Hello everyone,

I am working on a short movie where I would like to use an APEX rig for the spider (main character).

I created manually one leg, and now I am looking for a way to make it 'procedural' or to work with tags to create 7 more




the main reason that I don't use MultyIK is that I would like to control the angle of the last section of the leg and to be always on one plane

if anyone can help me I will buy him/her a beer

scene file is attached

Check the spider-example in the Content-Library. It's complex but pure gold on so many levels. There you can see how to fully create a procedural spider-geo + joint-definitions by checking the .hda on the top. You could of course also use a Rig-VOP/VEX/Apex-Script that either creates all legs or which takes your first leg as prototype and creates the others.
I personally would create a Rig-VOP first until it works and then put it into Apex-code.

I did check Spider from Content-Library, but it just have IK solver for complete leg, as i mention before i need to have more control over tip of the leg, that's why i stared this post

Hi, unfortunately this version of the multiik doesnt support {segments} in the name of the parent. That would make things a lot simpler.

What I have done to work around that for this example is to write a little script that will parent the ik target to a tip control.
hope this helps

thanks, that is what I need from that leg

I'm probably overcomplicated it with the idea to have lookat at tip to align it always to body and then i stuck to option to work with tags for all legs

was this possible with the editgraph technique from Max Rose?

Im just using the snippet to write the component script. You can use the graph (editgraph) to do the same thing if you are more
comfortable doing it like that
