The texture spool is at the default setting of 1gb and 34+GB free on the scratch disk.  I let WinXP Pro manage the paging file.  But that's in my case.  I can't say what MatCreator's system is doing.  There doesn't appear to be anything heavy going on with the texture on the infinite plane.   2 texture maps are being used for the color and bump.  I did notice that texture #1 was tiling, while texture 2 was tiling and seemless.  Unfortunately, setting them both to tile and seemless didn't help.  The texture maps are both 1200x1200 which doesn't seem unusually large.  The whole scene appears to be pretty simple.  But then, I'm no expert at Carrara.  I only dink around with it now and then.  :)
