I was rendering a scene and it took me about 10-15 minutes (too much).So i was wondering if there is something i can do to reduce time of the rendering process.Ok i know that if the scene is complicated i can t avoid it however just because you never know there may be some things to do.I ll be waiting for your answers.

You think 10-15 minutes is too long!!!...

Err, friend that is no time at all, most of mine take 2 hours or so, sometimes longer, there are others here that go into tens of hours..

Remove anything that reflects or refracts light in your scene.  Also remove anything that uses fractal materials.  Then start removing anything that has sharp edges on it to avoid AA calculations.  Finally remove all light sources but one from a scene.

You forgot one Shawd, finally remove Vue from your computer..

Ten hours.  I remember when I used to measure render times in days.  Thankfully computers are now faster.  That all said if you're rendering an animation I could understand 10 to 15 minutes per frame being too long.

There may be things you can do to speed up your rendering but we'll need to know more about the scene to really make specific suggestions.  What render setting are you using?  How large is your render?  What kind of atmosphere? Does it include reflections, transparency, hypermaterials, EcoSystems, Infinite Terrains, Poser figures etc?

What a joke! LOL! 15 minutes!

My tutorial on render tips ;)

note though it's for Vue 7 or was it 8?, Vue9 did change things a bit so may need to do some of your own experiments :)

and my renders, yeah, take at least 2 hours. Well worth it in the end, as if you're making a still image you want glorious quality

Please compare these two images

"Final" render settings, default preset, 4 minute render time

58 minute render, custom settings

HUGE difference in quality. And note, I used a scene which was very slow to render due to being encased in a volumetric material object (a cloud ot give a nebula effect), as longer render times due to this means that testign comparisons are easier to show as all renders are much slower, meaing it's easier to show the difference in time to render

(a small percentage increase/decrease in say a simpel scene rendering in one minute woul reuslt in seconds/fraciton of seconds differenc,e too small to calculue, so you need very slow rendering scenes for comparison tests)

Also, this scene has the wood planking material that shows off the anti-alising well

We've done weekend renders and 3 day renders in my studio.  The best thing I've done is to buy a intel i7 2700k.  It's the lowest price computer I've ever built (under $1500) and it's overclocked by 30%.  A render farm with these 2700k would rule the roost in terms of power and money efficiency.  The OC ability on these chips is FANTASTIC!

BTW a render measured in minutes is not  a long time, so it I deduce you have a fast computer.  Surrender to the render and have a cup of coffee you're doing fine.

I've got Maxwell renderer (now at verison2) which I use when modelling in Rhino, produces fantastic results as it's unbiased but even with V2 and jsut simple scenes compared ot a forest for exmaple, Maxwell is slooooow just like Vue is ;)

and yeah, holy crap has CPU power improved!! think first Bryce render I did on a Pentium I or II, which is probably not nearly as powerful as some of the mobile phones today, never mind PC CPUs! :P

Volumetric renders could take DAYS, I think one took a week, and that's at 800x600 and none of the fancier stuff we have now.
