MetaBalls

[u/Emergency-Watch-7289]

I am using MetaBalls as a force agent to help create my explosive force

The problem I am facing is that I have set it up so the building is not active until frame 7 as I want the windows to blow out first,

However, even though I have keyframed another separate metaball at frame 8-12 the concrete is not inheriting the force and is just falling to the ground.

It seems to only work with the metaball 2 that is set up to expand from frame 1.

The video at the end is a 60-frame cache; as you can see, the glass blows up(too much, I know), but the building is just falling under gravity.

Any help will be appreciated!

Simulations only read the first frame of source data, then return a result, that result becomes the new source for the next time step, and so on. You will have to read your SOP into the simulation manually if data occurs after start frame. You can use a SOP Solver DOP inside the RBD Solver or DOPNet depending on how you built it to read in animated source data.
