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"

How to create Triangle UV map for Custom Mesh

Using custom mesh, I've created tesselated octahedron and now want to map texture onto triangles(like on screenshot), but info on MakeCanvasUVTri seems to be quite sparse. So, are there any other methods to create UV map for custom mesh or to highlight edges? alt text

usually you would just uv unwrap the mesh in a third party program such as blender or maya. this allows you to place the uv as you choose and in the shape that you like. the picture you posted even looks like its from blender.
