Just fixed a bug where the portal would have this weird wireframe surrounding it making it very obvious theres a portal here. However, I’ve been trying to fix the issue where for 1 frame something appears on the screen when u enter a portal. My guess on why this is is because since the portal is a very thin cube, the inside of the cube still exists, hence the blue part. This would require modifying my cube engine into a multi-object engine (pretty hard), but I will give it a try.
