Can't set thinInstanceCount for clone

Heya, while investigating a separate issue on this thread I stumbled onto an issue where the thinInstanceCount for a clone can’t be set to any value except for zero. Here’s a simple PG to show the issue.

It looks like a simple way to fix it is to fall back on using the source mesh to compute the clone’s numMaxInstances value, like on this PR for example.

Sweet it’s merged (and maybe later when it’s live I can make a slightly more interesting demo using it). :slight_smile: :beers:

thanks!! :slight_smile:
