rendering time problem - PLEASE HELP!!

[cocolas]

ok guys, this is an interior of a gift shop I'm working on - still a WIP.

the problem I'm having is very high - unusual render times:
for a 2000 wide still it took 19 HOURS to render on a dual Athlon mp 1900+ w/ 2 gigs of ram.....waaaaay to long so I'd like to figure out why and reduce that.
the scene is pretty small only - 46,000 polys.
I have about 25 lights in the scene (all spots) and a couple geomentry lights (thin cylinders w/ a standard mat w/ and output map in the selfillumination channel - wrapped in a vraywrapper w/ GI generate set to 10).
I also have those filleted columns (the fillet was booleaned out w/ thin rectangles) -

so at first I thought that was the problem, because i thought the filleting was traping light rays - so I substitute them w/ simple boxes - but it's still taking long time.
I also tried to hide the light objects (I know they usually add to render time) - still taking long...
I tried to render it at 640x480 w/ imap settings to min/max -4/-1 (the only difference between the high settings posted below for the 2000 pixel wide)....and it's still taking about 1 to 1 and 1/2 hours to calc the imap.

btw, the only reflections are in the table/counter tops marble and they are not blurry, just straight.

do you think that filleted columns contribute much to these high render times?? if so, what could be a solution?? - they need to stay since the client wants them in.

any way, here's the pic...

and here's the vray settings for the 2000 wide - with object lights and filleted columns...

and a max screen shot:

any help would be GREATLY appreciated!!!

thanks,

paul.

EDIT: I also use f-edge plugin by chaos to round off the edges of the counter you see upfrount and round display tables in the middle - I don't knof if that's cousing it....

Are those glass shelves? Are they refracting? Try not. Transparency? Try not.
Do the lights have fallof? Try some. Bump channel used? Try not.

I like the the render and, yes those times don't seem right! That scene should not take longer than 20 minutes to render.

do u hv anything else there with reflections? or refractions? besides the marble countertop? or the glass shelves? try to to turn them off to see if that will speed up ur renderign time. If this is for a still shot. u can probably use a max material instead...rather than a Vray reflection...reflect/refract takes forever.

[cocolas]

first, thank for the reply:

achin - i tried turning off reflections all together - and the times have gone done a bit - but it's stilll takin a long time (maybe 1 hour to 1 and 1/2 hours for the 1map for a 640x480 w/ min/max at -4/-1)

chicoone -
the lights have falloff and attenuation but I never had problems w/ that.

anyway - I don't know what else, so here's the file and maps - I also included the demo of f-edge plug (put in your "plugins" directory if you don't have it - or don't worry about it)
the file is heavy - about 10MBs w/ maps included:

please let me know if you try it and get results - thanks!!

PS: the redering in the scene is set to 2000 wide - you can reset it to 640x480 and adjust the min/max if the imap accordingly..

[marklazaro]

dont want to seem negative but you could use 3dsmax 5 or viz radiosity to calculate indirect lighting and on your machine it should not take more that 30 min for the full solution.

my point is you would achieve the same quality only in a fraction of the time.

If you want to make your render look like say those of Goncalo's youll need to ask his help.

thanks but no thanks.
my point is trying to improve constatly - that's why I'm usung vray in first place.....I'd appreciate if you had some constructive help, otherwise....don't bother.

don't get me wrong - all I meant is that I'd like some critism that would help me improve what I have with vray rather then just pick up and go use something else like max radiosity. that's all. didn't mean to come off the wrong tangent.

pls pray to ur processors to perform faster

[cocolas]

pls pray to ur processors to perform faster

I will - I'll pray to the cpu Gods to go faster!!!!...hehehe.....I'll have to make up a rendering dance to please the rendering GODS......

anyway - I've been rendering in an addictive mode- started w/ just the walls/floor/ceiling - and progressively add small piece back in the scene and render - so I got most pieces back (glass shelfs missing still) and I've been getting about 16 min renderings for a 640x480 w/out AA....
which is better then over 2 hours from before w/ the same res....will see, hopefully I'll find the coulprit...

[tanveer]

u are very funny.

pls post the coulprit's name . i will through him to the lions.

[chicoone]

Cocolas,

Can you post the scene in Max 4 format? This sounds like a good challenge, to explore speed tweaks. I only have Viz 4. Who knows? Maybe we can get under 3 minutes.

Ismael

[jujubee]

are you using bump maps for that pleated wood geometry or are they actual polygons? that's what would be killing your scene...

[robing]

hi cocolas,

this is a try @ 800x600 /-4 -1
I rebuild the complete ligthing and some materials.

[cocolas]

damn, looks nice robing....

and only 40 minutes....

I found out the glass seemed to be the problem as I had it - maybe the material??

can you repost the scene and/or tell me what you changed material/lighting wise???

thanks again for taking a stab at it - that's a much more manageble time.
did you get rid of the object lights (thin cylinders) under the arcades??

paul.
