Get RenderTexture

Hello,

I need to obtain the resultant texture from a RenderTexture each frame in order to use it in this function: material.SetTexture("tex_scene", renderTexture);

I’ve read about the function: Texture2D.ReadPixels but it read the pixels from screen where i have made some geometry corrections. So i just need the real renderTexture.

Thanks in advance

If you have UnityPro: render to RenderTexture, blit to Texture2D, then read pixels from that Texture2D.
