How to recreate the portal shader from Portal
Hi, i'm new in Unreal Engine 4, for a little project, I wanted to recreate the portal frame effect from the game Portal by using the same textures taken from the game there is a noise texture, 2 masks, 2 colored circles, and three gradients (Blue, Orange and Red (I think the third is unused but i keep it)) I've already made a shader in Unity but it wasn't perfect.
I know that the open portal is a second plane with the frame shader above the render texture plane
(Sorry if my english is bad it's my first post)
