Is it possible to apply a deformer to only selected vertices in g3f?

IsaacNewton

I would like to move the teeth of a g3f model.

I can select the teeth in the Scene tab and use the transforms dials in the Posing tab, however that also moves the gums.

I can apply a deformer to g3f. Is it then possible to have the deformer work only on the selected verts (the teeth in this case)?

Yes - you can either use a weight map to control what the DForm affects, which is probably the easiest way to see what you are doing, or after you have spawned a morph from the DForm you can remove selected vertices from its effect. In you case I would think that using the weight map would be fairly simple:

1. create your DForm
2. move the Field out of the way (if it still affects the mesh at all that effect will be in the weight map when you create it, which is unlikely to be helpful)
3. switch to the Node Weight Map Brush tool
4. with the DForm selected, in Tool Settings in the lower section you should see Influence Weights listed as an Unused Map, make sure it is the selected map and click the Add Map button.
5. right-click in the viewport and select Geometry Selection>Select By>Surfaces and then the teeth surface - that will target the weight changes to the teeth. You may want to use the Geoemtry Editor tool to further refine the selection at this point.
6. once happy, with the Node Weight Map Brush active right-click and select Weight Editing>Fill Selected ands et the value to 100% - ypour teeth are now uniformly affected by the DForm
7. you may want to use the Node Weight Paint Brush and Geometry Selection tools to adjust the weighting, but that essentially is it.

Thanks Richard, I'll give that a whirl.

Ridiculous! This was so simple as explained by Richard!

Thanks to this, I finally got my weight maps working! Every tutorial was missing a step, but this one got them all!

Thank you both!

I've tried to use this method to create morph for hair, but it's only allow me to select the whole peice of surface hair.

so insted of trying to style it, it move the whole surface peice out of head.

I tried to alt + weight brush on it, but no effect was taking place.
