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"

I am not familiar to Poliigon and it's content. But generally a gloss map is the equivalent of an inverted roughness. So either open up the gloss map in an image software and simply invert it and export as roughness, or invert it in the material (not as clean and generally not preferred) alt text

As for the reflective map, there should be no need for it in a PBR workflow. But it's the equivalent of a specular map: https://docs.unrealengine.com/en-us/Engine/Rendering/Materials/PhysicallyBased

Hope it helps!

Oh btw some of my materials are reflective but at certain angles those reflections disappear.
