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"

Lightmap look ok on hard edge, not on soft edge with normalmap


I have a problem with my meshes; They have soft edge with a normal map and the shadow appears strange on the bottom of the mesh, and the shadows behind the mesh are not great.

I noticed that when the mesh has hard edges, there is no problem with it, and all become ok. I specify than the mesh with hard edge has 64 resolution of lightmap, the one with soft edge has 512. They have the same uv lightmap.

I already tried increasing resolution of my mesh, snapped on grid (3dsmax), increase the bound, played with lightmass settings, and nothing work ..

Someone have an idea?

Thanks. alt text

Hey, did you find a solution for this? Only problem I can see, is that the padding between the UV-Shells is too short. I think this is causing shadow-bleeding...
