Hello, I am facing a bug in my little project. I am creating a Texture2D of format RGBA_ETC2_UNorm with 8 mipmaps at runtime: Code (CSharp): GraphicsFormat format = GraphicsFormat.RGBA_ETC2_UNorm; int mipmapCount = 8; Texture2D copyTex = new Texture2D(width, height, format, mipmapCount, TextureCreationFlags.None); I found these three line of code work perfectly on Android. However, they will cause EXC_BAD_ACCESS on iOS. The XCode shows that EXC_BAD_ACCESS is triggered in function UploadMipPyramid [inlined]. Any ideas?
