Having trouble getting the correct address to play a particle effect. Done a lot of trial and error and read a lot of threads and guides to no success.
Part of the confusion came because the manual for Particle FX does not mention it (specifically this spot here, which links to the dedicated particle fx but not gui fx)
Perhaps it would be helpful to include a link to the GUI FX documentation in that spot as well, since this page seems to cover Particle FX for both objects and gui instances.
