msanandkumar Posted September 16, 2009 Share Posted September 16, 2009 I have a problem, with calculating light cache, when i start flythrough light cache calculation, it uses only 20 to 25% of CPU power . below more detail is given 0) Its a Quad Core Quad machine (AMD) at 2GHz 1) multithreading is on 2) displacement is off globally (used script to do this) 3) Interpolation is also off golbally 4) Machine is having 16GB of RAM 5) 3ds max 9 x64 is used 6) and Page file size goes upto 16GB 7) Dynamic memory is set to 8GB first then i changed it to 2GB still same probelm Can anyone suggest something to solve this problem...... this is a walkthrough project, huge area.... with lots of building and maximum trees (used instances). Dont know whats wrong with this...... please help. Thanks in advance.... Link to comment Share on other sites More sharing options...
Nic H Posted September 16, 2009 Share Posted September 16, 2009 er do you have 16 passes set in light cache rollout? Link to comment Share on other sites More sharing options...
msanandkumar Posted September 16, 2009 Author Share Posted September 16, 2009 Yes passes are set to 16......... but still problem exists. Please help me....... Link to comment Share on other sites More sharing options...
msanandkumar Posted September 17, 2009 Author Share Posted September 17, 2009 ok here is my screenshot............... I think while calculating also it should use 100% CPU Power.... Link to comment Share on other sites More sharing options...

Nic H Posted September 17, 2009 Share Posted September 17, 2009 ask on chaos if you have a legit version Link to comment Share on other sites More sharing options...
kippu Posted September 17, 2009 Share Posted September 17, 2009 have you tried taking all the instances off and trying it out? Link to comment Share on other sites More sharing options...
Tim Nelson Posted September 17, 2009 Share Posted September 17, 2009 Try increasing the dynamic memory limit. LC should use 100% cpu unless there is a memory limit/bottleneck. Link to comment Share on other sites More sharing options...
msanandkumar Posted September 17, 2009 Author Share Posted September 17, 2009 I tried by hiding instances, if i do that it is doing better, i mean light cache is building fast and usage also increases.... (not hundred percent) And i am using dynamic limit of 12 GB ...... dont know still its not using 100%.... only 20 to 25% its using. And about contacting Chaos is the last option then, or i should try adding some more RAM and then i will check once again. Link to comment Share on other sites More sharing options...
msanandkumar Posted September 17, 2009 Author Share Posted September 17, 2009 Light Cache calculation is over..... now. But it never used more than 30% CPU, but its complete so for now i will not think more about it, as i need to finish the animation. Will start irradiance map now Link to comment Share on other sites More sharing options...
Jimy Posted September 17, 2009 Share Posted September 17, 2009 You wanna be careful when setting that dynamic memory limit. We run servers with 4GB of RAM and the dynamic mem limit at 2500, or 2.5GB, otherwise it goes into virtual and slows. Anyway that's only really important if you have displacement on, which ya don't. I noticed in your screen shot that you have the light cache preview on. This sometimes causes the light cache to take ages for some reason; bug. Try turning this off and running it again and see if it speeds up? Link to comment Share on other sites More sharing options...
msanandkumar Posted September 18, 2009 Author Share Posted September 18, 2009 Hi Jim...... thanks for your suggestion will try that, as now its creating irradiance map, even now also its not using its full power, only using 215 to 20% Link to comment Share on other sites More sharing options...
