[rotation] I grab vertex positions of characters hand during FBX animation, how can I rotate weapon so it always stays rotated relative to chars hand? Whatever I do I always end with implementation that either ignores hand’s rotation during animation, or ignores characters rotation when rotated on…

Problem solved, here’s the working code // function taken from https://stackoverflow.com/questions/31620194/how-to-calculate-transformed-skin-vertices // used to return positions of vertices from hero during animation const transformedSkinVertex = (skin, index) => { let skinIndices = (new THREE…

You can create a CS from the chosen points (-x, +x, -y, +y), see cs function.
Then you create a quaternion that rotates a mesh from world to the constructed CS, see csQuatern.
After that you can align meshes to that CS by assigning their quaternion to the one in the previous step.
