Decals are lightweight primitives for bullet / blood marks.
|
|
Decals with common materials will be merged together, but additional
|
|
decals will be allocated as needed. The material should not be
|
|
one that receives lighting, because no interactions are generated
|
|
for these lightweight surfaces.
|
|
|
|
FIXME: Decals on models in portalled off areas do not get freed
|
|
until the area becomes visible again.
