OK here's another stupid newbie question...
I'm still very new to Carrara but eager to learn!
  
Why does a spline objects with a texture map wrapped around it take so long to update in the assemble room. An exact same vertex object with the same texture map wrapped around it is pretty much fully rendered and stays that way when you move, rotate and scale it but the spline object just goes black when you touch it and then renders about 2 seconds after. It's kind of irritating because it's nice to see the image map when you are posing it in the correct way for the camera!
We're talking about a basic cylinder with filled-in ends here people - I did say stupid newbie, didn't I.
A more complicated spline object take ages and ages to 'come back' - maybe 15 seconds or more.

Interactive render in this room set to Open GL, texture map 512 displaying texture, anti aliased, reflection & transparency all checked.

Is there any chance that it could me my graphics card - I have a Radeon 9550 128mb and that may not be enough!

Many thanks,
R

Oh, buy the way, everyone's talking about UV this and UV that, what exactly does UV stand for ??

well, a spline object normaly has more polys than a vertex object (but that can depend on the person doing the modeiling so that could be slowing things down a bit, my personal oppion is your going a bit extream on the preview settings, try removing one or two of those, my first sigestion would be anti al.

UV is a system for depecting a 3d object in a 2d way, defining where each poly is in relation to a space on a flat image so if polys overlap on a uv map you'll get all kinds of crazy stuff going on.
