[RELEASED] OmniShade - Mobile-Optimized Shader

OmniShade on the Unity Asset Store

Website | YouTube | WebGL Demo | Discord Support | Email

OmniShade is a highly performant shader designed for mobile devices. It is packed with a multitude of graphics techiques allowing it to achieve almost any look from realistic to toon to anime, yet also blazingly fast due to a progressive system of calculating only what it needs to for any setting.

It was designed to bridge the gap between Unity's Standard Shader and mobile shaders, but can often look even better than desktop-class shaders due to its high level of stylization, combination, and customization.

All of the sample images above were rendered using only OmniShade. It can achieve almost any look, can be used for games with complex or simple lighting -- regardless, the performance is always optimal. It is quite possibly the only shader you will need for your entire game.

Feature summary
All of the below can be used in any combination with optimal performance!

• MatCap
  
• Realtime shadows
• Vertex colors for vertex painting
• Detail map
• Diffuse lighting + flat shading
  
• Specular lighting + hair highlights
  
• Emissive lighting
• Lightmaps (both internal and external baked lightmaps)
• Normal map
• Rim light
• Reflection
• 3 masked layers
• Transparency mask
• Height-based coloring
• Worldspace shadow overlay
• Vertex-sway for vegetation
• Triplanar projection texture mapping
• Outline
  
• Anime-styling
• Fade with camera distance
  
• Fog
• Environmental ambient & light probes
• Full access to culling and blend settings
• Highly tunable controls for all features

On top of this, you also get:

• Built-In and URP pipeline support
• Progressively adaptive performance
• Set of demo scenes
• Full source code, easily extendable

It's true, the Standard Shader is still too slow for mobile devices. And let's face it, giving an artist Shader Graph is like giving a baby a gun. But it doesn't mean you have to settle for Diffuse shader.

Great set of shaders. Bought it on sight.

What does Progressively adaptive performance mean?

 

Thank you!

It means the shader will compile into different variants depending on what features you enable.
So, if you only use Diffuse and Rim Lighting, a minimal shader will be generated just for that to run on the GPU. If you were to add Normal Map, a little more code will be generated and another shader will be made for that variation. It detects what you use, and always creates the minimal GPU code necessary for optimal performance.

 

This Shader makes even the editor faster! I'm loving it but developing for the Quest 2 and having issues when I run it. Seems like it's only running in one eye and having clipping issues, did I mess something up? I am STOKED to use this Shader almost exclusively if I can figure out what my silly issue is lol thanks in advance!

 

Unfortunately I've never tested this shader on a VR device, although I've heard of one other person use it successfully in VR..

There are some depth and culling settings at the bottom of the shader which control the visibility.
I would start with those, like try set Culling to Off, Z Write to Off, Z Test to Always, and see if it makes a difference.

Thanks for sharing that Ken.

Shader doesn't support Single-Pass stereo rendering,
so if you have problems in VR, one thing to try is keep it on Multi Pass.

 

That's a pretty big ask.

My current project is on multi pass at the moment because I use mirror shader that requires it. It's not ideal and I have plans to change that.

Multipass is going to be a deal breaker for a lot of VR devs.

 

Yes, I just released a patch to support Single Pass Stereo Rendering. Thanks for the suggestion!

 

WOW! Awesome thank you so much! going to test it now! SUPER STOKED!!!!


.. Works perfect THANK YOU AGAIN!

 

Hi, could we have an option on the triplanar shader to use UV0 on the main texture? ( so make moss/snow/etc.... with triplanar top ?)

 

After updating to lastest version I got this error :
Shader error in 'OmniShade/Triplanar URP': invalid subscript 'viewReflectDir' at Assets/Shaders/OmniShade/Shaders/OmniShadeCore.cginc(911) (on d3d11)

 

That's a great suggestion, I'll add support for using UV0 on the main tex in triplanar.
Also, thanks for the error report, will be fixed in the next patch, out later this week.

 

Hi, just updated and I now got 2 error on Standard URP :

Shader error in 'OmniShade/Standard URP': 'reflect': no matching 2 parameter intrinsic function; Possible intrinsic functions are: reflect(floatM|halfM|min10floatM|min16floatM, floatM|halfM|min10floatM|min16floatM) at Assets/Shaders/OmniShade/Shaders/OmniShadeCore.cginc(810) (on d3d11)

Shader error in 'OmniShade/Standard URP': undeclared identifier 'adjNor_world' at Assets/Shaders/OmniShade/Shaders/OmniShadeCore.cginc(810) (on d3d11)


Unity 2020.3.29 - URP 10.8.1

 

Thanks for the bug report, indeed you are correct!
I will have it fixed early next week.

In the meantime, you can workaround this by simply enabling the Diffuse, Rim Light, MatCap, or Specular feature, or remove the normal map and that should make the error go away.

 

Great thanks!

 

Really cool assets!
Hope you are bringing more of the "mobile features" like triplanar mapping and vertex swaying for vegetation, to the PBR version too

Another cool feature would be tessellation.. but I should stop dreaming now, haha.

I have updated my project from 2020.3 (which works fine) but when building the project I get the following error message. I have reimported the asset but still get the same message.

mthawley, thanks for the report. I think I found the problem and am submitting a patch for it.

If you rather not wati for the patch, you can fix it by simply deleting line 348 in OmniShade URP.shader

Code (CSharp):

1.             #pragma shader_feature BASE_SATURATION

 

Excellent thanks!

 

I have a MASSIVE scene I'm working with for a Windows/MacOS release and have done everything I can to optimize; texture atlasing, different types of batching, etc. all using the Standard Shader. I was going to move over and give the Standard Unlit or Mobile shaders a try but I was just wondering if OmniShade might give better results on a Desktop platform.

 

jnbbender, yes absolutely OmniShade is much faster than Standard shader on PC, and has a lot more features than the Mobile shaders. It would definitely be worth a try if you need the performance. The main thing it lacks compared to Standard shader is PBR (physically based rendering), so your results would not look as realistic since you’d need to tune the diffuse/specular/reflection amounts manually. But if performance is prioritized over photorealism, then OmniShade would definitely offer more.

 

Hey, small question again - does Omnishade support instanced indirect crossfade?
It needs the LODDitheringTransition method to work with things like GPUInstancer, so I'm wondering before I bite the bullet and grab the shader.

 

bwacky, I took a look into the GPUInstancer package, and it seems to require some modifications for custom shaders to work:
https://wiki.gurbu.com/index.php?title=GPU_Instancer:FAQ#Vertex.2Ffragment_Shaders

So, to answer your question, no it is not supported out of the box, although if you follow the above directions, it would not seem too difficult to setup (although I can only guess without having tried it myself).

 

Hey there, is there any chance to get spotlights working with these shaders? Do you plan to add support for it any time soon? Besides that the shaders look very nice!

 

Hi look001,

Unfortunately OmniShade does not support spot lights due to performance reasons.

As an alternative, I would recommend using OmniShade PBR on those materials that need spotlight support.
If all you need is a very simple spotlight and you are on Built-In pipeline, you may also try Unity Projectors.

 

Hi. Is there a way to activate/de-activate Enable Outline via script?

 

Does it support Deferred rendering?

 

sichimi1021, no the shader does not support Deferred Rendering.

If you need deferred rendering with OmniShade's features, I recommend you consider OmniShade PBR:
https://assetstore.unity.com/packages/vfx/shaders/omnishade-pbr-physically-based-uber-shader-216249

 

Thanks.
I will consider PBR.
.

 

Is this a character shader? I can't get the same result after unity bake GI.

 

• • I have a problem, the material ball encountered the following error
    

 

• I have a problem the material ball encountered the following error

 

Thanks for the tip, will have those warnings fixed. They are harmless to the actual operation of the shader.

 

Hello,

To change the layer texture via script, you can call

Material.SetTexture("_Layer1Tex", newTexure)

Also, as the shader variant for Layers are detected at build time, you'll also want to ensure there is a texture slotted in there (even if just a white dummy texture) if you are setting the texture at runtime to ensure the proper variant is built.

Thank you!

 

Hello,
I'm making a mobile game that uses assets from the Asset Store, so I'm using URP, and SimpleLit Shaders that I'd like to tune/optimize.
1. I would like to know if OmniShade allows this?
2. Or does OmniShade just create Shaders?
if so then will they be compatible with my assets? optimally, i.e. possibly maximum fps
e which use

 

Hi, OmniShade is a shader (compatible with Built-In and URP), and so is used by replacing your current shader.
It has every feature that Simple Lit shader has, and a lot more. Performance should be on par or faster than SimpleLit, as OmniShade is maximally stripped at build time depending on the features you actually use.

The main advantage in your use-case would likely be possibly improved FPS, and a lot more graphical features which you can enable as you see fit.
