Is there any way to force FRED to use only certain sized asteroids in its box fields?  I'm trying to create what is supposed to be planetary rings, but full-sized asteroids seem too big for something like that.  I'd like to specify only smaller rocks.  Is there a relatively simple way to do this, or should I open a feature request?

Short of creating a new asteroids.tbl that would also affect your other missions?

Using "ship-create", "ship-vanish" and "ship-rot-maneuver" you can theoretically franken-emmulate what the asteroids editor does...

Sounds like I'm on to a feature request then.

Why not simply resize the POFs used for the asteroids?

This, of course, assumes that you are okay with applying the size change for every mission in the mod.

A global change of asteroid sizes for all missions in the campaign would not be the intention, no.  I've opened a feature request thread in the SCP forums.  It also brings up a few more upgrade suggestions.

I wish we could make bigger asteroid fields. I want to have a few missions set entirely in an enormous debris field from a planet and its moons, and that'll be difficult since you seem to only be able to have one asteroid field per mission...I'll probably have to make a skybox that has asteroids on it to add to the effect.

Multiple Fields and Field geometry are a different feature request (and one that has been around since I joined HLP).

However might I redirect your attention to this release from Shivan Hunter? It might serve your purpose
