So, I'm having some issues with lighting in my Unity game. I had implemented torches, which seem to be working fine, but I have a creature (gelatinous cube) that I've put spot lights facing to give it a "glow". The reflected and refracted light ends up having two issues:
- the light abruptly ends at the edge of floor tiles, and
- depending on the position, the light sometimes goes from it's blue color to a reddish color.
I have a short (11 second) video here: http://www.labyrintheer.com/wp-content/uploads/2016/11/Nov-17-2016-21-07-57.mp4 so that you can see what I'm talking about. I've tried changing global lighting settings and playing with the settings on the spot lights, but nothing seems to resolve the issue.
Still images for anyone hesitant to click the video link:
Using a single point light inside the cube, instead: You can see it on the wall in the upper right and the floor at the top a bit. The upload seems to have lowered the quality a bit, but you can still see it. The single light makes it a little bit better, but there's still complete falloff.
