rendering time problem - PLEASE HELP!!

[GoncaloP]

Hi Cocolas,

Your scene have 3 major things that slows down everything

1- Did you ever try to setup a small scene with 20 lights with Vraysoftshadows? It will be ever slow if you use them like this... worth with 8 subdivisions, you can try to use only 3 and reduce the light size but... still slow. better with shadow maps or vray standart shadows

2- Very strong multipliers for the lights without fallof square attenuation...

3- You are forcing to much the object lights with very high multipliers too, and better to use a black diffuse color instead to avoid them to be included in the irradiance map process

Regards,

Gonçalo

thanks much. Goncalo.....most makes sense - however, when you say:

2- Very strong multipliers for the lights without fallof square attenuation...

do you mean the inverse square decay in the lights?? I am using manual attenuation controls to achieve a similar thing but w/ more control.....is that similar to the decay??

this is the modified scene, with correct decay on ligthing (inverse square)
hope this is help you.
I've also replaced the self lighting geometry, there is vray light instead.

thanks much Robing - appreciate your time with this - it will help me learn how to light correctly....

is there any way you could post a max/viz 4 version? reason is I'm at work right now till tonight (my time) and we use viz 4 here - I only have max 5 at home.......

I considered using vraylights instead of object lights in the beginning but it seemed that they took longer then object lights.....I'm courious to see your setup

yes they took longer in a way, but even if u use low setting for GI calculation the shadows will look very beautiful (wouldnt with objlight) . So summa summarium, it might be faster.
