prateekvishwa Posted October 16, 2006 Share Posted October 16, 2006 there r so many reasons.. depends on ur scene setup 1) if u r using very high res. texture.. reduce there file size in photoshop and then use.. using very hires texture makes sftwre runin out of memory 2) if u r using caustics.. try rendering wthout caustics 3) if using light cache then check sample size..use screen n not world.. if world then try using sample s ize >1 4)if ir map.. try rendering scene wth low preset. best of luck prateek:) Link to comment Share on other sites More sharing options...
kippu Posted October 16, 2006 Share Posted October 16, 2006 well as the error msg suggests...you are running outta memory Link to comment Share on other sites More sharing options...
lambros Posted October 16, 2006 Share Posted October 16, 2006 I experienced same problems before, usually I just had to take hires images to photoshop and scale them down, as suggested. Having a 4K texture for wooden floor would just cause trouble if a 2K render with a partial view of the floor is what you are after. Jpgs may be small sized (in Kb terms) but they are decompressed once loaded and flood the system. Link to comment Share on other sites More sharing options...
manta Posted October 16, 2006 Share Posted October 16, 2006 Try using vray proxy's... Try using windows X64... Try using QMC instead of light cache... any or all should do the trick... Link to comment Share on other sites More sharing options...
chow choppe Posted October 16, 2006 Author Share Posted October 16, 2006 How to check which bitmap is causing problem because everytime each gives error for a different object with a different bitmap how to handle such a scene which has same copy of a villa x 300 times? I always used instance but instances also give this kind of memory error. Also copying things slow down the viewport even if i am using a 256 mb PCI express in my system Any suggestions Thanks Link to comment Share on other sites More sharing options...
chow choppe Posted October 16, 2006 Author Share Posted October 16, 2006 Try using vray proxy's... Try using windows X64... Try using QMC instead of light cache... any or all should do the trick... I am using QMC already using Vray proxy now after so much wrk and texturing is looking a bit difficult to me Is there any way by which , when converting the villa into a proxy object, it should automatically creat a multisubobject material on its own taking into account all the different materials that are applied to it. Will windows x 64 actually solve the problem? I know you mentioned this already on this forum but does it actually works? thanks Link to comment Share on other sites More sharing options...
manta Posted October 16, 2006 Share Posted October 16, 2006 Well check to see how much memory you are using while rendering, X64 will allow you to use 3.6GB before crashing... Link to comment Share on other sites More sharing options...
chow choppe Posted October 16, 2006 Author Share Posted October 16, 2006 will enabling the 3gb switch help? Link to comment Share on other sites More sharing options...
manta Posted October 16, 2006 Share Posted October 16, 2006 yes...it will probably let you go as high as 2.86GB's with Max... Link to comment Share on other sites More sharing options...
chow choppe Posted October 17, 2006 Author Share Posted October 17, 2006 and what if get my system ram increased from 2 GB to 4GB will that help? because money is not an issue right now to solve this problem Link to comment Share on other sites More sharing options...
manta Posted October 17, 2006 Share Posted October 17, 2006 and what if get my system ram increased from 2 GB to 4GB will that help? because money is not an issue right now to solve this problem Only if you use X64, windows XP will just ignore the extra ram... Are you having any luck with the proxies ? Link to comment Share on other sites More sharing options...
chow choppe Posted October 17, 2006 Author Share Posted October 17, 2006 why is that does win xp 32 bit doesn't support 4gb ram if i use win x 64 ...will max 8 and vray work fine in that and rest of my softwares also...i mean photoshop CS 2 , Auto cad 2004 or autocad 2007 I am not trying vray proxies as i mentioned i have already placed 300 villas on site i can't place 300 proxies again don't have that much time left with me....also it will take me more time to give object faces id's and apply materials as mutlisubobject material. Anyway i appreciate the effort u guys are putting in to help me thanks Link to comment Share on other sites More sharing options...
chow choppe Posted October 17, 2006 Author Share Posted October 17, 2006 now i am getting a new error some samping displacement error i have also installed x 64 now but still i am having same problem Thanks Link to comment Share on other sites More sharing options...
alfienoakes Posted October 17, 2006 Share Posted October 17, 2006 Maybe worth you having a look over on the chaosgroup forums as well. The guys here are all very good, and very helpfull, but chaosgroup is pretty much vray only, so always worth a look for more specific errors etc.. And Vlado is over there as well, who is pretty much Mr Vray... Andy Link to comment Share on other sites More sharing options...
alfienoakes Posted October 17, 2006 Share Posted October 17, 2006 Memory errors unhandled exceptions in Vray, are commenly caused by memory problems. Your last one seems typical of this, from chaosgroup help: Displacement mapping - objects displaced with the 2d displacement mapping method may require a lot of RAM to render, especially with large displacement maps. If this is the case, use the 3d displacement mapping method. Also, if you have several distinct displacement modifiers with the same displacement map, it is better to replace them with one modifier, applied to all the necessary objects. This is because each modifier will take RAM for the displacement map, separately from other modifiers, even if they have the same map.
