Particles emitted via ParticleEmitters don't distribute properly in asset thumbnails

Assets with particle effects (namely models) don’t have their particles distributed properly which results in particles being clumped up at an attachment point, or they take up the volume of the part they’re in.

Example (clump on the left is parented to the attachment, clump on the right is parented to a part):

For reference this is what it looks like in studio:

Repro steps:
1- Make a model and add a ParticleEmitter such that the ParticleEmitter is emitting particles and is visible
2- Observe particles aren’t properly distributed/there are very few particles

Expected behavior

Particles emitted via ParticleEmitters should be properly distributed in asset thumbnails, and the amount of particles that show up is accurate.

We’ve filed a ticket to our internal database, and we’ll follow up when we have an update!

Thanks for the report!
