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"

How to Override Tessellation Maximum

My mesh does not seem to tessellate beyond a certain point. I can only further increase the resolution by pre-tessellating the base geometry. After some research, I found out that the tessellation is limited to 8 subdivision levels.

I found this source which allows me to change the maximum tessellation, but it appears to be outdated. The source wants me to modify a usf file where the maximum tessellation variable is stored, but I can only find ush files.

Product Version: UE 4.21

This is still valid and applicable. The file is Flat Tessellation.ush. Lines to change:


CompositeTessellationFactors = clamp( CompositeTessellationFactors, 1, 15 );

Where 15 is should be replaced to your maximum tess value, up to 64
