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"

I figured out what was causing the problem, it was to do with passing the heightmap through the custom node. The resulting texture was unable to be used as a height input. It's been a while since I fixed it, but it was to do with a conflict between vertex shaders and pixel shaders I think. I just skipped that node in the material for the hieghtmap as it's purpose was to apply Mip-Mapping correctly on textures contained within an atlas - important for diffuse/normal, but not so important for the the heightmap, which controlled the blending between different material layers.
