Hello,

Is there a way to activate pieces like the example provide with the help ( active attribute override) but with RBD solver not Bullet. i can't get it to work with RBD

thanks or your help

Hey vbk,

Had some time to come up with this scene. I use this method quite often for destruction involving clustering activated at different frames, hope this is similar to what you are looking for :-)

Strange … I didn't recieve mail to warn about your post Yash Polke .
I can't check your file right now. But I attempted something myself.
I use points and use an expression to read their attributes to DOP using $OBJID to run through the points.
it allows me to make a group which I use in an Active node.
Is it the same thing in your hip ?

Hey Vbk,

Yeah must be a bug or something I dont get notifications either.

Well its somewhat similar,
what I do is make clusters based on an attrib transfer so basically I have an activeFrame attrib on the points and I transfer them to the geo which creates clusters, hence each cluster has a frame num that the point possess.

So at sop level I set everything to static using i@active = 0 and in dops I create static packed geo and use a pop wrangle to import the active frame and basically say that if curr frame is greater than or equal to activeFrame then i@active = 1 else its 0 and at the same time source velocity that I set in sops all before the curr frame reaches the activeframe and shoots it out when the currFrame = activeFrame and I break constraints based on this activeframe too

So all in all I setup everything in SOPS and just import the stuff in DOPS rather than calculating everything at sim time which is the way you mentioned in the above post, its just more easier to control for me and know which piece or cluster will be active at what time and which cluster will shoot how far based in frame and velocity already setup in SOPS

This is what it looks like [vimeo.com]

Hope that helps! :-)

Far better than my little setup.
It will help a lot in the future.

thanks a lot for your help Skadoosh.
