Hi Nicolas, You need to use a source and target solution. The source has the simulation on it and the null deformers are constrained to it; think of the source as if it were a rig. The nulls in turn deform a second mesh, the target which is point weighted. The target and its deforming nulls are what is exported to the game engine.
