Rigging a Scorpion Mech: Part Seven, Arms, Claws and Cleanup

screenshotFor 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!

Rigging a Scorpion Mech: Part Four, Progress on Proxy Model

Reduced model to about 12k polys. The original model is about 330k.

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.

Rigging a Scorpion Mech: Part One, Prepping the Model



I thought it be interesting to document my rigging process from start to finish using a fairly challenging model. I’m not going to push this series of tutorials as an “ideal” way to rig such a machination, but it will show one approach. I’m going to rig a scorpion model I came across in the forums of CGTalk (original post here). The artist, Nicholas Silveira, modeled and rigged the creature and was nice enough to share the bare model to give anyone else the oppurtunity to rig his creation.

Tips & Tricks: More memory for 3ds Max

here’s a bitmap error that comes up in 3ds Max when using exceedingly large texture files or fairly long image sequences in the scene. The error usually brings up this window:

I ran into this error recently with a rig that’s using more memory than 3ds Max’s current threshold. I did some poking around the Autodesk forums and came across a solution that seemed to work. Continue reading

Tips & Tricks: Animated Texture in 3ds Max

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.
