Transparency_Falloff (if non zero) says that the transparency is a blend between the two transparency values that preceed it.
The blending is based on Edge_Blend, and the falloff is actually the same as Edge_Blend Attenuation.
In non-math terms, it means shift the in-between values more or less towards the edge.
In math terms, the blending coefficient is:
cos(angle_of_incidence) ** Transparency_Falloff
Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
