Glass transparency alpha. How do this?
Posted: Mon May 28, 2018 2:18 pm
Hello guys!
Final image what i need - PNG with transparency glass (example attached)+reflect+shadow which looks like greate on all backgrounds (black/whiate/colors).
It is necessary to make it for 1 render, not 2 but only 1 if it possible.
I saw as it is done by "photographers" in post-production - https://www.youtube.com/watch? v=TGJTruSAEKM&t=621s. In octane it seems to me it is made easier more accurately, at once receiving necessary "pass". On a white background the glass has to look also as on my example with preservation of all refractions and reflections.
Inclusion in material of the Affect alpha glass, allocation on a mask from channels of refraction and reflection don't solve a problem (((, I receive not those an alpha channels which are necessary. Most likely I do something not correctly in PS, maybe blends modes/inverts/layers position, i don't know.
Ask of community help/hint me.
Thanks
