Hi guys,
I have a falling down ground fractured with voronoi. It have also a glue network. The pre-fracture with voronoi and an active glue network goes very well and i can export it with a correct alembic file.
Now i add a secondary fracture level with “make breakable tool” and the export doesn't work fine.
I add some keyframe to “enable Fracturing” value inside Fractureparms SOP to enable secondary fracturing only after frame 26.
The simulation goes very well but when i try to export it with ROP alembic output SOP, the result is very strange. Alembic export only the geometry without second fracturing enabled.
I suppose that i make something wrong with the Alembic export node in my network because when i add fractureparams node, Houdini add automatically a second dopeimport node in geometry sop that give me some errors.
Please give me some feedback!
Thanks for attention
Giovanni

Hi guys,
do you know why houdini during a simulation use only 10% of cpu? I have a 3630K six-core processor.
Thanks for attention

This is my simulation. The ground is an alembic file, the cube an rbd object.
Thanks a lot.

I'm sorry but i couldn't check your answers.. My internet connection didn't work.
So, i've riassembled a new scene with a ground fractured in houdini and imported inside it with an alembic as “houdini geometry”. Then i created a simple cube falling down on my ground.
At this time my cube falls down on the ground and collide wirh it but, when the fractured grouund pieces fall down, the cube doesn't fall.
I think that the cube consider the entire ground bounding box and doesn't consider any single pieces.
I'm sorry for my bad english.

Did you turn ON “Use Deforming Geometry” option in the static object !?
If No ,Select Static Object for sphere in the AutoDopNetwork and Turn On “Use Deforming Geometry”
Hi, thank you for answer. It still doesn't work. I have the same problem with a sphere created and animated inside Houdini. I don't know why.
what is the the correct pipeline to ensure that an animated object, imported in Houdini with alembic, collides with an RBD fractured obj created in Houdini?
Thanks a lot.

Hi guys. This is my first post on Houdini forum. I have some problems with dynamic object that i want to collide with a fractured object.
I create a fractured object in houidini with voronoi. Then i animate a sphere in Maya, i make cache for geometry and animation and export it as alembic simulation.
After i have imported my alembic in houdini (the animation works fine) I create a RBD fractured obj from my fractured obj and set my animated sphere as static obj.
When i start the simulation my sphere doesn't collide with my fractured obj but run througt it.
I also try with a rbd obj and a terrain obj but it doesn't work. My sphere with animation cached never collides with my RBD fracture OBJ.
