hello,
i have one arm mesh set in a particular position. and i have another arm mesh that shares the same topology but which has been sculpted differently and positioned/rotated elsewhere in 3d space.
What i want to do is subtract the translation/rotation of the second mesh so that it rests ontop of the first mesh and i can use them as blend shapes, so when i blend it just reveals the detail of the new sculpt and doesn’t move the mesh in space.
i thought i would find the average vert position of either end of both pieces of geo and find the vector of each piece, then find the angle between and rotate the points to align somehow. But i wanted to know if there is a way of somehow doing this with just maths rather than in 3d, storing the new aligned points in an array and using them as a morph target.
does this make any sense?
thanks,
Sam
