fractured problem

[imoh3n]

hi everyone.

i have a problem with fractured RBD objects, i want to sop groups evaluated on each frame. i upload a scene that my object separated in 2 piece on frame 19, but in dop network, upper part gone.

i hope if anybody help me.

hi,

to keep things simple you could set your creation frame in the RBDfracturedobject

to 19 because by default it loads in geometry only once.

If you really would like to do this whole thing procedural then you would have to

set your creation frame to $FF. However as you will see now the solver creates

objects on every frame based on the incoming geometry, which will lead you to a

whole bunch of boxes.

There is a solution for this. You could load your geometry once at the time the

two groups part_0 and part_1 are created and then delete the geometry the next frame.

So you have to create an attribute which determines the specific frame. However Houdini

apperently finds it hard to memorize frames at SOP level, I haven't found a solution

to this yet, but I'm interested in this too!

One expression to start with would be to look if there are 2 part_ groups:

argc(primgrouplist("/obj/box_object1/partition1")) == 2

have also a look at this topic to get you started:

One thing I was wondering: I couldn't find a way to keep the boxes from sinking into each

other, even if i was to increase the geometry's subdivision, upper the ray intersect divisions and

set the surface representation from points to edges ?!

all the best,

Manuel

thanks asnowcappedromance.

i uploaded a simple example, but my problem is that i work on high detail model with some groups that change every frame.

i have to find a way to work fine on procedural models.
