Sorry , Jason , its been a little while since I started messing with that file and I had only used it in ver 3.9 until this .I believe Duion is correct , I use blender and exported the DAE using the baked animations file . So this is from todays further look into it . As Jason suggested I checked the nodes in the shape editor .
I have a current source code so i looked and fount this
U32 TSShape::smMaxSkinBones = 70 ;
Some numbers from the dragon model ;
number of bones in Rig = 137
number of bones in feet = 66
so I deleted the 66 foot bones plus a few head bones and relaced the feet bones with
just 4 bones . this picture shows the result . just a little messed up though .
So , I guess its the bone limit then ?
