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"

Using Emissive lighting on Render Target materials.

Hello. I'm currently making a sort of TV wall. Really big. So I was wondering if it was possible to use the Render Target texture as emissive to illuminate the space (it's an enclose space with no exterior lighting). I can get the emissive to work properly with LPVs (I need it to be dynamic), but I would like the Render Target to determine the brightness of the scene (if the render target captures a dark scene, then the room would get darker). I've tried faking it with light functions, but given the aspect ratio of the wall, the sphere/capsule of point lights and the cone of spot lights don't make the cut.

In short, how can I turn the Render Target texture emissive as well? If not possible, how could I fake the screen effect?

Found the answer on the forums: It's necessary to have a constant Directional Light to feed the LPV. Since I was trying it on total darkness, there was no way I could see it.
