Custom Particle System

Question

I'm creating a game for an iphone with a custom particle system. Is it possible? If yes, will it impact performance more than using unity's inbuilt particle system.

I'm also trying to make it using instantiated 2d sprites (tk2d). Is it going to lag on my iphone?

Thanks.

It's possible to make a custom version of anything. Whether it affects performance more depends on how efficient you make it. If by "instantiated 2d sprites" you mean each particle is a separate object, that's definitely not efficient.

Hmm... I see. But the particles are made up from the same $$anonymous$$esh Atlas.... will that be more efficient?

If not, what could you suggest for an efficient system?

The built-in particle system uses a single mesh.

So:

Instantiate.overhead > UnityParticle.overhead? correct?

It depends on how many particles are involved.

If for the same number of particles?
