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"

Ugly border around objects in post-process shaders

Hello all, I am currently trying to put together a cel-shader using the usual post process technique. Instead of just picking dark or bright though, I'd like to map different light levels to tints on a texture. I am met with an issue when I get to sampling the texture for the proper tint level. Here is the result of the part of the material that gives me issues. alt text

Notice the white pixels around the edge of the sphere on the lower left, and the gray pixels around the edge of the sphere at the top. Those pixels result is ugly artifacts in the final post process. Here is the node setup to replicate this: alt text

And also, here is the texture I am using as the color ramp.

alt text This seems like a simple thing, but I guess I must be missing something. Any ideas?
