Hello Fabricio I have a same issue... Could you share a ice graph you mentioned as below. "problem solved:
I had to multiply the original particle rotation by the inverse of the rotation of the closest point on the emitter, then multiply the result back again to the actual (deformed) rotation of the closest point on the emitter."
