I have more. Remember I said I believe I have not taken everything into account. There is refraction!
How does this affect things? Hmm? Can anyone guess? It has to do with the attenuation calculation, using the 1 / cos(alpha). This is actually not the correct angle, i.e. the angle of incidence is not the angle of transmission, therefore the distance of transmission is different, therefore attenuation is different, therefore opacity is different.
Fascinating stuff this. Both my nylon shader and my glass shader are becoming very much more than any I've posted before.
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)
