#1 This sounds wonderful Jeff. Look forward to future postings on your progress :)

#2 These posts are on behalf of Mike Paixao, he is doing the work on this,

Unfortunately I am unable to give out the tool as it is in house only, but I can share my snippets of math equation for the proper ueler to quaternion

ive done most of the figuring out, it works on most angles up to a certain tolerance, then it explodes and deforms the shape in torque, when I get some time to put towards this Ill post either an update or the finished snippet

-Mike

#3 This is another post for Mike Paixao ( should really get an account of my own! :P )

heres what ive come up with, havnt had much time, its not perfect, but if you only rotate on 2 axes (wich can do all rotations...) and you set Maya's graph editor to Quaternion curves instead of Euler



note: I will finish this once I finish the exporter, although I cannot share the source,
I will try to get a plugin version out

as right now it exports LOD objects, exports all known flags, and creates a nice little data block you just cut and paste into the mission file...
working on rotation instance objects...




yes... I have alot of un-used variables... I know :P

#4 Another post for Mike Paixao ( any admins able to get Mike his own dev account? :P )

this one is short at sweet, a trick to make sure it works is to set a key on the object, make the curves in the graph editor Quaternion
do that with a simple script ( rotationInterpolation -convert quaternion objectNameHere_rotateX; ) this will convert XYZ to Quaternion

as far as this section goes, I just have to organize the X Y Z so it places it properly, wich im doing now and should be done shortly
