i was trying to get the new and improved phoenix space superiority fighter with its totally insane variable geometry multihinged wings. i was wondering that the max submodel heirarchy depth is? you see each wings are made of 7 subobjects, the first segment is the child of the ship as well as the parent for the second segment, which is parent for the third and so on through all 7 segments. this is all set up for the purpouse of using the submodel animation code. each segment needs to inherit its parents motion.

anyway i plugged the ship in for a quick test to see if the engine can hack the model. the lab rendered it just fine, even the cockpit windows worked, i was amazed so i try a mission, ship renders ok in the interface. game crashes as soon as i hit commit. the ship also seems to crash fred. i ran it throiugh a debug build, it gets to the tech room where i immediately get a crash, the tail end of the log goes a little something like this:

it seems to not have liked this models depth of heirarchy. so did i hit an inpenertable barrier of stupidity, or is there hope that my model will one day work?

edit, by the way im using the fs2_open_367_p4.exe/fs2_open_367_p4_d.exe

edit again, yup, its the heirarchy, i broke it down and recompiled and the ship functions nicely, fairly stable too. any chance we can get more depth in our heirarchy?

Probably.  This is worth doing.

I don't know the first thing about how one would fix that, though.

the max instance depth used by the model rendering code is 5.  The define in question is MAX_SUBMODEL_INSTANCE_DEPTH or something similar.

i dont see anyone using more than 1o instances of depth, i dont plan to use more than 8 myself. might want to ask the starfox guys though, they might have some fancy animations planed, other mods as well..
