I’m currently working on a portal door system where I got some SceneCapture2Ds moving and rotating around portal doors while facing them and some material alignment tricks to get the perspective right.
The effect is looking really good, but I got some serious performance issues, because rendering space around the portal doors is wasted, especially when the camera is a few meters away from the door.
So I thought about setting up stencils on the portal door planes and only render the scene inside the stenciled areas.
I already inspected the SceneCaptureRendering.cpp, but I don’t know how and where to setup the stencil for drawing properly?
Could someone please help me?
ps. My portal doors are shaped like real doors (rectangles e.g. 1.0m by 2.2m)
