View Full Version : image maps for facial animation questions
12-27-2008, 01:58 AM
I'm interested in making a character that uses image maps for eyes/mouth (think Pocoyo).
I'm wondering if anyone knows of any tutorials (paid or otherwise) that have a good simple (emphasis on simple!) example of setting up a facial animation rig for a character like this.
It seems that XSI has the tools to do this using Warp FCurve in an image clip. I guess what I'm looking for is how a smarter XSI user than I (most users!) might go about this to aid in a better workflow (maybe using synoptic views so an animator could choose from different mouth/eye shapes and key facial expressions?).
Thanks for your thoughts,

This is really easy to do with the "texture layer editor".
You can link the weight sliders with your own custom panel for better control.

You know, I had never really used the texture layer editor (as it just seemed to be another layer of abstraction to the render tree) but it is nice that when you add a layer, it automatically adds a diffuse and ambient property and sets them to 1. It's a bit fiddly to add all that in the render tree, so I can see using the layer editor quite a bit now since I do a lot of texturing with layers.
Using the weight hadn't really occured to me at all. I've set up a quick little parameter set and have some controls in the viewport using DisplayInfo. Pretty neat.
I guess the next step up from this would be to do a script-based parameter set.
What would be nice is if selecting one parameter would toggle on the image (set a key with a "1" value) while toggling OFF the other images in the set (setting a weight key at "0". I've never done any real scripting of any kind so this might be beyond me.
Thanks for your help Manny. Your dvd looks really good... I would have already gotten it if my snail mail wasn't so spotty and I wasn't travelling so much.
Any chance of offering a downloadable version? (I guess it's the server cost of hosting that much data for download that would make it difficult?)
