ParticleSystem could really use a flag where only the gravity is ignored in the position mode. For example, if you want to have a burning sword, you’d want to spawn the particles along the length of the sword no matter how it is rotated or scaled, etc. Here, position modes of relative or grouped would be really useful. But you’d want the smoke particles that the sword spawns to still float upwards, not “upwards relative to how the sword is rotated”.
Or is this somehow possible already?
