mental ray walkthrough
show user profile  roccodiablo

I'm going to be rendering a walkthrough using max 2010 & mental ray.

I did a test yesterday by rendering out the final gather map at a quarter of the final resolution. Should this cause any problems? When I rendered a still at full resolution using the saved fg map I thought it was possibly a little blurred but not enough to be a problem. I was just curious to see what would happen as it would save a lot of time.

Anyone ever done that? Or is there a obvious reason why?

I'm prepared to be proved wrong, but i'd render a full size fgm but only render every 3rd or 4th frame. Freeze to that map and then render. That'll save time and the fg should be good for the animation.

yeah that's true enough - the incremental saving of the FG map seems to be done thing for scenes with just the camera moving.

I have to say, in all the stuff I've read about saving a fg map for animation - I've never read anything about rendering the fg map at a low resolution so I guess I should assume it's not worth doing. It didn't seem to affect the still render but maybe it would affect the old flickering problem if I used a smaller fg map.

I was just hoping I'd found a quicker way to save the fg map. I'm running out of time to be doing test renders so thought I'd ask here.

Thanks as always for the reply, westcoast
