Bones' roll values

Post by kostya_z »

Hello,
I have a model of a hand initially created in Blender 2.37a. Now when I open it with Blender 2.41 it has different roll values for every bone than before. Is it normal? If not, how do I retrieve the old values? Both ARMATURESPACE and BONESPACE are different from the previous value, I checked.

Thank you.

I was told that bones' roll values seem to be rotated 90 degrees counter clockwise. Why is that? Does anybody know?

Hello,
I am trying to fix an exporter for cal3d and therefore need some HELP!!!
Can anybody tell me, please, what's wrong with bone matrices compared to Blender 2.37a? When I export the model and turn off the animation it looks OK, but when I start the animation everything is twisted seems like 180 degree, or maybe 90, I can't estimate correctly, but I was told it's 90.
What's wrong with that stuff?

could you post a blend to the bug tracker?

that shows the bones and prints there values?


Thanks,

Ok, I did it!

Thank you for replying!
It's interesting that by multiplying BONESPACE and ARMATURESPACE values in treat_bone function I can get the model to behave pretty much the same, though ROTATION values in exported files are still different, of course.

Thank you!
