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 Stop Mesh from Tessellating Upwards?

Hi Everyone

I'm a relatively new UE4 user and have been experimenting with tessellation, after modelling a structure in Maya 2018 and importing it into UE4 I found that the tessellation in general looks great, however I would like to know if anyone has a solution to prevent the texture from tessellating upwards, I’m using a heightmap for the tessellation and I’m using PN Triangles. (Sorry for nooby question, go easy it's my first post).

Thanks for any help.
