It's not something I can just set without consequences... the constraints in havok are sensitive to equalized large mass, which means the more equal and large the masses constrained the more rigid and powerful the constraint is, basically.


Someone had a similar issue in the comments.

This thing can lift fine, but if you fill the grinders with stone then it no longer can lift it.

Problem there is you're not increasing the mass of the top grid of the rotor but effectively pulling it while it has low mass (because other subgrids are more massive and gravity)

But if you place a heavy block on the piston grid (which is the top grid of the rotor) then the mass will be closer to equalization and it can lift it no problem.


The hinges have the exact same mass as vanilla rotors (which is determined by the components).

As additonal aid as I had the same issue, try artifical mass blocks on the opposite side, they add huge amounts of wieght which really helps equalize the conveyor
