Mark -- I only have Photoshop Elements (which doesn't deal with paths) and Uleads PhotoImpact (which does do paths), so I tried this in Ulead and got the following results.  Yuch! First off, it seems my scale is wrong.  My original terrain texture I exported was 2049 x 2049 (and still was when it came back, as well as the alpha and tex maps).  My World size in Carrara is 1000 x 1000.   I want to scale this to allow me closeups of the car on the road without the fuzzy edges and lines on the roads.  Where is my scaling off? Also, the 'terracing' effect you mentioned in the video is occuring, even though I'm keeping the Terrain Editor window open the entire time I work on the road, alpha and texture maps...and then immediately import them back into Carrara. Do you think its a Ulead problem?
