SystemInfo said the device supports render texture formats but logs say it's not.

SystemInfo.SupportsRenderTextureFormat returns true for R8 and R16 but in logs still appear messages like this.

12-16 12:28:06.907: E/Unity(12610): RenderTexture.Create failed: format unsupported for random writes - R16 SFloat (45).
12-16 12:28:06.914: E/Unity(12610): RenderTexture.Create failed: format unsupported for random writes - RG8 UNorm (6).

Does R8 checks RG8? R16 and R16 SFloat are the same?

GPU: Adreno 430

 

Those are different:
R8 Single channel (R) texture format, 8 bit integer.
R16 Single channel (R) texture format, 16 bit integer.

Floats are floats. RG has two channels (red and green), R has only one channel

 

Thanks. This means I understand it right. So, is there any way to check the support of RG8 UNorm and R16 SFloat?

 

@florianpenzkofer thanks a lot. That is exactly what I need.
