Sackrat: Thx for your generous offer, but I'm looking for something that can generate tree/bush .obj files or similar (much the way that Plant Studio does for flowering plants). Electroglyph: Will see what I can find at that link. Pakled: I don't have much in the way of trees to shrink in the 1st place, alas. Mrdodobird: Probably NOT a good idea in the Oval Office:-) Gog_CA1: errm, same prioblem as with Pakled's suggestion... Thanks to all for the replies. Something may turn up if I keep looking hard enough. Cheers, Diolma
