Question Animating a trunk

Hi everyone.

I have built this little dude, and have made him with a trunk. I want the trunk to flop down and act like it was a proper trunk. He is ready for animation with all his joints. But i would rather not use joints for his trunk. I would like it to behave natrualy. Any idea how i could animate it without useing joints?
check the pic if your confused

Thanks Heaps

Nick

Turn the trunk into a softbody - making sure to keep and hide the original. Then set the original as the goal and paint weights. Should do the trick.

I think using bones would work quite well.

I'm not a soft-body expert, but I don't think you can attach a softbody to another object. I think you'd want to duplicate the entire body and make all of it rigid except for the trunk. I'm not sure how rigging might be affected by that, though.

I dont have Maya in front of me, so cannot try this, but can you not parent the softbody to the poly?

you need to paint some weights on the trunk. try 1's up at the top.. and like a .5 lower. try to twist the original so that the trunk is in a more natrual position. you might also need to use some springs to keep it from falling to the flore.

thanks pony. I have it working well, I ended up useing about ten joints along the trunk. Then used a IK spline handle and attached a cluster to the vertex. I parented the cluster to a nurb sphere, then then attached another nurbs sphere to that, with a spring. It worked really well. This way i can control it with gravity and such. I had no luck with the soft body.. Thanks for all the replys
