FFD For Rigging

Augusto

Hello, I´ve an issue with FFD (WSM) when I want to filter the defformation the FFD does with vertex paint and volume select. I make 2 vertex map and 2 volume with different map channel so I can separate the influence of each one, but the FFD doesn´t interpret the different map channel so both FFD deformate both sides of the geometry. I know if I do half and half for each FFD it will work (because FFD works with the volume inside) but the idea is to separate this influence by the paint of the vertex paint. Hope do I have explained me correctly! Someone do know how I fix this issue? Thank you very much!

I would suggest using textures instead of vertex colors. Volume Select can use maps to control selections.

Also, the more complex you make your modifier stack, the more unstable it will be. Always collapse as much as possible.

Here's an example, in Max 2018 format. I added some keyframes, press the play button!

Eric, thank you very much for your quick answering! I appreciate so much your advices and suggestions but I need to do the same like that but with FFD(WSM) becuse afterward I want to put some controls in the FFD control points, unless you have some technique to make it with FFD modifier?

Again thank you very much!

If you find the modifier in Track View, it should have the control points exposed. I don't have Max here to check right now.

Prebiously I did check in the curve editor and didn´t I don´t figure out where can I control the ffd by external controls.

Even I dont see this points, it only show me the following items; Latice, Offset and Master. Anyone of thes dosn´t let me get to the point of control, even I did try to find some clue inside script control in Lattice where I found a Matrix3 line which I used to link with a external contrl but without sucsses.

Please, do you have some technique or correct way to make it?

Thank you very much!

Do you require FFD? Skin modifier with bones can give very good animation control. Also you can add the Morpher modifier for more precise shape editing.

Yes I know and I use it but sometimes modifiers are fastest and have nice deformations. I try to use the best of each tool.
