Hi there I’ve been trying to get my hands on the rope lift tutorial for a while now but it seems to have disappeared from the internet completely nothing but broken links and blank pages so I was wondering if anyone could explain to me how to lift a box using the reactor rope and a rotating cylinder were the rope raps around the cylinder as it rotates.

It’s pretty simple, here’s the steps I used:

1) Create a box with a cylinder above it and put them both in a rigid body collection.
2) Create your line for your rope which connects the box and cylinder making sure you have a lot of segments.
3) Put a reactor Rope modifier on your line, adjust the thickness and change the rope type to Constraint.
4) Add two Attach To Rigid Body constraints.
5) Enter vertex sub-object mode for the reactor Rope modifier, select the first Attach To Rigid Body constraint, select the top vertex, and choose the cylinder as the Rigid Body to attach to.
6) Do the same as step 5 for the bottom vertex and using the box.
7) Create a Rope Collection with the line in it.
8) Animate the cylinder rotating and set it to be Unyielding in the Rigid Body Properties and give the box a mass that’s light enough for the rope to lift it.
9) Run the Preview Animation and watch.

If the attachment went through, it’s a Max 2009 scene with an example.

Ok thanks allot I will try that, I can see from what you explained there that I missed some crucial steps when I attempted to do it based of what I had seen in video demonstrations.
Hopefully my next attempt will prove successful and thanks again :)

I still carnt get this to work i have the same problem i had earlier just when the rope is beginning to lift the box of the ground the rope cuts through the cylinder instead of rapping around it I even created the exact same setup in the example file but I still get the same problem dose anyone know what could be going wrong?

I’ve tried messing with the mass on everything and the rope still doesn’t coil around the cylinder although I have succeeded on one setup were I created a setup next to the one in the attachment only to be faced with the same problem until I moved the cylinder very close to the rope so they were just touching and it picked up in the simulation but I can’t seem to re create this in a separate scene, are there any other factors involved when setting this kinda thing up?

Can you post your scene so I can look through it?

fingers crossed

I got it working by adding some distance between the rope and the cylinder, then lowering the reactor Collision Tolerance to something like 1/2” (Utilities\reactor\Havok World). The interpenetration of the rope and the cylinder before the sim made it ignore the cylinder, causing it not to rap around it.
