i placed one in an instance layer, and its working great-- only it's not covering the entirety of the room. im assuming its got the wrong room size, but i'm not sure where to change it. never worked with shaders before so i'm nervous to poke around under the hood hehe.
that aside-- thank you so much for doing this. this is seriously incredibly modular and fantastic. i was so upset when i learned i wouldnt be able to use the fx feature but this is just game changing.
