Hello there!

I’ve been trying to work with the ragdoll and rigidbody features. I have followed the tutorials provided by MB, but I am not getting the expected results. I’ve gone through the other discussions on ragdoll and tried doing everything that’s been suggested but its still not no good. Is there something critical that I’m missing?  There are two others who have tried the same independently and are having the same problem. Could it be something to do with the installation? Any insights would be greatly appreciated!

thanks,
Neelima Karanam.

HI,
I would love to help but you have not stated the problem?

What is not working? all of it, some of it, just rag doll?

is it not recording, is it crashing? etc..

Thanks,
Brad

p.s. I just did a new vid. tutorial for the Area that should be up in a month or so that covers physics and rag doll use.

Hi,

As far as the rigid bodies go, no collisions are being detected. I animated a box to go through a wall, and made ‘em both rigid bodies and set the box as active and the wall as active on collision, and animated the box to go through the wall. The collision is not being detected. The box is going through the wall.

As for the ragdoll effect, I created a rigid body pipe that the character runs towards. So upon collision, the ragdoll properties can be seen. But the character would simply go through the rigid body. I followed the MB tutorial where the character should collapse upon activation. But that’s not happening either.

thanks,
Neelima Karanam.

did you add the physics solver to the scene, make it online and then either live or tell it to record to the take?

It sounds like everything else is correct but none of it works unless you have the main solver in the file and online.

Yes. I added the physics solver to the scene and made it online and then made it live as well.

Does the account you are using have Administrator privileges on the workstation?

If you have the object with physics applied selected in the Viewer, it will not solve.  Make sure it is not selected.

Try this..  I’ve created a simple scene.  All that is required (after unzipping) is for you to expand the Solvers folder in the Navigator, double click the Physics Solver ,and click on ‘live’ and the cube should start bouncing.

If this doesn’t work for you, I suspect it might be a permissions issue as suggested in an earlier post.

As you suspected, it was a permissions issue. It’s working now. Thanks for all your help.
