I'm going nuts! I've done this before with no problem. I don't understand what's wrong now. I've exported a relatively complicated OBJ from Poser 5. 3 figures, a prop temple and some accessory figures attached (i.e. clothes and hair). I've taken the obj through Grouper to match up the texture maps. Then I import the OBJ into a Carrera scene and when I try to save I get the "An unknown error has occurred during save". Let's see, what other information might help? Carrera 2.1, just updated. Windows XP. 1GB of RAM. 1.4 AMD. My swap drive for Carrera is 4 GB alone and my Windows pf is on a 100GB hard drive. Any ideas?
