A very simple Video tutorial explaining how to setup an HDRI map in to vray.
ok .. u open vray environment then max environment?
then u don’t use max environment
i guess is 1 step in + … there is no need for that … pretty sure that HDRI map will not be use as a visible background
…
or is trick i don’t know 
what you are doing is overiding max’s enviroment and then using the hdri as the skylight and also the reflection which is also overiding max’s.
well..hmm… overriding max BG is ok, but why using the same map for both ..vray and max?
One advantage would be to use a hires JPG for the BG (which is visible in the rendering) and a lowres HDR for lighting.
btw,
have a look at the
SDR-Project Forum, where we offer a (max/lw)script for loading different enviroments with one mouseclick the way i wrote before 
Natty - the link doesn’t work. Could you reinstate it?

Thanks for the tutorial mate. But i have problem, how can i make that hdri map affects in objects and materials i have in scene? I mean i want my objects reflect that hdri.
use a vray material… turn the reflect to grey for example .. then put the hdri in the vray override enviroment reflections ..
Thanks for the clip Natty. Looks like you have a nice libray of HDRI’s. Can you give us some links to any free downloads?
Im trying to make this thing work .. but the file that I download never works.. it always says.. “unable to find a suitable codec (vids:div4) to compress the video stream.. you will not be able to view the movie”
Is there any way of getting around this??
Leo

Hmmmm… Ive tried it on both computers and still am having problems.. I know that it works because I remember downloading it on my friends puter…and it worked there…
hmmmm… :?

Leo: Download this program from download.com and install only the codec. Then play natty’s exe file
Thanks Lupaz… It worked out great .. sorry for the late response…
Take care ..
