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.

  • Separate the grass from the ground and don't export the ground – piegames Jan 03 '17 at 20:57

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.

  • Will UE4 generate each individual object offset and extrude them out accordingly since the mesh has bee removed? – Pyratae Jan 04 '17 at 19:34
  • The converted grass is just basic mesh data, no particle system if that's what you're asking – wyskoj Jan 04 '17 at 20:28
