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

[raphael-ernaelsten-heaj]

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

…

Will the “problem” be fixed/bypassed? Or will you just note in the
docs that this particular case won’t work?
Quite likely not fixed, or not soon.

On the same matter, will there ever be an easy (and reliable) way to
get the raw bytes for render targets?
I currently have to set my render texture as the active one,
texture2D.ReadPixels(), set the original one back as active, then
GetRawTextureData() on the texture2D. This is heavy and not reliable.
Being able to directly Graphics.CopyTexture() on my render texture
would bypass the “set as active” part. Still not optimum but it would
b something.
But if there is hope to be able to GetRawData() on RenderTexture, I am
a taker
Right, that would be more useful. We haven’t done that yet, but someday hopefully we will. It’s on someone’s TODO list.

PS: I can understand it is late for 5.4.0, but you still have no plan
to implement CubemapArray (TextureCUBEArray) in the future?
In the future, yes. In 5.4, no
