Eye WIP

An eye rig and dynamic wrinkles test run.

  1. Probably the best I have seen for lightwave....the wrinkles seemed a little strong but as a proof of concept it is amazing....
    Care to share the rigging workflow?

  2. Thanks - I wanted to make the wrinkles somewhat obvious for the test, and subsurface scattering will dissolve them a bit anyway.

    There's a little bit about the rigging in this thread, and more if you follow the links therein.

  3. on second look...it is not so much the strength...but the fact that there is no crows feet around the eye after...
    the wrinkles are on again off...they should slightly remain....
    but that is just being picky...

    you are pretty close to perfect...especially for a WIP

  4. They're there, but it's subtle - just enough for a proof of concept. I'll have a go at doing it properly once I get some other technicalities out of the way (or sooner if I get bored with technicalities).

    somebody has to pave the way...

    look forward to progress!!

  6. wow, very good. how do you create the wrinkles?

    1. Using Dpont Tension node. Stress in the geometry affects the amplitude of Bump and displacement maps.

  8. Wonderful work. With the dynamic wrinkle maps, how are you blending the normal maps? With transparency or what? I'm trying to create a directx material that does the blending most efficiently in shaderfx, but I'm finding it difficult.

    1. If you mean the area on the forehead where the wrinkles cross over each other, I'm using a weight map that masks out one set of wrinkles whenever the other becomes active. I'm only using bump and displacement maps, I'm not sure I could get it working with normal maps.

    2. Ok I see. Is that the technique used for the snapper demo? I'm trying t get maps to work like they do in Photoshop and it's driving me nuts.

    3. I'm not sure how they're doing it, it looks more robust than mine though. MIne still has problems with wrinkle groups activating erroneously.
