Hello

I want to buy some human faces and to add facial expression : happy - sad - shout etc
my questions are

- Morphing or skeleton animations ?

- Should you normally tweak the mesh only or the texture as well ?

- Do you need basic meshes and textures being specifically designed for expression ?

Thanks in advance

i'm not volunteering, just answering your questions:

- depends on the animation of your character, you cannot combine bones and vertex animation techniques (afaik, maybe that has changed already)
- mesh is always the best solution. but you may think about setting a raised eyebrow via skin

if you want to buy anything, post your request in "jobs offered".

Morphing is the way to go for facial animations. There is no need for tweaking textures, as it would increase un-necessary complexity. And same holds for expressions, Unless it is necessary for the kind of project you are doing.

Simple morphs go a great way in conveying your message. But it would depend on your projet.LOL.

Edit : And adding to broozar's reply, you can combine the skeleton and mesh deforfations at run time. Its only that skeleton and mesh morphing is not supported in same frames in mdl but they can exist in seperate frames. Good way to have in mdl. LOL.

All things that deform only particular areas on your mesh and are needed on demand should be done via bone morphing (vertex morphing is not supported by A/).

So you can compose during runtime (as it already have been said) your running primary animation with unlimited additional local bone morphs.

If you need a software solution for this (regarding the programming aspects), call me.
