Shader errors when building to Android

[camslalom]

Howdy!

I'm working on a project using Unity MARS and any time I try to build to Android, I get the following error involving shaders.

The build will complete, but when tested on an Android device, the pink shader error will appear wherever a Nova UIBlock is placed and the game will absolutely CHUG for about 30 seconds and the frame rate will drop to less than a frame per second before eventually catching up.

When my coworker built to iOS from his Mac it built and the UIBlocks appeared just fine, but building to Android from both his Mac and my Windows machine resulted in the same shader errors.

Are there any specific Android build settings or rendering settings that are recommended that might fix these errors?

Also, does NovaUI support OpenGLES?

We had an inkling that the issue may be related to using OpenGLES over Vulkan, but since we're using Unity MARS, we can't use Vulkan.

I really appreciate any help that y'all might be able to provide. We've been troubleshooting this for a few days now and have not had any luck.

Thanks!

Sorry you're hitting this issue! This does seem to be graphics API related. Which version of OpenGLES are you using? Nova requires OpenGLES 3.1+, if you are able to switch to that it should resolve the issue.

Hi there! Thanks for the response! I tried again and made sure to enable "Require ES3.1" in the Player Settings, but got the same result.

Upon looking at the additional logs from enabling the "Autoconnect Profiler" setting in the Build Settings, I saw an additional message that I didn't see earlier in regard to compiled shaders: "Creation of internal variant of shader 'xxx' failed."

I've tried to fiddle with a few of the shader variant settings, but nothing seemed to remove the error either.

In case the info helps, I'm currently testing it on a new Pixel 7, but I don't know off-hand what device my coworker was building to. I can ask them tomorrow.

Thanks again for your help!

Hello, I am also having the same issue. I've tried it on 3 different android phones. Since a lot of Nova is obfuscated it's hard for me to patch this without completely rewriting each shader.

Would love to see a solution for this before our team is going to have to switch back to a Canvas based UI

After further research, this issue appears to affect more devices than we expected (all phones using Mali GPUs, which includes the last few Pixel generations). Getting this working is definitely a top priority for us and we've begun looking into the best way to make this change, but we can't quite give a timeline at this point.

Aw dang. Alright, thanks for the update. I'll look into other options for the time-being, but I'll keep an eye out for an update for Mali devices.

The fix for this has just been published in v1.3.0!
