Whenever I load a scene where I am doing Immediate Mode Drawing after building to Android, using

using (Draw.Command(cam))

I get the following runtime error (I have Compatibility Mode disabled.):

2024/12/11 21:31:22.985 24901 25004 Error Unity NullReferenceException: Object reference not set to an instance of an object.

If I disable the script that is using immediate mode drawing, the errors disappear.

Reporting a bug? please specify Unity version:

6000.0.30

Reporting a bug? please specify Shapes version:

4.5.0

Reporting a bug? please specify Render Pipeline:

URP

I have the same problem as airoll described above on Quest 3 using Shapes 4.5.1 and Unity 6000.0.46f1. When enabling compatibility mode, it works.

I keep trying to find out what has gone wrong with Shapes as it's necessary for my game. Today I was at least able to get an error from the adb logs on Quest:

AndroidPlayer "Oculus_Quest 3@ADB:2G0YC6LF6000D1:0" A non-multisampled texture being bound to a multisampled sampler. Disabling in order to avoid undefined behavior. Please enable the bindMS flag on the texture. UnityEngine.Rendering.Universal.UniversalRenderPipeline:RenderSingleCamera(ScriptableRenderContext, UniversalCameraData) UnityEngine.Rendering.Universal.UniversalRenderPipeline:RenderCameraStack(ScriptableRenderContext, Camera) UnityEngine.Rendering.Universal.UniversalRenderPipeline:Render(ScriptableRenderContext, List`1) UnityEngine.Rendering.RenderPipelineManager:DoRenderLoop_Internal(RenderPipelineAsset, IntPtr, Object) [./Runtime/Shaders/ShaderImpl/ShaderTextureProperty.cpp line 496775000]

This error repeats itself every frame.

Also wanted to add, I had no problems on Unity 2022 and the previous version of Shapes with Immediate drawing on Quest.

While I am not getting that error, I get this message instead:

Same Unity, Shapes, and URP version as the above. Using Quest 3 and Vulkan.

In my case, adding some Shape game objects to the scene they render just fine. However if I override DrawShapes(Camera cam) for Immediate mode (which I use extensively in my project) nothing gets rendered at all, just a black screen, and the above Vulkan warning being spammed in ADB. Even just doing a simple override like this will cause the black screen and nothing being rendered:

public override void DrawShapes(Camera cam) { using (Draw.Command(cam)) { // Nothing here } }
