vray speed up render process

Postby tsomek » Fri Nov 02, 2018 3:21 pm

Hi all,

So, as surely all of you out there, I'd love to accelerate my render process - especially when trialling things out in my model.


Does anyone have any advice on how to speed things up - especially the "processing scene" part?


To give you an idea, it takes about 5:30 minutes for a 600x450 render, most of which (3:20) is consumed in the "Processing scene - components definitions". :roll:

This may not seem like a long time, but it takes it's toll when just trying out different designs, lights etc..

Basing this on my current file with following statistics (including nested components):
163MB skp file
1.5 million edges
840k faces
250 components
2200 component instances
1700 groups
185 materials
"default vray" interior low quality settings
Dynamic Memory limit at 5000

I
- am generally a careful modeller
- try to import reasonably sized components & textures
- use vray proxy when using multiple complex components
- purge components, materials etc frequently
- use test quality settings when trialling
- have tried switching off layers of items not visible in the current scene (and have found this doesn't help)


Many thanks!!

PS, I'm running
sketchUP 2014
vray 1.5
on win7 ultimate 64bit
on
AMD FX-8350
8GB RAM

Goggle Vray speed vs quality
P.S.In 2018, your PC is weak for rendering

Hi rv1974,

Thanks for your reply.

I will google and look further into this, but any overall (simplified) tips from you?

Also, what would you advise to improve my "weak" PC?

Many thanks

Tweak noise threshold (.03-.1 for tests, .005-.01 for finals) and Max subdivs. Switch to v3.6+! Disable 'Retrace' while testing.
Hardware minimum: Latest I7 32gb ram, healthy SSD, gtx1080ti or better.
