X-Particles (emit from specific area on Object)


#1

Hello,
Spending these days on learning X-Particles
I want to learn to add trails from like a tip of a shoe, and then fill out the entire shoe.
I’ve attached a screenshot, which I’ve tried to recreate on my own in XP (with my own OBJ model of a shoe). But can’t get it to emit from the tip of the shoe.

Anyone knows a tutorials, or can help me out with understand the build for this?

You could just model a part of the tip, make it invisible to render, and use that mesh as the emitter. (xpEmitter > Object tab > Emitter Shape > Object). Or you can select the polygons you want to emit from, set a selection tag, and drag that into the Emitter Shape > Object > Selection slot.

The online documentation is pretty comprehensive.

I would use a texture to control the particle emission. Something like a gradient going left to right would work in your example. The online help has good instructions for using a texture to control emission; check that out and you should be good to go.
