Square frame with particles - How?

Hiya!

I still have not figured out the logic of particles, but have an idea, which I hope someone can help me with.

Is it possible to make like a neon frame around a square picture object?

Why not using a neon-ish texture for the frame and add a small amount of glow?
Might be easier than with particles - plus: depending on the client's settings and amount of other particles on your land, some users might not be able to see the neon-frame...

Because I wanted to keep prims to an absolute minimum and I wanted the user to be able to ad his/her own pic to it....and having to think about making a neon frame.

Use taper on a box or cylinder to make a frame if you want to keep it to 1 prim, sounds a whole lot easier than particles and whatnot.

Particles are emitted from the geometric center of a prim, in a radius around that point, so it isn't possible to have particles emitted from the edges of a square. The suggestion the earlier posters made is a good one. Make the frame a glowing, flat, hollow box, then have the user put their on an inside rectangle. That's only two prims.

As others have said, it's not possible to emit particles in a square pattern,
but...
Good thinking! Shows that you have a creative approach to attacking building problems (and shows an interest in low-prim building), so don't stop thinking laterally just because this one is a no-can-do.

(hmmmm, something occurs to me though.... what if your particle texture had a square border, but was transparant inside, and was emitted at the same size as your picture object?)

(hmmmmm, although then the particle would always rotate to face the viewer, so that prolly wouldn't work )

It would be an interesting effect though, especially if you gave it a TINY upward velocity and used the "follow velocity" flag. Hmm.
