Question by revived · Nov 25, 2015 at 03:07 PM · texture texture2d rendertexture copy readpixels

ReadPixels returns RGBA(0,0,0,0)

Long story short:

 Texture2D textureA;
 public Texture2D textureB;
     
 textureA = new Texture2D(textureB.width, textureB.height);
 textureA.ReadPixels(new Rect(0, 0, textureB.width, textureB.height), 0, 0);
 textureA.Apply();

For testing, I visualized the texture via DrawTexture. Works in the editor and when I build the game for Windows 64bit, the texture has the correct dimensions but it is blank. I read about a bug that I shouldn't use Anti-Aliasing but that doesn't help me.

Thanks for help, folks!

I don't know but perhaps your render texture format differ between standalone and editor?

This function works on ARGB32 and RGB24 texture formats, when render target is of a similar format too (e.g. usual 32 or 16 bit render texture). Reading from a HDR render target (ARGBFloat or ARGBHalf render texture formats) into HDR texture formats (RGBAFloat or RGBAHalf) is supported too.

Perhaps you could try a different texture format?
