Robotic arm rig in 3ds max

barnesy

Hi Polycount, 

I'm having issues with trying to rig a robotic arm. I want to stop any sort of rotations on the X and Z axis but I seem to be having no luck. I've setup a simple HI solver and tried snapping the bones to dummies so that they match the picot point of the arm chunks. 

I've also tried playing around with locking some of the axis in the link info. 



Should I be disabling the axis in the curve editor instead? Or is it not possible to have the ease of movement that I'm looking for with the simple constraints? 

Thanks in advance!

Have you tried building the rig using Cat? You get FK/IK hybrid blend for free. The axis locks should just work as simply as ticking the axis you want to lock.
