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"

billboard material compensated for object rotation?

So... I'm trying to make a billboard material for a tree LOD, but I'm having issues where the object's rotation is messing with the billboarding. This is two meshes: alt text this is what my billboarding looks like: alt text this is my material: alt text how can i fix it so that my billboards always face the camera? I can't figure this out. i think i need the objects rotation to plug in there somewhere, but I cant find an object rotation node in the material.... any help?

ok so that might not be the easiest thing to read... the billboarding works, but is always skewed against the mesh's rotation. if the mesh has no rotation, the billboarding is fine. with any rotation, the billboarding is skewed along that rotation. here's some pictures that might make more sense: this is the mesh. notice that the trees have different rotations: alt text

here is the same meshes, but with the billboard material. notice how the billboarding doesnt exactly work...: alt text
