Blendshapes or bone based facial rig?

melviso · May 2012

hello guys..I really want to thank u gys for all the help I have gotten here.

I finally understand rigging to about 80 percent.I wanna ask about facial rigging.I am thinking of using blendshapes which I completely understand..I also understand how to use bones to rig a face.I am thinking facial rigging with bones gives better performance and u are not restricted as blendshape will involve a lot of vertices moving around and might be restrictive.
I am wondering if games now can use blendshapes and curves/clusters.i think UDK supports blendshapes now?What I am working on isn't for a game though but it would be nice to learn methods that improve animation performance especially during playback when animating or when the scene is heavy.

Thanks

Either method is acceptable. Morph targets use less CPU/GPU. But bones use less memory. I've used both methods in game development. Since your project isn't for a game use what you are comfortable with.

I typically use bones to make the morph targets. So personally I would just stick with that. You are also free to update geometry without worrying about recreating several morph targets.
