I need to convert some position and rotation data of skeleton nodes (in actor space) from Unreal to Babylon.js.

Unreal Has Z-axis as the UP vector as opposed to Babylon.js, which has Y-axis for the UP vector. I’m not super knowledgeable about quaternion math, so how would I go about converting the quaternion properly, given the quaternion X, Y, Z, and W values from Unreal?

Thanks in advance!
