Black rendertextures - Android/4.5.2

Unity Engine
,
1

I have Unity/Android Pro (4.5.2) and I draw to a rendertexture and then readPixels to a Texture2D - this texture is always black on the android tablet I’m testing with - in the editor it works fine. No obvious errors in adb log

Edit: the rendertexture works but using texture2D.readPixels no longer works to copy to a texture
e.g.

  • RenderTexture.active = myRenderTexture;
  • myTexture2D.ReadPixels(newRect(0,0, myRenderTexture.width, myRenderTexture.height),0,0);
  • myTexture2D.Apply();

any ideas?

This is an urgent bug for us still present in 4.5.3 (reported Case 626849)

I am trying to test on older versions of Unity to see where it broke (I think it’s a regression) but they require specific old android sdks - keeps throwing errors building the apk

works for me locally
did you try 4.5.3 patch1?

it is not mentioned here but i needed to redo how we do out-of-render-loop rendering to support some stuff here, so your case should be actually fixed (if not, sure poke - i’ll recheck)

Have tried patch, still not working. Did you try the demo in the bug report on an android device? (It is the texture2d.readpixels that is actually not working as before - just on android)
