Billabong Posted February 16, 2008 Share Posted February 16, 2008 and yet another problem. Whenever I try to render, Max will instantly crash, doents even go though any calcualtions what so ever. I hit render and it crashes. I'm using direct3D, but I also tried openGL, it crashed to. Here are my settings. comp: Quadcore 2.4 8 gigs of RAM 8800GTX(Just updated the driver when the crashing started, so that didnt help either) 3Ds max 2008 Vray1.5 scene settings poly count 525,649 2 palms using treestorm about 600 plants all made into proxies. also using the vray displacemnt modifier Frame buffer is disabled Adaptive QMC primary bounce is Irradiance map second is light cache IM settings Medium 20 20 LC settings 1000 .01 passes4 color mapping is Reinhard Dynamic memory is on 3200 default gemoetry is Dynamic. I really appreciate any help, this is driving me crazy Link to comment Share on other sites More sharing options...
Ricardo Eloy Posted February 16, 2008 Share Posted February 16, 2008 At what resolution are you rendering? This sounds like e memory issue. Try rendering a vrimg file instead of using the frame buffer. Link to comment Share on other sites More sharing options...
Billabong Posted February 16, 2008 Author Share Posted February 16, 2008 Hey Rick, I'm not using the frame buffer,I'm wondering if the the IM may have something to do with it. I may try switching to QMC. Seems like I read somewhere that IM and exterior rendering didnt go that well together. thanks for replying Link to comment Share on other sites More sharing options...
Crazy Homeless Guy Posted February 16, 2008 Share Posted February 16, 2008 I typically use a Irradiance Map, and Lightcache, or an Irradiance Map and QMC regardless of whether it is interior or exterior. I have actually had more problem with Lightcahce causing crashes than I have had with IM causing crashes. - Turn off displacement. Does it crash then? - Try moving your camera slightly. Does it crash then? - Turn off secondary bounce all together. Does it crash then? - Turn off all proxies. Does it crash then? ....if none of those do it, try turning on the top 4 or so layers, and render. Does it crrash then? ...work your way through the layer list in this fashioon. Often you can isolate a problem on a layer that is causing crashes, then you can work only with that layer to figure out the problem. Link to comment Share on other sites More sharing options...
Ricardo Eloy Posted February 16, 2008 Share Posted February 16, 2008 I insist. If Max is crashing as soon as you hit render, than the problem has nothing to do with VRay's calcs. Everytime you render something, Max kind of makes a copy of your scene and places it in your RAM. That happens even before VRay can start anything, and is what really causes most crashes (that's why using VRay Proxies is so good). Max's regular frame buffer (aka render frame window) is another thing that eats up your RAM as well, so you better use VRays VFB with the "render to memory frame buffer" option off and Max's FB at a very low size (4 by 3 is a nice one). This will prevent Max from allocating unnecessary RAM for displaying the rendered picture (meaning no crash). About the GI method you chose, it doesn't matter which one you're using. Like Travis, I also use mostly IrrMap+LC, regardless the kind of scene. Of course, each method has its advantages/disvantages, but that depends on geometry and it being or not an animation (VRay can't tell interiors from exteriors). And, just to make clear, your graphic card is not causing the crash, since it has nothing to do with the rendering calculations. Link to comment Share on other sites More sharing options...
Billabong Posted February 16, 2008 Author Share Posted February 16, 2008 Guys I really appreciate you helping, I'm gonna work throught it and see what i can from you guys have told me so far. May take awhile, but I'll post an update. Thanks so much again Link to comment Share on other sites More sharing options...
Crazy Homeless Guy Posted February 16, 2008 Share Posted February 16, 2008 also, if it crashing regardless of resolution, as Rick asked above? Link to comment Share on other sites More sharing options...
Billabong Posted February 16, 2008 Author Share Posted February 16, 2008 well right now im rendering at 640x480 and the one thing I have noticed is that max will allow me to render the scene one time, but if I try to rerender it, then it crashes Link to comment Share on other sites More sharing options...
Crazy Homeless Guy Posted February 16, 2008 Share Posted February 16, 2008 Are you using the 64bit versionof 2008? Right now, I am leaning towards displacement as the problem. Link to comment Share on other sites More sharing options...
Billabong Posted February 16, 2008 Author Share Posted February 16, 2008 yeah im using 64 bit 2008, ill turn off the vray displacemnt modifiers and see what happens. Thanks again Link to comment Share on other sites More sharing options...
Billabong Posted February 17, 2008 Author Share Posted February 17, 2008 well its not my displacement, on to something else Link to comment Share on other sites More sharing options...
WAcky Posted February 17, 2008 Share Posted February 17, 2008 well right now im rendering at 640x480 and the one thing I have noticed is that max will allow me to render the scene one time, but if I try to rerender it, then it crashes I think ricardo might have hit the nail on the head. Sounds like when max is done and you want to re-render max hasn't purged the memory yet and its trying to stuff more and more into your ram. One of the new webinars has a great tip in it, which is: whenever you're doing a large render, always reboot so your ram is as free as possible before you do your render.

Billabong Posted February 17, 2008 Author Share Posted February 17, 2008 well it looks like Rick was right, as soon as I switched to vrimg, not one crash. don't know what i would do without you guys, thanks so much to all who tried to help Link to comment Share on other sites More sharing options...
Billabong Posted February 17, 2008 Author Share Posted February 17, 2008 well, looks like I spoke to soon. Now its just crashing whenever it feels like it. on renders,changing viewports, basically whenever it wants. God, Max sure can be buggy as hell sometimes 2hrs later: I think i found out what it was, I have two onyx palm trees in my scene that are still in treestorm form, I deleted the two palms and it hasnt crashed yet. guess Ill have to call Onyx Mon. if that is the problem, I guess I could always just convert them to an editble poly and turn 'em into a proxy Link to comment Share on other sites More sharing options...
Ricardo Eloy Posted February 17, 2008 Share Posted February 17, 2008 I guess I could always just convert them to an editble poly and turn 'em into a proxy Which is what most of us do, anyway... Link to comment Share on other sites More sharing options...

IceAged Posted February 17, 2008 Share Posted February 17, 2008 God, Max sure can be buggy as hell sometimes It may be buggy, but it's not that buggy! Download MemTest86, and run it from a floppy disk. You'll get a pretty quick idea from this if there is a problem with your RAM. If something comes up, remove the offending module/s, (with the power off and unplugged), until you get a positive result with MemTest. http://www.memtest.org/ Link to comment Share on other sites More sharing options...
