After reviewing the docs again I saw it mention, “Point light shadowing not yet supported”.
So, this subsurface is intended to produce a light scattering effect, with all lights but the one light type that will best describe a wax candles primary function? Providing light from a flame which is best described by a point light?
In this particular scenario would you know an alternative to using a point light to emit light that would replicate the emitting nature of a point light?
