Using ReadPixels to capture GL calls

Questions & Answers
1

Hello!,

I am trying to use Texture2D.ReadPixels to capture the screen and put it into a texture. This works well, except that it doesn’t seem to pick up GL calls, as far as I can tell.

Does anyone know a way to use OpenGL to write to a texture in Unity Free?

So I guess ReadPixels does pick up GL calls after all, they just have to be done in the right frame or such. I found that if I make my GL calls RIGHT before I call readpixels, they do get picked up. It just took me many weeks to discover this fact.
Apologies for the impossible question!
