If I am rendering to a texture bound to a FBO and will then use that texture as input to render to another texture (and so on), how should I set up the FBOs etc. Should I have one FBO for each texture? Or should I have one FBO and bind the texture I am rendering to each time?
Also, if I do
- Render from Tex1 to Tex2
- Render from Tex2 to Tex3
will it likely stall because the first render hasn’t finished? i.e. should I try and pass time doing other things before step 2?
