Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Outline effect in 4.18

I have been following Tom Looman's outline effect tutorial to try to achieve an outline around an object and cannot get it to work. I have followed it on previous releases and it worked fine. Did something change in 4.18 that I need to adjust? I know the Post Process Materials in the PostProcessVolume moved around, so I think I am still placing my material in the right location.

ive never tried this with post processing effects, but you can achieve the same thing by using the fresnel effect in the emissive color of the material https://docs.unrealengine.com/latest/INT/Engine/Rendering/Materials/HowTo/Fresnel/index.html

I believe that only gives an outline inside the mesh, and does not work with rough edges.

I've just tested it and it does work on even latest build (master 4.21). So no changes need to be made.

You have to make sure your meshes have Render Custom Depth enabled. And in case of using instance material, make sure master is properly referenced inside it.
