Hi,

I'm having different issues on using alembic files from Maya to Houdini.

First I made some fractures on an alembic from maya with animation.
For some reason when my pieces are done, when the animation of the object starts, my pieces are doing strange things (rotating on themselves…)
I tried to say with Wrangle Node and sopsolver to keep the animation of the alembic until the explosion frame, with @animated = 1; but the problem still happens.

So in order to escape this problem, i used an alembic without animation to frac my pieces and saying “i will translate my animation with another alembic later”.
But i can't figure out how to use data from a moving alembic file on this non moving alembic file.

I tried to use FBX with rig inside, copying Nulls values, I tried alembic xform and chopnet but I don't really know how to use them and i can't find anything anywhere.

So here i'm trying to animate my object in Houdini itself onto my moving alembic, frame by frame during 253 frames…

It's long and painful but now my Houdini is crashing sometimes when i modify values of my animated NUll that drives my frac object.
(Is there any link with CCLeaner clearing cache while i was using houdini ?)

I'm trying to be clear but don't hesitate asking further infos !
And sorry for bad english.

Thanks

Thomas
