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"

FBX import has flipped normals, how can I fix it?

Hi there,

I'm having an issue with an FBX file I'm trying to import into my level. When I import it, the normals are flipped, and I can't seem to find a fix for it. I've tried everything suggested to me, including flipping the normals in 3DS Max before exporting, but that doesn't help me in this situation, since when I try to bake the lighting, the whole object goes black.

Is there any way for me to invert the normals in Unreal? At this rate I feel like I may need to remodel the object since I can't find a solution that works for me.


Product Version: UE 4.20

If your object turns completely black after lightbuild it has problems with its lightmap (usually not existing/wrong uv channel!!) and not normals... usually when you have flipped normals your mesh/faces starts to glow/emit light!! ...anyway you should be able to fix it in your 3d app!!

In Unreal usually what can help is to uncheck use mikktspace in your object's properties...
