Light groups as a Plasma modifier

[dpogue]

Right now light groups are handled using the Blender's existing (per-material) system, but there are times it is better to assign light groups on a per-object basis rather than per-material.

Additionally, the material light group option only allows setting a single group (which admittedly is not much of a problem since lamps can belong to multiple groups).

I'm imagining a Plasma Modifier to set groups on a per-object basis. My current thinking is that the modifier would always take precedence over the material light group:

if bobj.plasma_modifiers.light_groups:
  # Use the light groups from the modifier
elif bobj.material.light_group:
  # Use the material light group
else:
  # Default

Any reason why the modifier shouldn't combine the material listing with the object listing?

It could do that. My thinking was that you might have a bunch of objects with the same material that you want affected by the same light group, but have one object using that material that you don't want affected by that group, and could add a modifier with no groups to achieve that.
