Im actually looking it over now and im adding more visual tests so i can try to see exactly whats happening. My first couple versions had visual bone and mesh displays for individual bones dunno why i removed all that but i seem to have actually thrown it all out. So right now im re-writing it all.
I did notice I could load it into the assimp viewer. I can only guess that there may be something not accounted for in the calculation somewhere.
Ya i tried it in the assimp viewer last night and it worked perfectly unfortunately the .net nuget is like a year old so im hoping it is something with my code here.
Mesh1 and Spine3 together appear to have a cone segment attached which appears to me to be a bone visualization in the model editing program this annoys me the most cause it looks like something assimp should have purged on import. Spine3 here is also the neck area of mesh 0.
Ill post back soon as i get this visual debuging stuff re-written that way i can see the exact node chain transform were these messed up parts are to were they are not.
Should be able to at least visually identify what the problem is then exactly.
