RBD Fractured object and Blend solver

Hello,

I want to blend animation for fractured object made in dops with some “hand-made” animation.

Hand-made is just a popnet with number of particles equal to number of pieces.

Blending works, but all pieces follows one particle instead of following individual particle for each fractured piece.

What's wrong with this setup?

Thanks.

Saw this file a bit earlier
It's not exactly what I was looking for because I'm trying to deal with blend solver and this setup use slightly different way.

I was trying to understand if blend solver will work with fractured object or not.

I see… I don't exactly know why the blend solver then, could you expand on the specific need of a blend solver setup?
I've achieved similar results using the keyframe active DOP and procedurally activating it based on DOPs data (impact, or any ohter data, like particle age, for example). So maybe if I understood the problem I could help more… or not…

Cheers

The goal is to achieve smooth blending between rbd sim and hand-made anim.

This example is what I'm trying to do, except jump at frame 70 when switching from simulation to points animation.

If make this transition smooth over time - this will be exactly what I'm looking for.

Thanks for your help.

I am wondering since the 2 sims do not interact with eachother that you might just want to do the blend as a post process in sops? Here is an exampel file:
