ahahahaha ))))

heh, wake all night, got demons to fight - tried to add some details, but these attempts turned out to far worse results then without them ))) must try harder ahaha.but i messed with topology - any luck with lagoa`s guts ?

You mean that the knife should cut it ANYWAY - independent from the speed. touch=cut ? like this ?
hmmm...yeah, 0 gives some cut problems.
But i`ve got nice results with 0.1 and 0.01 ))) ahahaha

ZUG ZUG !!!!!!! piece of cake - inside the Lagoa Setup Throw Breakable Structure -> Lagoa Multiphisics -> Collisions tab -> Offset Collision
set it to 0

Concerning the bad polygons i think there was a compound around to delete by polygon size, maybe it would work inj this, i will try to find it. Of course better would one that would not make possible to have U or V biogger than a certain size emmm...actually i DO deleting them by area size and by ed...

okay Hirazi )))

Bullit, can you send a scene to me, i will look. and can you send an example, what look of the rip you want EXACTLY, cause the bad polygons are appearing because of non-polished algorythm ))) i actually expected that someone will suggest an idea for it ))) ahahahaha

its no problem, brother, i can return ))))

oooh, did you tried my scene or yours? Maybe should tweak the Elastic Breaking Point at Lagoa Setup? in mine all working, i checked again. Btw is there a way to give more detail/definition to the cloth? i thought about it, yeah, but totally forgot, since no one is interested - more detail, yeah, it ...

Further development of the "cloth tearing in Softimage ICE" ideas. Now making mesh from strands.

uploaded at you tube at last )))

aaar, you are editing your posts ))) all of the questions will be answered when the vimeo servers will wake up, its kind tricky to explain from the middle on fingers )))

I am seeing that the sphere cuts the cloth if moved but the cloth hitting the object doesn't cut it.

absolutely correct - the blade object must be swinging with some force and velocity

wow, really, transform constraint works, but it little bit tricky to find the exact value for the Elastic Breaking Point - it is tearing off from constraint with the same nice way, like from blade ))) i think it should be solved with per point Elasticity Breaking Point attribute - paint it with weig...

hmmm...something strange in a neighbourhood - commonly its converting for 30 mins, its 6 hours now waiting in line.my bad, i should`n post it too early, forgive me, friends.i think i`ll upload it at youtube...arrrr - same crap at the tube - it swallowed it, but not showing aaand, Bullit, i understan...

5 sec, its converting on vimeo, i have a habit post everywhere and go to sleep ))) ahahaha
