Split screen drawings problem

Hello,

I want to have a splitscreen with a small screen in the top right as a kind of preview or custom screen.
A split into 2 or 4 screens is no problem but to draw one screen in the top right is, because the big screen is also
drawn into that area. My question is, if there is a possibility to draw the little screen in the top right without the drawings of the big screen.
Or how can i clear the background in that area and then draw the little screen on it.

Thanks in advance for any help

Hi,
I see many possible ways depending on your needs.

1- You can use scissor test to draw your full view at the rear excluding top right corner but it can be complicated
2- You can renderer your preview in a texture and draw a textured quad from your full view in the top right corner
3- You could simply draw a background color quad the size of your preview…

Hope it helps.
