different resolution,different irradiance map,different time

[Sheridan Pang]

Hi guys!

I'm new to Vray,it's really great!

Here I have a question(maybe stupid):

when I set different resolution for the same scene,
the irra-map's size is different: almost doubled when resolution doubled,
and the rendering time different a lot:almost 4 times when resolution doubled!!!
hi-res takes a lot more time to calculate the irra-map.

I've heard that we can calculate the map in a low-res
and reuse it in hi-res.

But what'bout the hi-res one? Does it make the image more better?
or, there is no different between those irra-maps?

Thanx!

check this one out - he explains when and what the imap res should be based on image res...
