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 can I rotate a cubemap / camera vector ?

Hi, I am using often cubemaps (HDR pictures) in the emissive channel of my glass material to fake reflections. But I am not able to rotate the cubemaps to adjust my reflections. How can I archive this?

I have attached a picture of my material setup.

Best regards, Andreas

Hi Maxwell,

This is the typical setup used to map a cubemap onto a surface and allow for rotation along the Z axis. This is also set up so the cube map will work in a location other than world origin.

Let me know if that helps!
