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"

Grass Meshes turn into Blank Geomtry

Hello, I downloaded free grass meshes from here. Everytime I use them they look fine, but if I get some distance between it and me, the grass goes blank. This can't be culling, because even if I just drag it out one by one, the same thing still happens.alt text

I think it was the mesh itself regardless of LODs, TextureCoordinate, or the offset, because I download an updated version here and had no problem with it so far. I just need it to cull from a greater distance.alt text

Hello SoraJr,

From your screenshots and your description I believe this could be an LOD issue. I have a few questions to verify.

  1. Do you have any LOD's on this grass? a.) If so do you have a material/texture applied to that Level at the distance you are zoomed to?

  2. If not do you have a TextureCoordinate node feeding into the texture sample you are using for your diffuse/base color?

  3. Do you have a world position offset applied to this material?

Please let me know the answer to these questions and I will continue to investigate this issue if these troubleshoots do not solve it.
