Help with (Rhino) Vray Rendering

[tofanrafati]

Hello Everyone, First post, long time passive learner (aka lurker).

 

I've hit a snag and could use some assistance. I have two specific problems:

 

1) I have this interior scene I've managed to do in the past. Since then, I've learned a couple of tricks, added a few objects, added a better resolution HDRI image, etc. and now the acid-etched window takes forever to render. I understand it's a complex object, but there has to be something to bring the final rendering time down while retaining the quality of the reflections of the glass.

 

My settings are:

 

Adaptive DMC

.Min subdivs - 1

.Max subdivs - 4

Antialiasing filter

.Catmull Rom

..Size - 1.4

DMC Sampler

.Adaptive amount - .85

.Noise threshold - .01

.Min samples - 8

.Global subdivs mult - 1.0

GI - Irradiance Map then Light cache

Irradiance Map

.Min rate - minus 3

.Max rate - 0

.HSph. subdivs - 80

.Interp. samples - 100

.Clr thresh - .3

Light Cache

.Subdivs - 1800

.Sample size - .02

.Scale - World

.Numper of passes - 5

.Depth - 100

Caustics - off

 

 

2) A transverse cross-section and the lighting through the glass is too much (over-exposed?) . Again, I've managed to get it right in the past, but I don't know what setting I changed to make it like this.

 

Any advice?
