self._mgr is a shortcut for this

Considering all the access of mods.fogenv, it would be nice to cache that value for the (small) performance benefit and less verbosity.

The preferred method for doing this is to have blender store the attribute name of the constant and use getattr to apply it.

I don't think I can do that in this case because the plasma_fni enum values don't match the names of the constants, but are already in use in existing data :(

Methods should only have one line of whitespace separating them (see PEP8)

Korman prefers to hide unused properties.

Hiding the start field caused some annoying visual jumping of the end/density fields when toggling between fog types. I tried to work around it by adding a blank space if we didn't need the start field, but apparently Blender ignores that :\

This seems like a misnomer when you are referencing a world. It's also confusing when accessing bo.plasma_modifiers.fogenv.fog_env because of the redundant naming and inconsistent spelling.

Updated. Only thing I didn't address was the lookup table for the attribute names, because I think we need to keep consistency with the existing |

I've been sitting on this for awhile because I'm not sure how much I like creating a new ID block in Blender to store fog environments. I'm thinking it might be better to refactor the way fogs are done from the ground up. Namely, instead of having the fog properties stored directly on the world object, we should have a collection of fog properties on the world. I would argue the default fog environment should work like the Default page does, we default to either no fog or D'ni fog but allow the author to override this by creating a nameless or "Default" fog. |
Adds a new Fog Environment modifier to allow per-object fog settings. Multiple objects can reference the same FogEnvironment.
This is implemented by creating a new Blender World for each fog environment and reusing the existing
plasma_fniproperties. This works without changing the default World associated with the Scene, so the global fog settings remain as they were.On the subject of global fog settings, if you try to add the global World as a fog environment to an object, it is silently ignored to avoid polluting the PRP files with unnecessary keys. Hypothetically there's a potential optimization where we could avoid adding the fog environment ref if the material is flagged as NoFog/ReallyNoFog.
Worth mentioning that PRP-based FogEnvironments are static and cannot be animated or modified by Python.
