Hmmm... no idea on that one offhand. As far as I recall it's always kept the bits in place for me. If you want to (and legally can) you could send a .OBJ in my direction and I'll try and check it out. I'd say a C4D file, but I'm waaaay back on V6. Cheers, Cliff PS yup just tried it here and the spawning produced "props" in exactly the same place as the original - no movement I can detect at all. I'm guessing it's something to do with the .OBJ file Cinema4D is producing but offhand... :(
