for each sdf

[Macha]

I have a fractured object sim, the result of which I saved out as a bgeo series.

Now I want to use these objects in another smoke sim.

But calculating one big massive sdf for this geometry (consisting of many small pieces) is not a good idea.

Can I loop through each object and create a small concise sdf for each object somehow. I guess there is some automatic way of doing this because it happens when we create fractured objects.

Or is there a different method?

Edit: Maybe just use the fractured object node...silly me...

To answer your question though, yes it's definitely possible to do a foreach and create sdf's inside that.

Yep, definitely work.

Also I recommend NOT using group names at all for the foreach iteration, instead use a Primitive group attribute, you can create one using the connectivity sop if you don't have one already, it'll be MUCH faster than using foreach per group name.

Hey, nice tip there Ratman. I did actually notice that groups slow down some things enormously (I often delete them when I can) but never made the mental connection to foreach.
