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"

Limiting tessellation to 1 axis?

Hey People,

Was wondering if anyone could help me with this problem im facing, I'm trying to limit tessellation to one axis for a snow shader im making but my current setup is giving me 1 minor issue. It's working, but at a wonky angle, and I don't know why, any help to where I might be going wrong would be awesome.

Cheers :)

if you multiply the vertex normal by 0,0, some value; it will constrain the result to the z axis. alt text
