Looks very beautiful and the glass objects are very convincing ! Nothing bad to say :-) As Varian said you can use bitmaps for bumps. You can use color images (sometimes the same you used for the material) or grey scale images. In the BUMP tab of your material editor, right-click in the bump production window and choose "EDIT FUNCTION" from the list. In the bnew window, click at MAPPED VALUES and choose the file you want to use. Click OK and again OK. And if you want to save your bitmap as afunction file, just save it. Again right-click in the bump edition window and choose "SAVE FUNCTION". :-)Guitta
