  • adding grass to floating chunks of dirt (a plane object)

    Posted by Darren Fetzer on November 21, 2010 at 8:49 am

    ok, so i have the desired gravity parameters that i want. when an object (square in this case) drops, it shatters the plane (that was precut with the knife tool and then function>melt. i have the gravity set so when the plane is shattered that it floats upwards quickly.

    now all i need to do is have hair attached to each of the broken panels, so it seems like the surface of the earth just got torn apart. i’ve tried for the lat 8+ hours to ge this to work and have made very little (if any) progress.

    can anyone shine some light on the subject?

    Hair can follow a moving object or the surface of a deformed object but that not what’s happening here. If you select the Plane then watch the animation the sliced parts fly away but the original plane lines stay where they are, that’s what the hair is rooted to so the hair does not move. You’re going to have to bake the animation of the plane parts then apply hair to those (I think). Adam may know more but I was able to find some threads

    and these two (which are referenced in the above link and seem like they might be promising)

    I don’t know if this is the right direction but I don’t have time to test at the moment
