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"

Static meshes appear black even though multiple uv channels

So in my level I have a castle scene and the wall are made of a mossy stone brick sort of material, and I made these wall in blender and exported them as a static mesh into ue4, and when I built the lighting, they either appear completely black or mostly black. I am almost completely sure that it is because of the sculpting method that I used in blender, since I have exported other models without using the sculpting method before and it worked fine. I have already tried adding another uv channel and I have looked at several different supposed fixes and none have worked. All help is appreciated greatly thanks!

I know you have tried "supposed fixes" but let me ask something, did you unwrapped that wall ? try using the smart uv project on the second uv channel if this doesnt work try adding a lightmass importance volume into the scene that covers your wall

I had already tried using the smart uv project and unwrapped it, both the diffuse material and the lightmap, and I just tried using the lightmass importance volume, and it did not work. Thanks for the fast response though. Heres a screenshot:
