proper mesh geometry for animation?
Hi, i was wondering if you guys might have tips for me on this particular topic. I have made my model and rigged it, but the shoulders and crotch area tend to give me trouble when they are animated (shoulder gives problems with arm from straight down to straight up and crotch gives me trouble when the legs are spread… -
Re: proper mesh geometry for animation?
Thanks for the info, guys. MoP, I'll look into the skeleton alignment, good point. And Rick, thanks for the drawing, i usually go about extruding the arms straight out of the torso, then use the cut tool to define the shoulder shape. Though, i am only making the rigs at our school project, someone else is modelling, but… -

If you can bake the animation then using the skin modifier instead of physique might be a better option for animating for effect. You can use the morph angle deformer to tweak out your sequences then bake the results. -

The only way it won't clip into the legs is to hand key every animation, or use a cloth sim. Or use a cloth sim and then key those verts. -

Okay, at that polycount vertex animation should still be reasonable. At the polycounts fighting games use nowadays (anywhere from 10k upwards) it would kill the framerate and RAM. -
Re: proper mesh geometry for animation?
Thanks for the tips. I started out fairly low detailed because i wanted to practice rigging and modeling good geometry for animation, so that i can apply the things i learned from it to my future models. I will go look through other people's wires and try to change the edgeflow as i see fit. Here's the particular stance… -

We're working with Virtools, so baking cloth sim to keys might be possible. -
Re: proper mesh geometry for animation?
Ok, I've knocked this us, I hope it can help a little. The body can be considered to be built in sections, that all flow into each other. No parts don't flow! You built the arm by extruding out from the body, but you want to extrude a shoulder out, then an arm DOWN from that. -

Evaluations aside, your deformation is not that bad. Before you make further alterations, try a test UV map to see the "real" result. Don't readily evaluate the deformation behavior by its underlying appearance, as the general user will not know the difference. If it looks good in skin, leave it be. Otherwise, if it still… -
Re: proper mesh geometry for animation?
Yeah, you need at least another row of edges around the leg at the top. Also it looks like your pivot point for the upper leg bone is too low... see if you can find some anatomical drawings or images where the skeleton is shown overlaid onto the human body shape, and try to match your rig's bones to the places that real…
