Yes it was Brazil renderer. I remember when this totorial came out it was a must to learn :D

Hi TAO, i think to have spotted few bugs, but i need to know if they are meant first.

sure a bug: when rendering perspective view - no camera, what is shown in render doesn't match the rendered view in max.

I tried clear volume and homogeneous volume.
I added clear volume as fog, playng with the setting delivers always same density.
I added the homogeneous volume to a mesh, followed the blender tutorial from dravia, i didn't notice any change in my renders.
may you share a showcase scene.

Light material, playing with the gain and efficency won't affect lighting in the render.

btw, i can't really test maxtolux since instances aren't supported, i have large scenes with lots of instances, if i hit render now MaxtoLux abort render before running out of ram.

Thank you

I do not think the instance should be a big issue for you at the moment, because i test it with more than 500000 objects (of course low poly objects), and with OpenCl it took less than 6 GB of memory unless you have high poly instanced objects.
Othe part i need to check first.

A very vague rule of thumb is: 10,000,000 of triangles for 1 GB of GPU ram.

Thank you for the heads up. is that the same for system Memory too?

So base on Dade point just hit the 7 number on the keyboard and simply check how many triangles your scene has.
Of course, I'll try to implement instance objects very soon but till then you need to be a little bit patient.

Yes, more or less, keep in mind image maps usually take the majority of RAM in most scenes.

They are all high poly instanced objects, and it goes up to 12Gb ram being still in the middle of the process... before maxtolux abort the process itself.

I'll try to implement a quick solution very soon.

I've cheked the scene by hitting 7
polys 34.771.035
verts 17.742.370
