TENKOKU - Dynamic Sky

TENKOKU - Dynamic Sky System for Unity 5
Tenkoku – Dynamic Sky brings completely dynamic high-fidelity sky rendering to Unity developers. There are no sky boxes or static elements, everything from the clouds to each individual star is it's own individual element with appropriate movement and behavior.

I bought this from your website. I find setting it up to be a bit difficult. Can you create a 'setup' scene for Unity 5, or a demo scene?

 

Hi Exeneva, Thank you for your purchase! A demo scene is coming soon. In the meantime below is a step-by-step instruction guide for installing... take a look and let me know if anything is unclear. Also if you continue to have any difficulty, or have sky that looks weird in any way then please send me a screenshot and we'll get it worked out together.

(Edit 2016... the below image shows a completely outdated install procedure)

 

Can you please also describe how to set the unity 5 lighting settings ?

 

Unity 5 lighting... pertaining to what?

 

Camera flags. Also which component goes into the sun setting in environmental lighting under scene lighting in lighting tab.
Thanks

 

Do we leave skybox blank - or default or something else ? Reason i ask is when i tried in scene - was unable to get the terrain to light nicely even though the sky was gorgeous.

 

@AdamGoodrich the Skybox should get overwritten in the scene when Tenkoku is turned on... so it may be best to leave this set to color instead of skybox (on your camera object I mean). In order to get the Tenkoku sky info feeding into Unity 5 shaders you'll need to add a Reflection Probe to your scene with the following settings...



Note the "Size" setting needs to be large enough to encompass the geometry in your scene... and it should possibly(?) be made a child of your main camera object. Actually I should probably have this setup for you guys automatically. I'll look into this for the next update.

Also note that if you have additional lights in your scene you should remove the "sky" layer from their culling mask setting, otherwise it's likely to blow out the sky rendering colors.

For the camera in your scene make sure it's set to render the "sky" and "moon" layer.
The "sun" setting in the Unity Lighting/environment section can be left blank as this is only meant for built-in unity 5 skyboxes. Tenkoku renders it's own skysphere, so this isn't needed.

 

And I've found the first post-release bug... the nighttime star/galaxy is not rendering properly when a project is in gamma mode. Changing to "Linear" mode fixes this (and indeed I recommend running in linear for best rendering fidelity anyway). I'll have this fixed so they work in gamma in the next update.

 

Thanks much appreciated - will see how i go with it

 

Hmm... my scene looks fine when its running - but is unusable in edit mode. Here is a little test i created - its using linear lighting, and static flag has been removed from terrain so that its all real time lit.

 

And the last image...

 

Must say i to really like it tho - so my issue is more with how to use it in edit mode

 

Does Tenkoku work with the Oculus Rift DK2? Is it intended to work in combination with Suimono?

 

@MS80 I haven't tested the rift personally, but I've had reports of it working just fine from some customers. It currently works well together with Suimono, but Suimono will require the 2.1 update (coming soon) for a more full integration.

@AdamGoodrich I'm sure I could make some changes specifically for edit mode so it doesn't black out your screen... right now I believe it doesn't do anything in edit mode, so the lights and colors aren't calculated until you hit play. This is likely the root of the problem.

 

@AdamGoodrich That terrain is badass by the way

 

I'm working on a project which I plan to use a custom 80 day calendar (4 seasons, 20 days each) and have 2 moons. Could Tenkoku be used for this?

 

Any way this would be ready before this weekend? Ludum dare 32 is taking place this weekend.

 

@NunSuperior The timings and movement in Tenkoku are calculated for earth (and are pretty complex) so changing them in order to get a shorter season isn't feasible at the moment, unfortunately. A second moon could be added but you would have to dig into the code to do so. Alternatively you could turn off the tenkoku movements, but you'd have to code your own 20-day seasonal movements... I don't recommend this.

@Exeneva I'll try and get a small update version out by Friday

 

So how does the day / night cycle work then?
I saw an option to "speed up" day / night, and adjust a curve to make night even shorter etc. But if we have a day night cycle set to say 6 hours, that would mean 4 game days per real day. What happens to the DATE variable then? I assume it rolls on to next day after each game cycle? ie. what changes the date value if not a game day/time cycle?

 

Yes that's correct... the actual passage of time can be sped up or slowed down based on an auto-time multiplier, and yes you can change the curve over a 24 hour period to speed up the passage of time at night for example. once the hour hits 24 it resets to the next consecutive day... once the day hits 365.25 it resets to the next year... etc.

However the actual length of the moon/month cycle and thus the length of seasons/year are calculated based on earth-centric data so a typical month will have around 30 days in it, and this isn't currently editable very easily. So you can control how fast hours/days/months will pass, but you can't really control how many days in a month or how many days in a year etc.

 

Thanks for the quick reply.

 

working on integrating Tenkoku with Sunshine:

 

@mittense Oooooh cooool

Just as an FYI, for anyone using Tenkoku in Unity gamma mode I've just fixed a number of lighting/rendering bugs. A new update should be ready in the next day or so.

Hi,
Love the atmospherics, but have an issue with SpeedTree and the atmospherics and fog.
I deliberately made it worse so you could see it in the attached picture... seems like speed tree not being affected by it... Hope you can fix that as its the only thing bringing down a totally awesome asset!!
Also, fyi, I set up Tenkoku to use Sky layer and got no light on my terrain (in the terrain layer). But then when i set back to default it worked fine. I have no idea why
Cheers,
Adam.

 

Hi Adam,

Hmm... I've had no trouble with Speedtree trees here on my end... the demo video above is using speedtree. I wonder if some models have this issue and some don't? Are your trees populated via the terrain system, or are they placed by hand or instantiated with code?

 

Hi Chingwa,

The trees were manually placed using the standard terrain tree tool i.e. they are not separate objects.

Actually i found something else that might point you in the right direction- you can also see that the rock is not being handled properly regardless of whether it is static or non static. The terrain is being done via RTP. The rocks on the hills are rocks out of an asset pack.

The issue here is that fog is not affecting anything but the underlying unity terrain.

Your lighting is gorgeous so I hope you can find a fix

Cheers,
Adam.

 

Here is an example that shows distant objects being affected by fog / haze.

 

This seems like a real mystery! I've tried a few tests here using different types of objects/shaders and can't seem to reproduce this. I've tried legacy shaders as well as U5 standard shaders to no avail. I only have a couple different speed tree models here, but I've tried all the ones I have and they work ok.

Do you have a multiple camera setup in your scene? Does RTP change the SpeedTree shaders in anyway(that you know of)? Perhaps it's possible to export a couple of your scene objects (maybe 1 rock model and 1 speedtree model) and send them to me for testing?

 

Thanks Chingwa - Have been pushing some crazy hours over past few weeks to get thru this project on time. Delivered yesty. Will create a test project and send thru in the next week - the one i have is too large. I am sure it is a simple thing to sort out. Cheers Adam.

 

Sounds good Adam! If you prefer to email directly you can reach me here... konnichiwa[at]tanukidigital.com

Hi Justin,
Have sent you a link to a shared directory along with a rar file with a reproducible test.
Cheers,
Adam.

 

I am working on a multiplayer game and the player is spawned so I can't set the camera in the editor. Can I set the scene camera at runtime?

Thanks,

Andy

 

Hi Andy,
Well first, if you don't specify a camera it will search your scene for a camera tagged as "MainCamera".
If you need to instead specify the camera while running your scene you can do this...I've made a few edits to the main code thread which will make this a bit smoother. I just sent you an update via email. With the code update installed all you have to do is place the below code somewhere in your scene, and it will set tenkoku to use whatever camera you specify as "Use Camera"...

Code (CSharp):

1. #pragma strict
2.  
3. var useCamera : Transform;
4. private var tenkokuModule : TenkokuModule;
5.  
6. function Start () {
7.     tenkokuModule = GameObject.Find("Tenkoku DynamicSky").GetComponent(TenkokuModule) as TenkokuModule;
8. }
9.  
10. function LateUpdate () {
11.     if (tenkokuModule != null){
12.         if (useCamera != null){
13.             tenkokuModule.mainCamera = useCamera;
14.         }
15.     }
16. }

 

Also, I had a question in the Work-in-progress thread about how to access Tenkoku time/weather variables from code. I should have an update for the user manual that explains this soon, but in the meantime you can take a look at this post here... http://forum.unity3d.com/threads/tenkoku-dynamic-sky.253589/page-5#post-2076986

 

Hi Justin, having a small issue with clouds not rendering to horizon.

No clouds between the yellow lines.




Adjusting the overcast does not effect the sky colour within the band, so it remains much brighter then sky where clouds are rendering.

 

Hi! Just purchased TENKOKU. So far it's great, but I'm having issues.

Is there any way I can keep the default Unity render fog?
I make heavy use of it in my game, it's absolutely essential.
I'm not going for realism, and I want to maintain the same visual style.
Can I turn the TENKOKU fog off?

Another thing, is there a way to set a 'preset' sky style that you can save, similar to SUMINO? I am using that as well.

I'm also having one of the image effects interfere with the way my own particles look. There is a 'bleed over time' of my particles, which is very disorienting. When I turn off 'fxAuroroa' it stops, but that also breaks TENKOKU.

Thanks!!

 

Hi markefus, thanks so much for your purchase! You can turn off the tenkoku fog by going to Tenkoku DynamicSky-->Sky Sphere-->Fog Sphere and turning off this object's "renderer" component.

However, Tenkoku does take over the scene fog, you're right... let me review this a bit as I think this is a holdover from one of the beta versions. I'll see about turning this off, and send you an update.

Unfortunately, there isn't currently a preset system with Tenkoku. You can setup all the settings as you like before pressing play... or... you can take a look at accessing the individual variables through code, as noted here:
http://forum.unity3d.com/threads/tenkoku-dynamic-sky.253589/page-5#post-2076986

Instead of turning off the fxAurora object, try going to the Tenkoku settings under "celestial settings" and turn off the auroras there? Also, can you send me a screenshot of what this problem looks like on your end, and what image fx you think is causing this?

 

Hey chingwa! Would really like to see a interactive demo of tenkoku. Is there anything available?

I have a few other questions:

- all those cool features of the beta made it to the final release? Those fantastic images on page 1,4 and 5 (http://forum.unity3d.com/threads/tenkoku-dynamic-sky.253589/page-5#post-2076986) could be created with the final release? I heard those nice clouds dropped because performance issues?

- will tenkoku work in editor mode, too (no black out)

- does tenkoku work together with horizon(ON), maybe you or your customers could share some experience?

- do you see any problems with tenkoku fog and advanced foliage shaders 4.0?

Thanks in advance!

 

Here are two images describing the problem.

The first is what the particles are 'supposed' to look like.
The second is the particle bleed effect I mentioned.

Commenting out the LateUpdate code in ParticleAuroraHandler.js actually fixes the problem; so it's somewhere in there. Turning off the aurora in celestial settings does not fix it for me.

And yea, keeping the default Unity fog is essential. I can't use TENKOKU without this feature
Is there any way I can do this manually before waiting for an update?

 

@markefus I just sent you an update via email I'll take a look at the aurora rendering and try and see why they would be interfering with your other scene particles.

 

@MS80 I'm currently working on a demo, It should be ready pretty soon, but I can't say yet exactly when yet.

With the exception of the original clouds shown on pg1-4, I believe all the features I talked about in the original thread have been implemented. The final implemented clouds are as shown in the video.

The lighting does now work in editor mode, though I'm still trying to work out how to actually show the sky in editor mode (not sure if this is possible actually, but still experimenting). I haven't used Horizon(ON) or the AFS myself, so I can't make a definite comment. I did have some feedback during beta about AFS and that they worked better than the normal built-in unity tree shaders... but again this may be anecdotal. If you want to send me some scene elements/shaders I could test them for you before you consider purchasing Tenkoku...

 

Hi,

Any idea if this is compatible with the new "Realistic Water" ... here https://www.assetstore.unity3d.com/en/#!/content/33434

and here : http://forum.unity3d.com/threads/realistic-water.312612/#post-2031038

 

Also, are there any plans to get more volumetric clouds back in? ... like those in the initial posts. I know they were expensive which no-one wants (well - perhaps some do - as long as its a completely separate option), but just wondering if you're thinking of anything to replace them, as the current clouds lack volume.

 

Hi Guys,

Just wanted to show off what i have been doing with this. Had an issue, created a demo project, and Justin got back to me over night with a fix - there are still a few rough edges which i don't expect will take him long to smooth out, but imho this is the best weather and light asset on the asset store. Double thumbs of for responsiveness with a fix as well!

Cheers,
Adam.

 

Chinwa, will the set camera at realtime functionality make it into the next update? I could use this feature.
Also...+1 for C#

 

+1 on c# as well - don't know why anyone would code in javascript when you have the power of c# available

 

@mwituni I don't know how they do their reflections in that water asset, but I assume it would generally be compatible, yes. I'll probably not be going back to the original clouds, however I would like to improve and add to the existing cloud system. It does have a volumetric effect when viewed from below, though certainly not like the original method.

@AdamGoodrich Beautiful scene, thanks for posting!

@jc_lvngstn Yes, it will definitely be working in the next update

Noted!

 

'Cause I was sold a bucket-o- lies by Unity when I first started this whole mess... that the programming language didn't matter, "look you can pick from 3 different languages!"

It's like asking your friend if you need to wear a tie to dinner, and they say "nah wear whatever you want" then you show up to dinner and everyone has ties and look at you like you're a street urchin for not wearing a tie. Then you ask your friends (who are now suddenly all wearing ties) why they didn't tell you to wear a tie and they say "well it should have been obvious that you needed a tie"... (mumble grumble grumb)

Looks like I'll have to buy a tie.
