Grass Particle System How do I do this without a base? I have learnt how to create random particles using objects (like grass), however these extrude from a base mesh/platform, How can I create random multiple objects (like grass) without extruding them from a particular base?

When I import this into UE4 it has a base and sits awkwardly on the landscape.
If you select the base mesh and go to the object modifiers tab, the particle system is there. If you then hit convert then it should duplicate the grass into a separate model, where then you could delete the base.
