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"

Scale individual point for spline mesh?

I'm using the Procedural Nature Pack system from the marketplace, but I'm sure this is for all spline meshes, but is there any way to implement a way to scale a point of a spline to scale the radius of the mesh at that point?

hmm i suppose i could make a material that adds world position offset to the mesh based on vertex painting, but i cant figure out how the world position offset works. is it just a heightmap, or a normal map? it looks like it takes a normal map, but there's nothing i can find about what texture channel affects which direction. any help?
