@gap and privateer:
Understood the concept. Thank for very good explanation. I assumed that something along those lines should exist, as it is basic concepts of inheritance and child objects.
Considering the comment in regard to limitations that we currently have with the gr2 files for every model hat we will be working on we will need to decide if we should be doing it dat or gr2 files based on what exactly we are looking from it: animations, ability to link/child it out, add properties.
We currently can do a lot with dats, but I'm still not sure how well the interlacing the dat and gr2 files could be. I know TDW, for example, was able to merge dat animated file on a gr2 model: his flag mod. So far in my attempts I was it able to achieve even that. And that is a simple repetitive animation.
But now I'm just thinking aloud. A little rumble.
Will continue working on the balloon tomorrow
