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"

Hi Ave Sinistra,

The transmission of light for something like this is possible, the only caveat is that it only works with STATIC lighting. This means no Stationary or Movable lighting will do this.

If you want to do something like this it's good to use a static point light outside the window to create the stained glass effect to transmit light.

You read this How-To here that walks through the limitations and the setup for this: https://docs.unrealengine.com/latest/INT/Engine/Rendering/Materials/HowTo/ColoredTransluscentShadows/index.html

On my forum post here you can download this project and see the results.

If you have any questions feel free to let me know. :)

UE4 does not support something like that as i know, closest thing to that is light function

https://docs.unrealengine.com/latest/INT/Engine/Rendering/LightingAndShadows/LightFunctions/index.html

But problem is it does support color changing, only light brightness, but you might use some trickery by combining lights. Other thing you could use such trickery is decals but it would be... trickier ;]
