I'm a Cinema 4D noob, so excise me if it's a really obvious solution that i'm not seeing.
I'm trying to create a tearing piece of cloth, I've created a plan, applied the cloth tag to it and made all the sides into fixed points. After that I switched on the tear checkbox and the cloth ripped in the middle exactly the way I wanted, a few plays later the cloth no longer rips but the checkbox is still ticked and the sides are no longer fixed.
Is there a reason Cinema 4D is ignoring my settings, or am I missing something?
Cannot really say for sure but you might have changed the mesh somehow .. might have subdivided the plane or added or removed some points ..
That can remove the fixed points as the points on the mesh have changed so the cloth tag no longer recognizes the points..
