For the appearance attribute of the shape using textures with transparencies, you may need to add TransparencyAttributes with value=0 and mode=BLENDED.Cheers, Florin -----Ursprüngliche Nachricht----- Von: Lan Wu-Cavener [mailto:[EMAIL PROTECTED]] Gesendet: Donnerstag, 30.

I tried RGBA, and a more "full" tree image, I got the space between the foliage black instead of white. Does that mean that the image background part stapled to the geometry will not be transparent? >In order to look more realistic, then you really need to have a little more >complex geometry for the "green" part, and use dot3 bump mapping for the >trunk. >Do you mean that I need to create geometry in a similar shape as the tree >shape in image? Could you please explain a little bit more? My geometry for the tree is editable by user which limited the degree to customized the geometry to the image tree shape. Thanks again!
