effect. Is this supported? If not can I contract you to add that support?

 

@WelchCompositions My guess is no, as this is a shader attached to the mesh and makes the light hitting the 3D mesh look as it does. A webcam texture is just that, a 2D texture. There are no normals with light information.
