Tips for Efficient Lighting
Lights are expensive in terms of performance, so use them sparingly. A
few tips:
-
In general, two or three lights per button is the limit for acceptable
rendering speed.
-
Make sure the materials in your scene have a reasonable amount of
emissive color so that objects are still visible even if lighting is
low.
-
Button magic has a limit of eight lights per scene. Although more can
be added, only eight can be active at any one time.
