show user profile  chiki_chiki_BANGBANG
hello, im kinda a beginner at using 3dsmax, for my classes at school i need to make a little house using mental ray rendering, i always had problems with the rendering time, i make a movie from some explosion 210 frames, low quality and it took me 72houres to render it !


so now im wanne render a interior scene but its taking ages just for test renderings.. do anyone has any idea what the problem could be? thankyou..

Processor : intel (R) Core(TM) i7-2720QM CPU @ 2.2GHz 2.19GHz
Ram : 12,0 GB

Faster rendering "in general" usually just boils down to lowering settings, thus lowering quality. If you want the best advice you should probably post screen-shots of your render settings, give an example of what you're aiming for... and talk a bit about the scene you're doing. Lights/time of day/materials etc etc.

"I want to render things quicker" is a bit of a broad question. The more you give, the more you get.

Hah, no you'll have to get the images hosted somewhere. Like Photobucket.com, then just post the direct link to the image here. (if possible though, please don't post huuuuge pictures)

>>do anyone has any idea what the problem could be?

you're using a laptop, a desktop of equivalent cost could do it around 3 times faster. other then that there are a lot of performance optimizations you can do to cut down render times without significant impact on quality but as said with no pics we have no clue whats going on.

you have GI enabled yes? each sky portal you are using there is multiplying the GI photon count and you got a lot of sky portals. There could also be some material inefficiency going on here, either way there is no way that scene should be eating 20 mins per render.

Also note that your high/mid/shadow curve is a bit too linear, human eye doesn't see colors linear like that and will find much more colors around lower 2/3's of the curve which presence you have diminished. The images will appear quite contrasted in their lightness/darkness and kind of blurry at the same time in color contrast.

i adjusted some settings, GI is enabled yesh, and dthe curve is diffrent, i saw there are some materials added to object (they have been imported as the .rvt file from revit architecture)

like you see, it took me 35min + to render the scene

can you show the glass materials? i think most of the render time is spent around the low gloss refractions of the window but cant really tell from just the render

i dont really use the premade materials so i dont know how efficient it is but looks high gloss. It is probably your gi settings but speculation only goes so far, you're going to have to remove elements yourself to see whats taking up most of the time
