Good day 
I used to use version 7 some time back and had a free .obj export plugin - this exported fine with materials in place. I uninstalled because there were too many issues rendering in Carrara.
I've now installed the free version 8, hoping for some improvement. Tried four different .obj exporters, none of which worked, so they must be out of date.
Tried the .dae export, but this does not retain groups or materials. It either crashed or did nothing in Blender, Vue, Daz Studio, Bryce and Carrara. I was able to open and convert to both .obj and .dxf, which worked fine, except no materials or groups.
Even tried sending to Babel3d.com for online conversion - it came back with groups in the hundreds, but with parts missing and no materials.
Would very much appreciate it if someone could give some advice on how to get a model, grouped and with materials, into a format usable for rendering in Carrara.
