Hi WendyI'm sorry to say that if these are none standard character and no animation files have been given with them then I think I am right in saying you need to animate them bit by bit in the motion editor. This is not easy and as it is based on keyframes moving 2 joints at the same time is near impossible.
I have been asking for better animation tools for these characters for some time so waiting to see what Iclone 5 offers.
The best option you would have had would have been to buy the Daz version animate in what ever program you use then export as FBX Import into 3dexchange with animation. You need to keep the pollys down or 3dexchange will crash.
Ho and you would probably save some cach too ... I bought 3duniverse toon cars from RL $39 =£30 expecting Icars noooo! Over at Daz $19 = £11 and had to to the same amount of work on them to turn them into Icars .....
If it is important for RL to sell content then their content needs to stand out (some times it does) but of late $99 content sets with a handfull of props and little to no Iprops doesnt make sence..
Im just saying.............
