Excuse me for being dumb but aren't particles meant to be billboards, meaning they look the same no matter what angle you view them from? If they aren't, why don't you just edit the particle system to make them billboards?

they're not just meant to be billboards, but they are :wink: and are implemented as such. The problem is that they are in no way individually accessible, as they are handled internally by the particle system node.

I would be nice if we had a new particle system wihch can handle billboards but also axialbillboard (for making rain for example) and standard nodes so the range of effects will be greater.
And what do you think about particle system that produces particules of different sizes because currently there just one size for all particles for an emitter.

Simple answer to that problem is to create two emmiters in exactly the same position but each producing two different sizes of particles.

Or you can have more control over the whole system.

I wrote my own particle engine.
Works rather nicely too.

I have total control over the particle systems without modifying the irrlicht dll.

All you do is attach whatever you want to the particles scene node.
Be it a model, billboard, axial billboard whatever.

And you control when and how particles are created, Size, velocity, texture, ect..

The above effect..

Some more effects. That are easy to accomplish.

You control the movement and what the particle is.. So hope this helps.
All the effects where made with my particle engine..

hello,

I propose a patch in the same spirit as the qwe one but perhaps a little faster to compute here is the link :

@Atlantis: Do you have an idea how much of a performance hit your new flexible system incurs?

From what I've saw not much for me..

Although I still have on-board video.. And notice little to no drop in framerate... My system cycles through arrays of particles.. Just the same way irrlichts does.

I'm still working on enhancing it further.
