the project I've tested it works in Editor or Mobile Devices when the ComputeShader doesn't in AssetBundle. Attach a script using this ComputeShader in a scene or loading by Resources.Load is perfectly worked. but when I build AssetBundle. it doesn't work anymore. I've tested in these situations in unity 2019.4.16f1 and unity 2020.3.11f1 Situation 1: Assetbundle file with a scene and this ComputeShader. Situation 2: Assetbundle file with a scene and another assetbundle file with this ComputeShader. both situation doesn't work correctly. when I call ComputeShader.FindKernel, it always throws ArgumentException: Kernel 'CSMain' not found. code below: Code (CSharp): string csf = Path.Combine(Application.streamingAssetsPath, "computeshader.ab"); AssetBundle ab = AssetBundle.LoadFromFile(csf); ComputeShader _ComputeShader = ab.LoadAsset<ComputeShader>("computeshader.compute"); ComputeShader _Instance_ComputeShader = Instantiate(_ComputeShader); int Kernel = _Instance_ComputeShader.FindKernel("CSMain"); //throws the exception in this line.
