vray 1.47...faster...how?

[chow choppe]

Hi everyone,

 

i use Vray 1.47 for my renderings but i find it very slow

my comp Specs are pIII 3.0 ghz with HT

2gb ram

160 gb sata HDD

 

When i used to use vray 1.09 it was quite fast...

but vray 1.47 is real slow

Or maybe i am not using the right optimisation settings

can anyone help me achieve faster renders with vray 1.47

which values do i need to optimise to make it fast.

i would be really happy if u guys can put here a list of optimisation settings

 

Thanks

should i use the default settings for lightcache?

posting your settings may be easier as people will have many different preferences for setting a scene up. if you post the settings your already using we'll be able to see if any too high.

ok will do that ASAP

There are a bunch of different things you can do:

 

Light Cache has samples, passes and sample size settings - any of these can be reduced or increased, compromising between quality and render time. I ususally drop quality to samples under 500 and size over 0.04 until final rendering. Irradiance Map has the presets, you can use low for tests and increase for final, drop HSphere subdivs to 20 for test renders, even go to custom mode to drop the rates (negative numbers are subsampled - using multiple pixels per sample, 0 is 1:1 sampling, positive numbers are supersampled - more than one sample per pixel - and are usually not needed). In some scenes you can sample GI at very low rates, like -5/-3, without losing quality.
