I've been working on setting up a really really simple scene in Cararra and for some reason it's slowing Carrara to an absolute crawl. I just finished a project that was 50 times as complicated and Carrara handled that one fine. In this scene I have 4 objects, 2 with pretty low polygon counts, and 2 with polygon counts that are on the high end of medium. I have basic Carrara shaders on 2 of the objects, both without any texture maps, and medium sized texture maps on the other 2. The lighting is pretty simple, and I have no effects in the scene. I am at a loss to figure out why my Carrara is being so slow. I even closed the project, rebooted, and opened it again, to find it being just as slow as before. Carrara is taking about a full minute to do anything I tell it. If I click in a checkbox it gets the checkmark a minute later. I also know it's not lack of memory (I have 256 megs) and it's not other programs eating resources, because I closed everything that was running. Any suggestions of things I could check to make Carrara not be so slow?

Once, i had a file that went very very big after an simple operation ( i was working with vertex ) , slowing down Carrara a lot . I took the previous save i had done and the file stayed little after that . If your file takes a few megaoctets although it is simple, then it could be the same problem . I hope you got a few saves of your work . If you don't, you could try to export your objects one by one, then reimport them in a new file . I hope that helps you .

I bet you there is a good chance you have physics turned on? I have accidently turned them on while working on a p3 500 with 512megs of ram...it about choked the thing.

oh my! I just looked at the file size on it and it's over 23 Megs!!! The original file I imported was 9 Megs, but it's not had a problem with imported meshes under 10 megs before.

I don't know if this helps but sometimes in raydream studio my meshes actually double themselves and I have to select the whole object and weld it back into a single mesh. You can't tell from looking at it because they ocupy the same space.

Mesh objects saved in Carrara tend to become bloated for some reason. If you save as wavefront from RDS at max and save the same file from CAR at max the resulting file is about 10 times the size as RDS with no apparent difference in quality.
