How do I prevent XP from emitting inside holes in geometry? The hole in the letter "O" for example. Have it emiting correctly everywhere else

If you make the text editable you can restrict x-particles to polygon selections.

If you don't want to make it editable you could use a kill modifier to take out the hole particles.

I can't use the kill mod, the shapes are quite a bit more complex than the simple box or sphere's they allow.

And unfortunately the polygon selection had the exact same effect as not having the selection at all.

Attaching the scene file if anyone wants to take a crack at it

Couple problems with your file. First, all of the polygons are selected in your poly selection tag. Second, you have the emitter set to emit from object volume and it needs to be set to polygon center or polygon area in order for the poly selection tag to be taken into account.

Ya the volume effect is what I'm going for in this one, so that has to stay I'm afraid

Are you trying to have the particles fly around inside the letters?

Yes, and it's working minus the two letters with holes in them. Was thinking of just breaking out each piece of their geometry and emitting from those seperately

Okay, figured out the problem. The points are not welded. If you select the object and run the optimize command it works fine.
