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 color beam emitter with gradient

hello ppl,

I would like to color my whole scene with gradient, but except one object - the background. I use post process material with image to get gradient and i put it on my plane which is connected to camera and i get gradient only on my physical object. Here is an example (without the background) alt text Gradient looks fine on these dots, but beams are simply white. Why? Plus, I would like to have 100% white material on my background. Is there any way to achieve this?

cheers!
