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"

You were really close to what you want. To exclude the undesirred sphere use intersection end depth, you can setup your material like this. Hope this helps someone! alt text

It's possible that one is the start and the other is the end of the trace. I'm not familiar with this technique.

I think so but I wonder why the circle separate. It should be 1 circle. Do I use this node in the wrong way.
