chuck Posted February 20, 2007 Share Posted February 20, 2007 So my firm upgraded from Vray free to the lastest full version. Besides the bug with bitmaps missing when used with viz 2007, my scenes originally created with viz 2005 and vray free are running out of memory. Nothing has changed in the scene, is the full version just a memory hog? Currently I'm trying to turn down the raycaster settings, but stuff still crashes at high res (4k x 3k px). I have the 3gb switch enabled on my workstation which is a Dell dual xeon 3.4 with 2gb of ram. I spent most of my day adjusting stuff then coming back 30 min later to find errors. Most of my materials are standard since vray mats with textures won't render correctly, will that make a difference? My lighting setup is the same too, IR map, very low, with the same values all around. Thanks for any ideas... Chuck Link to comment Share on other sites More sharing options...
aaron-cds Posted February 20, 2007 Share Posted February 20, 2007 Why are you not using 1.5 rc3? 1.47 doesn't work with viz2007 without the known errors. They fixed those bugs with the latest version. Link to comment Share on other sites More sharing options...
chuck Posted February 20, 2007 Author Share Posted February 20, 2007 I wanted to go to 1.5, but our IT guy wouldn't. He won't install any release candidate software, even if it's perfect. Does 1.5 manage memory better or should I just continue tweaking? Thanks... Link to comment Share on other sites More sharing options...
manta Posted February 20, 2007 Share Posted February 20, 2007 How does your IT guy feel about moving up to X64, that will get rid of alot of memory problems... Link to comment Share on other sites More sharing options...
Tim Nelson Posted February 20, 2007 Share Posted February 20, 2007 Your IT guy doesn't do the rendering, YOU do. So you should tell him who's boss, stop playing d&d and install what you tell him to. Link to comment Share on other sites More sharing options...
aaron-cds Posted February 20, 2007 Share Posted February 20, 2007 I'm going to refrain from namecalling when it comes to your IT guy. If you trully can't use 1.5 then you need 1.46.15, which is the version that doesn't have problems with bitmaps with viz 2006 or 2007. Just email chaos group and they'll send it to you. They might laugh at your IT guy though sorry, I can't leave this alone. You're IT guy will set up a 3gb switch but he won't install 1.5 rc3. Besides, I thought Dell workstations don't allow the 3gb switch. That's what I read somewhere. Link to comment Share on other sites More sharing options...
Tim Nelson Posted February 20, 2007 Share Posted February 20, 2007 thought Dell workstations don't allow the 3gb switch. That's what I read somewhere. I don't think that's true, at least for some of the older machines. I was able to add the switch to the Dell's we have here. Link to comment Share on other sites More sharing options...

chuck Posted February 20, 2007 Author Share Posted February 20, 2007 Thanks for the replies... I haven't talked to him about x64. We just bought viz 2007 and vray, two licenses of each, so an upgrade to Max 9, more RAM, and a new OS will create problems. I could probably convince the partners it's where we'll need to go next, but I'd like to try to work with what I just had installed two weeks ago... We will probably move back to 1.46 for now. The 3gb switch worked fine on my dell. best IT quote I get around here: "why do we need all these workstations, we're not Fing ILM!" To him, powerfull workstations are Pentium D's with a gig of ram... Chuck Link to comment Share on other sites More sharing options...
aaron-cds Posted February 20, 2007 Share Posted February 20, 2007 You need to upgrade your IT guy first, then upgrade to max 9 64 bit with 1.5 Link to comment Share on other sites More sharing options...

Tim Nelson Posted February 20, 2007 Share Posted February 20, 2007 So, getting to the 1.47 issue. We still use 1.47 and it's been pretty good, although we are on Max8 not Viz. I think there are some big differences between Vray free & the full version, the biggest one I think being that there are no Vray materials in the free version. You'll want to start using only Vray materials but I don't know if that will help with memory at all. How big is the scene that you're working with? There are lots of tips & tricks to keeping memory down, so I'm sure you can get some help if you provide more details. Link to comment Share on other sites More sharing options...
aaron-cds Posted February 20, 2007 Share Posted February 20, 2007 The mapping problem only existed in viz. As far as memory goes, you should upgrade to 3 or 4 gb of ram to fully take advantage of the 3 gb switch. Link to comment Share on other sites More sharing options...
chuck Posted February 20, 2007 Author Share Posted February 20, 2007 As for the scene- Vertices: 3,339,643 Faces: 2,680,361 Does the type of secondary bounces change memory usage? The scene will crash with my xfrog trees turned off, but vray free handled the scene with them on. Thanks again for your help, Chuck Link to comment Share on other sites More sharing options...
Tim Nelson Posted February 20, 2007 Share Posted February 20, 2007 That is quite a high number. I'm not sure why vray free rendered it and not the full version. You might possibly have to convert the Xfrog trees into vray meshes. Probably most of those polys are in your trees and thats creating the memory problem.

gfa2 Posted February 20, 2007 Share Posted February 20, 2007 The scene will crash with my xfrog trees turned off, but vray free handled the scene with them on. Chuck I use Onyx trees and I almost always convert them to vray mesh or else it will crash. I did a highway scene with 17,000 trees in it with the vray mesh technique. Make sure you instance your trees after you convert them to vray mesh. Link to comment Share on other sites More sharing options...
