Hi CrystalDragon, A few tips that will speed up FireFly rendering times and lower memory use: 1. Render Options. Uncheck Use texture filtering. Texture filtering reduces texture antialiasing but because summed area tables are used with texture filtering, memory use can increase up to four times. When I rendered the UD Hydra figure which uses a 5000x5000 hi res texture, my system was swapping VM like crazy. I recommend not to use texture filtering on scenes that have high res textures. I rarely use that option any more. I think Larry turned it off on default settings now. 2. Render Options. Bucket size. What is your bucket size set at? The 'bucket' size is the size of the square that draws during render. The larger the square is, the more memory it requires, but in some cases will speed up the render time. I did get a render to stop when my bucket size was set to 76 (which takes up more system resources)and did a test at 6000x6000 72 dpi. After that I set my bucket size back to 32. 6000x6000 was too much for my system to handle. I recommend leaving the bucket size to 32 or marginally higher. For more information on this please refer to my post here: http://www.renderosity.com/messages.ez?ForumID=12440&Form.ShowMessage=959059&Reply=960669#11 Here a portion of the FF render at 1200 by 900, 300 dpi 3. You may need to increase your virtual memory settings. I've been able to render out my UD Hydra test scene 3000 by 2250 at 72 dpi and 1200 by 900 at 300 dpi. My system chunked away but I was able to render out the scenes. Again, turning off Use texture filtering dramatically helps reduce memory swapping. 4. Delete temporary files. An issue in a previous beta Service Release caused Poser to not delete certain temporary files. This issue has been resolved in Service Release 2.1 for Poser 5 (SR-2.1). There were two separate issues: - In SR2.1 engineering fixed a PBxxx.tmp file problem. It was a simple missing call to delete the PBxxx temp files. If you have residual PBxxx.tmp files, please go to the Windows/TEMP folder or Documents or SettingsUsernameLocal SettingsTemp folder and delete all of the PBxxx.tmp files. - Shadow map .tmp files. What will happen now is Shadow map .tmp files will be temporarily stored in the root of the Poser 5 folder during a FireFly render. Once a single scene or movie render is completed, they will be removed. The files will also be removed if the render is canceled by the user or if the render fails. Please reference the SR2.1 read me on this issue. Hopes this helps, -DefaultGuy
