Today I've added some RAM to my system and it seems to work a lot better. Although it seems the renderer of Poser can't handle complex scenes (about 2-3 million polygon's). I really hope this will be fixed in the next servicepack. @Tastiger, I've tested a V3 character with DM's Alina morphs & high res textures equiped with Egypt Hair on the same scene I had a Daz Hires Skeleton (based on M3) with P6 Dynamic hair) and I was able to render it with the settings: resolution: 1600x1200 cast shadows: on ray trace: on ray trace bounces: 1 min shading rate: 0.2 pixel samples: 4 max texture size: 4096 bucket size: 32 smooth polys: on Although I have to admit, the first 2 times the rendering progress bar was still at 0 after an hour or 2 so I figured it crashed. Thnx guys for the feedback. Although 2GB still won't solve every memory issue, I've learned that more than 2GB isn't necessary for Poser since it can only allocate 2GB. I've upgraded my system and am pleased to say it works a lot better!
