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"

Material Instance ignores Phys Material overide

Hey, has anyone here been successful in setting up Phys Materials on a Material Instance and having that different Phys Material be returned on a Hit Result?

With a normal Material applying a Phys Material seems to return just fine, but Material Instances don't seem to apply the new Phys Material/Surface type. Anyone else run into this problem?

Repro:

  1. Apply Phys Material 1 onto a Material

  2. Create a Material Instance of Material above

  3. Apply a different Phys Material 2 (with a different surface type) onto Material Instance

  4. Apply Material Instance onto a test mesh

  5. Trace Complex against mesh with Material Instance

  6. Observe that return is the Phys Material 1 from the parent material, and not the Material Instance Phys Material override

Hello,

I was not able to reproduce this issue. When following these repro steps I was able to get the mesh with the Material Instance to return Phys Material 2 override during Trace Complex. I have linked my sample project below. Please let me know if you have any additional questions or information.

Thanks,

Lily
