Architecture - vray

[Gerbilho]

I modeled a few buildings and a garden. When I render with vray, specially with larger images (2560x1920) I get some strange colored spots in some areas of te image. I guess vray doesn't do well with "heavy" scenes. How can I solve this problem? I need help. Thanks

wow man, nice tree, is that treemaker? or a maxscript or something? nice textures, cant help you with your problem hough. sorry

try higer settings

[BigDawgXY]

that is wierd but the only thing i can say is overlapping meshes in brazil this makes spots and such but not in colors like that. i think it needs more passes as said by EF_studios.

is any of this textured or is that just shadow errors under those fence things? If theyre errors then i agree that you would probably have to use some higher settings. the modelling is looking good however, that trees looks very real. Looks like somone went paintballing

[Gerbilho]

Ok. I found the problem! I had overlapping meshes. I fixed it and now the spots are gone. BUT!... I still have another problem. I have to render this image (I posted just a portion of it) in a real big size. But when I try to do so max crashes. Is it normal? I tryed 7680 x 5760 and it crashes, I tryed 6500 x 4876 and it went out of memory and crashed (I have 512 mb Ram). Is there better way of rendering big scenes even if it takes longer? Is there a way of rendering only a part of the image at a time to sva resources.... please help...
And here is the unfinished work...

sorry gerbilho, i dont know how to help. The only way i can think of that would take a very long time and probably not even work well is to place a bunch of cameras in the scene, and have the height dimension the same, but the width you would split up in say, 6 or 8 different parts or something, then piece it together in photoshop. (very bad idea lol) It seems like it is a ram problem though. sorry =/ it looks great though, may i ask what youre rendering it for?

hey mate...not bad.......I would suggest rendering out portion a a time...say break it up into 9 pieces and render it out, then use photoshop or the like to stich them together....using the same lighting etc all you have to make sure is that your camera ispositioned in the same location but pointed in a diffeent direction.

Let us know what you come up with.......them again you could just go out and buy some more ram.

[Chokin Hazard™]

Yeah same here I cant render images more than 3000 pixels in 3Ds Max

[novoAlias]

just get more ram =/

nice buildings btw :D

[Dridon]

Wow man this is a really cool architecture ;)

what you could do is take it to a render farm, i have seen some ads for these in 3d magazines, they charge only a few dollars per computer per hour, and i think they would probably be able to handle your problem. hope it works out

[3dway]

The latest issue of 3dworld magazine has a big tutorial on multipass rendering.

Same idea as stated here. render it in layer and composite them in combustion, aftereffects, or photoshop.

Not sure about all of those software names. I'm sure you can do something in photoshop.

Here is an update.

[Gerbilho]

Although I'm an architect, I'm just doing this 3d for advertising. The architecture was made by a friend of mine, we used to work together. One of these buildings is already being built. The client wants to promote this as soon as possible. He wants to make a large poster 8 x 6 meters...it's huge. That's why I needed a big image...

[Ferry P]

just make a couple of blowup renders...and put them together in PS.
make sure every render selection is the same size.

the size of each blowup render can be as large as your pc can handle...so if you split your scene up in 10 regions and each render is like 4000 x 4000 you will have a mega resolution render if all combined.

good luck

[Gerbilho]

Yes that seems great but how do I split the render in regions?

[Gerbilho]

anybody?

i have the same problem with brazil where if i spec too high a render output it crashes. it must have something to do with plugin renderers and max render output. it cant be memory. i have 1 gig of memory on my pc. it has to be something else other than memory. so far your best bet seems to be either sending your work to a render farm or contacting vray for an explanation of what to do exactly with this situation. im sure they'd have the answer there. let me know when you do resolve this. be nice to find out how to get past that.
