Two Questions About Particles

I have two questions about particles, and I don’t see the need to make two posts.

First, how can I make particles show through parts, and second, how can I make particles not disappear when you get to far away

You can use ZOffset (ParticleEmitter.ZOffset) to determine if particles render top/bottom.

Not really sure if there are any ways to get around that for the second question.
