Yea we can do some interesting stuff with the tool now. Not only can we mix and match parts of models from our dinosaurs into new creatures, but SynchroLight(creator and genius of the video) has showed us that we can use models from ZT2 and rig them to the skeleton of a JPOG dinosaur or animal. We can even do the same with models made completely from scratch.
So while the ZT2 community imported our models back then, we'd be able to import theirs to JPOG (with permission from the creators and using the right armatures of course). Or you could make your own dinosaur model and rig it to the armature of a species in JPOG
