For this part I’ll go into some detail about the setup on the arms and claws as well as touch on a few other things as I prime this character for his first round of animation testing. More after the jump!
I mentioned in an earlier post that I thought the head would require the most complicated rig to work. Today’s post is to show that 1) I was sorely mistaken, and 2) the leg rig is quite interesting and borrowed a setup often used for the hind legs of cat and dog rigs. More after the jump!
I’ve now made further progress in rigging the legs. For the limbs, I’m implementing an IK/FK setup. My approach for setting up the switch is a twist on the standard 3-bone setup where the original joint chain is duplicated and influenced by two separate chains.
Positing a minor update. With the rig completed for the spine and tail, today I mostly focused on creating a proxy mesh for the newly rigged areas. A handy tool I like to use when building proxy models is zooSurgeon. This neat script takes a skinned mesh, breaks it down to solid segments, and constrains the segments to influencing joints. I incorporate this script in my workflow by first skinning the reduced mesh using solid weights (one joint per vertex), and then running the script to get my true proxy. For me, this is efficient because I can preview the behavior of the proxy prior to breaking down the model.
Here we are, part three, and progress is looking good. For this post, I’ll describe some of the processes I’m using to set up the spine and tail’s behavior. Read on!
3ds Max is relatively new to me and I’m very much used to the way maya does a lot of things. To get an animated texture to work in Maya, you simply make a material and assign an image sequence or movie to it. Max also does this but there is a snag.
When importing an animated texture in either package, the default is to sync the texture’s animation with the scene’s time slider. For the particular project I’m working on, I need to to have the frames of the texture controlled by a control in the rig so the animator can play with it (the texture in this case being the pupil of a cartoon eye). Max’s bitmap has no way of reconnecting the active frame of the texture. There was once a plug-in to achieve this feature, but it’s not compatible with 2008. Running out of time, I came up with a ghetto solution that still does the trick.
