nCloth under water

#1

hi! everyone. i need a little help with my project. i have to sim a cloth sheet under water. the cloth has to form certain shapes while under water.

i need a tip/trick. to make my cloth form a certain letter. without making it look stiff. or being pulled by constraints. i have to make it look as if the cloth moves by itself to form the shape and still maintain that under water flowing feel.

in my earlier attempts, i used input attract. i blendshaped my original mesh to form shapes. to pull the nCloth into forming shapes. it feels stiff. for the reason that it pulls the nCloth into its shape.

hope someone has an idea.

thanks in advance.

hmm this sounds quite tricky.
My suggestion would be to use input attract, but you say you have already tried this.

Ive never used blendshapes with cloth before so not sure how this would work, just some ideas:

You could try an in-between blendshape(s) that is somewhere between your cloth and your letter, which may help with the transition. If your stick some turbulence on a nCloth of your letter you may be able to get a nice gradual inbetween step.

Perhaps you could stick a deformer on the input mesh or simulate some turbulent cloth and geoCache it, using this is the input mesh may help get rid of the stiffness.

Again not sure how any of this would work in practice just maybe things to look in to.

thanks for the reply.

i ended up still using input attract. with small values. and using a texture ramp map for more control. and using deformers on my input mesh. i also used blendshapes on my input mesh to form the shapes i needed. the trick was to slow down the animation. more frames. for the cloth to have more time to follow the input mesh.
