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"

HOW do you use bump map (not normal map) in UE4?

This particular case I have a door with a triangular extension bars. Now I know how to use a normal map but I am wondering if for this case a bump map would allow me to make the extension bars look more 3demimmensional. Ultimately I can just extrude the bard in geometry.

PS; HOW do you use bump map (not normal map) in UE4?

Bump maps are the blue channel in a normal map. I think what you're looking for is parallax occlusion. I don't know how to do this in UE4 but I know some of the materials in the sample content have a lot of depth in them, perhaps they can help you. The materials I'm referring to are the rock / cobbled stone materials.

See BumpOffset node. That is what UE4 uses to get parallax occlusion.

Here is an example from Wiki:

so essentially the normal map of the model is used to apply both normal detail and bump map at the same time correct?

Sorry to necropost, but in case you're still looking for something, I do have a general purpose parallax occlusion mapping solution available! https://forums.unrealengine.com/showthread.php?69920-Displacer-Best-Virtual-Displacement-Mapping-Toolkit
