try calculating fg on draft, on a a4 of 72dpi, and then on 300dpi, using a semi complex to complex scene and you'll see why. i do it for render speed, but also so keep the correct size of the fg solution on a larger scale with very little change in quality

I understand that Pieter but maybe this is where it is going wrong for you?

subset of scene shader, i've looked in the render dialog in the lens shader slot, but i can't find it there, also can't find the topic on jeff's blog.

This is the tuorial here http://www.vizdepot.com/forums/showp...90&postcount=8

But first

You also have to unlock the proceural shader (subset of scene) in your ini file it is a hidden shader have a look here. http://www.lysator.liu.se/~zap/pd/unhide-max.html

It is well worth doing this there are lost of hidden shaders but this ones a gem
Enjoy!!

final camera 1

xeunox · February 29th, 2008

here we go again, cam 2.... delete both fg and gi calcs, changed the exposure to compensate for light changes, and recalculated the fg again, and its artifacting like the 1st image again...

i have now switched of both fg and gi and i'm just using the exposure controll to render out the image, its looking ok, but it has to do, cause my time is up... i will post as soon as it finishes

xeunox · February 29th, 2008

ok well this makes no scence, i tried something, i moved the camera i used in scene 1, onto the position of cam 2, recalculated the fg, and its perfect?!?!?!?

Tommy Burns · February 29th, 2008

Well delete camera 2 and animate camera 1 for all your scenes and images

xeunox · February 29th, 2008

giving up on me hey, i don't blame you with all my flaming

You can render two different camera angles to the same FGM, as long as they are in different possisions. The photon map is view independant so you only need to calculate it once for both cameras, so long as the are no changes in the scene.

The grainyness could be down to either low AO samples or low reflection glossie samples.

One a side note check the scale of the people, they are huge.
