[alekpanfilov]

Hey Guys,
need some help with image opacity/transparency in simple shader visible thru VDB Scattered medium .. trees in the fog.

Overal scene view:

checked - it's visible only in Volume channel - took one tree closer:

VDB settings:

Tree shader - straight forward ... they are scattered x25000

Octane settings:

Any ideas?

Any clue would be appriciated.


Thnx,
Alek

Found a tweak and it looks ok!

Changed Volume Step lenght in Scattering Medium in VDB settings to ~1.5 instead of 15000 ;] ..
