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"

Loosing material information when migrating

I downloaded the automotive material pack from Unreal. When I open the original project, everything looks fine, the texture are beautiful. However, as I migrate the folder into one of my project, I loose some information on the material. I get no error message anywhere, would you guys know what is causing this issue?

Before anyone ask, I changed absolutely no setting between the two project. Mats have the exact same value. From what I can tell, it seems linked to the ClearCoatBottomNormal node. When I delete this node in the parent material the good mat look exactly like the bad one. But in the case of the bad one, removing it or re-applying it changes nothing.

I found the solution after a bit of searching. To see the clearCoatBottom you first have to activate it in the project setting under engine/rendering/material

Found the solution in the unreal documentation here : **Using Dual Normals with Clear Coat**
