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"

Adding scale to Billboard Material (World Position Offset)


I am working on a billboard material for Landscape Grass meshes. While Foliage lets you assign random scale on meshes, Landscape Grass doesn't -- hence I'm trying to add random scaling inside the vertex shader.

In the attached image, both parts work individually, but I can't figure out how to combine the World Position Offset instructions without distorting the billboard meshes.

Any help would be appreciated!

Many thanks in advance.
