Hi Dr Max. I can only answer 1 of those questions (and that answer is a direct quote from Dr Geep - I can take no credit) regarding hard+soft vertices: 1. Split all the vertices. 2. Then make a group and include the ones you want to have soft edges and make a New Prop "A"(soft). Export this and then import it with "Weld..." checked. Now this group will have "soft" edges. 3. Also, make a New Prop "B" (hard) for the rest of the object excluding the group that you used in #2. 4. Export both New Props "A" (soft) and "B" (hard) and then import it with "Weld ..." UNchecked. Note - If you UNcheck everything (except "Weld..." if required) when you import, the object will remain the same size and stay in exactly the same position as it was when you exported it. Hope that helps some:-) BTW - if you also repost this in the main Poser forum you'll probably get a lot more help, from those who are far more knowledgeable than I am. VERY imposing hallway, btw.. Cheers, Diolma
