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"

Change the light color when the light goes through a crystal

Hello. I want to achieve the next effect alt text

I tried to make a translucent material but the light doesnt changes it color when it pass through it.

Is there any way to achieve that effect? The crystal can be moved it so i cant make an static scene with the ilumination. I reed an article to make it with light functions but only when the light and the crystal are static and in this case, the crystal and the light are movable.

Thanks for your advice

There is no easy way to do that with dynamic mesh/light.

You can use light functions.with dynamic light and mesh, but light function is just a material projected by light actor, so you should setup everything manually.
