So recently I decided that I want to use the light path node… And I did, but I have a problem.
I wanted to make a kind of realistic “portal” that light can go through it (not to be confused with “light portal”, that is NOT the same thing). This is what I did at first:
So this works fine - the circle, that has a transparent material, Is kind of like a “portal” to a world where the red cube doesn’t exist. But I want the opposite - I want the circle to be a portal to a world where the cube DOES exist. So I should do that just by swapping the diffuse material and the transparent material… right? Well, I did, but I didn’t get what I want:
As you can see, I wanted the outside of the cube to be transparent, but it’s black for some reason - like there’s no material In there. Is there any way to fix this? Please Reply if you can help!
