How to properly Purge unused source blocks?

[kevo]

I'm new to skatter, but have been getting good results so far.
I have a skp file where I initially brought in a load of files/proxies to use as skatter objects.
My various 'skatters' are render only, and I only used a small-ish selection of the initial components I brought in to the file - but it's difficult/laborious to narrow down which ones I've used.

I thought I could just delete all the source components and then purge my sketchup file and skatter would 'remember' the blocks for the render output. But this isn't the case, if I purge the skattered blocks vanish.

Is there anything I can do in my existing file, beside going through one by one?

For future models, what would be a better workflow? Should I be adding all my potential components to the skatter library, or something?

Thanks!

I'm afraid there isn't a simple solution to purge only the components not used by Skatter.

The best is to keep a copy of the objects somewhere in the model (they can be hidden if needed), so that they won't get purged.

No problem. Just wasn't sure if I was missing something.

I haven't tried this yet, but I think if I duplicate my render only skatters, and create a small sample of the blocks (with render only turned off) somewhere off camera, then do the purge. It should get me somewhere close.

Can you edit generated skatters that were created with render turned off, or are they delete and recreate?

Excellent idea!

Yes you can, just right-click on the group, then "Edit Skatter group"
