Lamp Lower Arms WIP

Something tells me this is going to be a challenge to rig

Against my reference:

[DustinWoods]

Have you rigged this yet? Was it challenging?

It’s kinda working… just the lower arm so far. I was quite clueless so it took a while. I tried to share my experience as best I could.
Weird, I started writing this topic about 20min ago

Lamp Lower Arm rig... not quite working

Going with my theme of underestimating things… this took a while to get anywhere with and it is not quite there yet. I just wanna mention, I found parenting things to the armature easiest in pose mode… i.e. you select all the objects and then the armature last, go into pose-mode, select the bone you wanna parent to, ctrl-p. This was my bone setup for the lower arm at one x-rotation limit: [image] Extended to other x-rotation limit (for now): [image] Bone hierarchy: [image] LArm1 and MHi…

It looks so real looking have to look at it twice. I have no clue about spring stretch is there a modifier for that.

Thanks, but I think you may be confusing the reference image with the model… In this post I just managed to model the base…

I explain my reference image setup here:

Lamp base using curves

My base so far: [image] Method

(You have to expand the “method” section)

I did finally manage to figure out the springs and I posted about that here:

IK Limits (With springs)

Yes, I’m still on this rig… Took me a while to track this down after trying other bone-constraints like the stretch-to constraint which didn’t quite work for me… Instead I got the required results from stretchy 1-chain IK constraints pointing to fixed bones. [image] Setting the bone IK Stretch setting to 1 with a well-parented 1-chain IK constraint will perform the follow-and-stretch you would expect from a spring… (Eevee test render:) (Spring-bone targets ar…
