Hi there. So I’m mostly a noob with materials in ue4 and I have a post process that creates an outline around all objects on the scene. I don’t know what magic makes it work but it does. That’s great. However, I’ve also placed an exponential height fog which looks amazing except it does not obscure the outline. Betrayal… Presumably, this is because the post process is evaluated afterwards (hence post, I’m guessing). So I’m looking for a way to have the fog affect the outlines. I was thinking that if the fog was also a post process material I can evaluate it at the end, thus solving my problem. Yay! So I’ve been looking around for tutorials or free assets to accomplish this. So far, I’ve found a post process material that seems to create fog. Except it’s not working and my material kung fu is not strong enough to know what it’s doing or why it doesn’t seem to be working for me. I would love to ask people here for any help creating this post process fog, and if anyone knows of a good in depth resource for a terrible beginner on learning and becoming advanced on ue4 materials, that would be killer. But any help is welcome.
For what it’s worth, I have a background in 3D animation software (Maya and C4dD). Here’s a picture of the post process fog material I found.
Thanks!
