[Regression] TemporaryRT does not work with EnableRandomWrite

Graphics - General



Priority: 2Necessary for shipping a final release


Severity: 3Secondary functionality broken

1. Open project "" attached in comment
2. There are 3 scenes and the only difference between them are the creation of RenderTexture:

UAV_RenderTexture scene -- created using new RenderTexture()
UAV_TempRenderTexture scene -- created using RenderTexture.GetTemporary()
UAV_CmdTempRenderTexture scene -- created using CommandBuffer.GetTemporaryRT()

3. Hit play on each scene

Expected : You should see animating color on GameView after hitting play
Actual : Black

Regression info:

Version 2017.4.2f2:
- UAV_RenderTexture correct
- UAV_TempRenderTexture correct
- UAV_CmdTempRenderTexture black

Version 2018.1.0f1 / 2018.2.0b3 / 2018.3.0a1 (trunk e5784397efb2)
- UAV_RenderTexture correct
- UAV_TempRenderTexture black
- UAV_CmdTempRenderTexture black

Note: I'm not sure if UAV_CmdTempRenderTexture is supposed to work or not
