Definitely cool this 3D Xchange thing. Bets thing about it is that it lets you export with only the parts that you want to animate. Usually cars come with either no animatable parts, or a gazilion of them. It becomes overwhelming to try to find yourself in all that. With this you can get a clean, stripped down prop for any purpose you need.
Niiice! 

I'm playing around right now with Xchange and yes, OBJ always works, except that it always messes up the materials. Sometimes, even when it's just a simple color, like red, in iClone it'll show up white. But still usable.
Thanks

For the Japan car gotten from Renderosity I used the OBJ format provided (IOW, it was never in Daz to begin with).  They provide as Poser, VUE, OBJ and 3DS formats.

I don't have a lot of things from Renderosity for this reason -- they don't play well in Daz and thus I tend to avoid them in the first place.  So using the OBJs directly in XChange is just easier.  However, for other items (purchased direct from Daz) here are my OBJ settings:



However, as a general rule almost any OBJ export will work -- you don't need these settings (as indeed you don't have when you just use any OBJ imported from around the web).  The worst thing that will happen (and it does happen often) is the object is WAY too small for RL programs.  It will throw a warning, try to scale, but you will then need to rescale (no biggie, you just do it).  That's about the biggest issue you'll ever face on an OBJ import.

Thanks Mike. Can you please post a screenshot of your Daz export window? Below is a screenshot of what I used. I exported it in fbx. Going to try out in OBJ.

I'm not sure you mean it's a nightmare if you want to make all those props sub-props, or it's a problem when trying to scale, but if the former you don't HAVE to make something a sub-prop until you need to use it (as I say, you can always do this after the fact by just editing it further in XChange from iClone and then sending it back -- easy-peasy) and if the latter it should NOT have a problem scaling the entire prop and affecting those sub props (they will all scale with the main one).

Okay, I just tried it with the Japanese car and it worked fine -- I imported the OBJ (as shown in my video) and it all scales just fine.  I made sub-props of the door and wheels, imported it into iClone and, again, just fine (you can even scale the car there with no issues).  So I'm not sure where you're having problems but if you'd like I'll post another video showing how it works.

I tried it with those two cars since they didn't have a lot of sub props. I have cars with a gazillion subs, can't imagine the nightmare.

I tried it with "Japanese Car" which is a model of a Mitsubishi Lancer, and "German car", a model of a VW Golf. I bought them on Renderosity, don't know if you have them. See the picture. Something weird also, they don't have any sub props, but when I scale them, the parts scale separately.

Great video Mike! Much appreciated!

If you tell me exactly what prop you'd like me to try I can see what I can do (I have most Daz stuff).

Materials will need to be worked on, always.  My Blender auto routine does a really good job on FBX exports, but OBJs are another matter.  I'm looking at it right now to see if I can fix, but it might need to wait until we get Python inside of iClone (I'm hoping the process will be easier there -- it's a LOT of coding on the outside to do it).

Thanks Kelleytoons. There's still a bit of work to do but not that bad, I usually animate just a few parts. Too bad my demo expired a few days ago. Guess I'll have to fork the dough to test my stuff. I notice that the windows material is all messed up. Does it render ok? I had a few problems with materials too.
