I haven't done much lighting before but I want a dark scene that's in a mine. I have some issues that the lights just cut off and make some weird lines. There is a point light on the torch with the mode set to realtime and the particle system is set up the same way. Can some one help me understand?
You might be exceeding pixel light count limit. Any additional light which exceeds such limit will be reverted to a vertex light. This is an inherent limitation of the forward renderer. You could either try adjusting pixel light count value in the project settings, or switching to a deferred rendering path. Alternatively, bake your lights.
