BEPUphysics

I try to use utility to covert yaw pitch roll to quaternion.
Then I send it back to Unity.
It seem in Unity it is incorrect.
Are there ways to convert quaternion from Bepu to Unity.
Thanks.

Yaw/pitch/roll alone do not map to unique orientations. The result depends on a convention (axis order and such), and if that convention is different, the orientation will be different.

If you avoid euler angles, conversion should be more reliable.

thank you my brother already fix this.
