3DS Max Reactor Rope Issue

[joeburns]

I'm trying to create a pulley system and am having 2 issues:

1. I'm successful connecting my rope to a crane or pole at one end. When I try to connect to something on the other end, I get an error that I can't create a circular reference. To my knowledge, I'm not trying to create one. I'm following the directions from a tutorial that, unfortunately, was created under an old version of 3DS Max. However, that being said, I'm selecting the vertices that are inside my sphere at the end of the rope. When I try to assign them to the rigid body, I get the error message.
   
2. I have a block & tackle system. The top and bottom both have 2 pulleys. My rope weaves through the two pulley systems and is connected to a rigid body at the end of the rope. I want to pull the other end of the rope and have the bottom block slide up the ropes toward the top. How do I have the rope slide through the pulleys and make the pulleys come together (the top is fixed to the ceiling).
   

Thank you,

Can you post a link to the tutorial and a screenshot of your model?

[joeburns]

Here's the link:

Here's the JPG rendered frame. Hopefully it comes out OK for you.

So, have you figured it out yet?

Sorry, but animation just really isn't my thing, and I don't have any real desire to learn it.

I was hoping someone else would come along and point you in the right direction, but I guess not?

 

Did you follow the tutorial precisely?

Are you sure you didn't miss any of the steps?

 

My advice would be to just start over again from the beginning and make sure you follow every step precisely. Then, if you still have the same problem, maybe that tutorial is no good.

[joeburns]

No, I haven't figured it out yet. I have followed the instructions about 15 times and keep having the same problem. I've even tried to vary the scenario using other tutorials on the "reactor rope" modifier.

[Cad64]

Ok, I guess I'll give it a try when I get home then.

You're on 2011 correct? And you said you've gone through the tutorial 15 times? Can you tell me where you found the "reactor AttachToRB" modifier?

 

I have reactor Cloth, reactor Rope and reactor SoftBody, but no reactor AttachToRB.

[joeburns]

I thought I had replied to this. I guess not.

 

I am on 2011. The "15 times" may be a slight exaggeration, but I have done the steps multiple times - from the top and with any possible changes that I could think of.

 

Attach and expand the "Reactor Rope" modifier. Choose "vertex" and select the verticies that are within the object that you want to constrain the rope to - in this case, the 2 to 4 verticies that are within the ball. Scroll down to the "Constraints" rollout and click on "Attach to Rigid Body". This will put the "Attach To RigidBody" constraint into the list. Click that and you'll see a rollout above the "Constraints" one titled "Attach To RigidBody". Click the button in there and choose the rigid body object to constrain the verticies to. When I do these steps to attach the rope to the crane, everything is fine. When I do this to attach the rope to the ball, I get my circular reference error.

i think the ball has to be with a rigid body collection or different reactor collection

[joeburns]

I guess that I should have posted that I figured this out. Now I've progressed to the next step. I have the wrecking ball working perfectly. I believe that I had to remove the constraints on the objects that are outside of the reactor controls. Te ball now swings perfectly as the crane swings.

 

I'll start another thread with my new issue - a block & tackle where the control pulley pulls on the cable which raises the lower part of the b&t to raise up to the top block. This is how cranes at docks work. The lower block would be attached to the object to be lifted. As teh pulley cranks, the object is raised off the ground.
