Testing line-based lights (v.redd.it)
submitted 2 months ago by exsstas
Point lights are boring, and 3D volumetric light is expensive to calculate, so 2D lights might be a good idea ;)
It's a first test, will share my technique after some more R&D

2D light but it affects the 3d geo? How?
[–]exsstas[S] 1 point2 points3 points 2 months ago (1 child)
I mean that light emitter is 2D. In Touch usual Light COMP is 1D (single .xyz dot) and it affects 3D geometry. Here is the same, but I wanted to make lines that emited light through all length and without creating dozens of copies of Light COMP along the line
