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"

Do Maya's triangle counts matter, or only the poly counts?

I know this question seems redundant, but I did a bunch of searching and didn't find anything that was quite what I'm looking for, so please bear with me.

In Maya, I have a triangle count and a face/polygon count. I understand that when I export my mesh as a .fbx files, I can either export it as quads or triangles, and if I export it as quads, UE4 will automatically convert the mesh to triangles at import time.

Essentially, my question boils down to this: Will the .fbx file include vertex information which UE4 will use when drawing the triangles, or will it simply include information about the quads that UE4 will use, presumably largely by simply splitting them?

The reason this seems relevant to me is that the mesh in Maya might have extra vertices along a straight line that don't actually change the shape in any way, so I need to know if I should be cleaning those up. Thanks in advance!
