Per-object settings for Lightmass
Editor Properties: (see get_editor_property/set_editor_property)
diffuse_boost(float): [Read-Write] Scales the diffuse contribution of all materials applied to this object.
emissive_boost(float): [Read-Write] Scales the emissive contribution of all materials applied to this object.
fully_occluded_samples_fraction(float): [Read-Write] Fraction of samples taken that must be occluded in order to reach full occlusion.
shadow_indirect_only(bool): [Read-Write] If true, this object will only shadow indirect lighting.
use_emissive_for_static_lighting(bool): [Read-Write] If true, allow using the emissive for static lighting.
use_two_sided_lighting(bool): [Read-Write] If true, this object will be lit as if it receives light from both sides of its polygons.
use_vertex_normal_for_hemisphere_gather(bool): [Read-Write] Typically the triangle normal is used for hemisphere gathering which prevents incorrect self-shadowing from artist-tweaked vertex normals. However in the case of foliage whose vertex normal has been setup to match the underlying terrain, gathering in the direction of the vertex normal is desired.
