So I was wondering if it was possible in ue4 to do procedural lighting colour. I am thinking of making a church, but I was wondering like when someone shines their flash-light through the window, the colour would change depending on the colour of the window. I wanted to know if this is possible to do before actually designing the church. Thanks!
If it can i think it will be in light functions, there should be demo of light functions in content examples
Hey AemonBarz -
There is currently no way to achieve the exact effect you are looking for without some planning. Just shining a spotlight through a translucent object will not generate colored light. Our lighting functions are currently restricted to being just black and white cut outs as well. However, there is an excellent forum post on a workaround to use lighting functions to generate light through a stained glass window, here:
