View Full Version : nCloth Force Field nConstraint with a map?

Hi, maybe I just need more coffee, but I can't get a texture map to drive the force field constraint. I've plugged into the strength on the nComponent node, and on the dynamiceConstraint node. I tried the glue strength. I even tried the force.

I tried ramp textures and file textures.

I want to use an animated map to curl the edges of a pre-shattered surface, sort of like a time-lapse of a dry desert floor. The map will determine when the different areas start to curl.

thanks

Hi,

Thanks for the file. That's pretty cool. I got something going using two "attract to matching mesh" constraints - one set to effect "borders", that pulls the edges up.

People have told me that nCloth doesn't behave well with non-nCloth fields. That's why I was trying to use the nCloth "force field" nConstraint. Do you ever see problems using fields with nCloth?

PS - I gave Nicolas a big kiss, but I didn't tell him it was from you.

Noooooo, you must tell him its from me... are you working with him directly? :eek:

Who are these people!? Fields work fine, but ncloth doesnt act the same as it would using nucleus wind, which i believe takes into account the way normals are facing, etc.... doesnt matter really, as were always faking this fx stuff... just tweak and make it work ;)
