Graphics [Bug 800262] Texture2D.GetRawTextureData() returns incorrect bytes after Graphics.CopyTexture

raphael-ernaelsten-heaj · May 25, 2016

Texture2D.GetRawTextureData() returns bytes of value 205 if executed after the texture was copied from a RenderTexture with Graphics.CopyTexture().

The texture is however ok since I can use it in a shader.

FYI
Unfortunately not going to be fixed soon
No solution for getting pixels out of RenderTextures either

Quite likely not fixed, or not soon.

Right, that would be more useful. We haven't done that yet, but someday hopefully we will. It's on someone's TODO list.

In the future, yes. In 5.4, no
