Title: Reflections direct light + glass problem
Post by: oh.stv on 2015-10-13, 17:39:46
Hi all,

i noticed some strange behaviour of my wood Material.
Its almost as if the reflection Channel turned dark at the Spot where my HDRI Light hits the geomtrie. And that just if i have my glass layer is switched on.
In my Channels the realy dark part is in the Direkt Light Channel though.

The Material is pretty standart, nohting fancy, AND looks good all over the Scene.
There is no problem with my geomtrie, how i said, if u turn off my glass layer everything seems decent.

My setup, is just one HDRI (1739 ) as light source, gamma 0.9, in the Diffuse channel. 
The Glass material is just standart with IOR 1.52 in both reflection and refraction. Just geometry wise its quite heavy with 2 solids both at 0.5 cm thickness and 1cm appart.

Thanks for ur Help!


I use R15 and A3 btw.
