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"

Weird shadows on my mesh!

Like you see on the image below there are weird shadows on my static mesh. I exported the wall from Blender. I created a Lightmap and a UV Map. If I put the mesh on the ground (Landscape, BSP, Static Mesh) there are these weird shadows... Hope anyone of you can help me!alt text

Maybe its a problem with shadow acne, try to adjust the Shadow Bias value in your lightsource.
