The ParticleEmitters are a great feature for most of the things regarding particles.
However at some points, we may need to make use of Billboard-, Screen- or SurfaceGuis.
But unfortunately those guis don’t have things like LightEmission, or other really handy properties like ParticleEmitters do.
It’d be really nice if guis had similar or the same properties as ParticleEmitters, so that we can improvise a lot better when ParticleEmitters can’t do the job.
Usage examples:
Fire made of spritesheets in a BillboardGui;
An orb of fire in a BillboardGui that you launch; (This could eventually be combined with ParticleEmitters ;))
And lots more!
