How do I do realistic grass on a static mesh is this possible?

I’d like to have grass on the floor of a room in a section of my map, but the floors a static mesh and not a landscape, so hows this done?

you can use all the landscape tools for painting foliage on static mesh’s too, there’s a check box in the tool settings. is that what you were after?

Thanks for your reply, I’d like it to look like real blades of grass, I know you can paint the material on but im wondering about the foliage meshes to make it look real

Could I just replicate the grass static mesh many times, but how many times would many be and what would the effect on performance be?

Does Anybody know?

This is what you want. You don’t need to have any landscape even, just tick that checkbox and you could paint over any static mesh

Ah ok Thanks

that’s exactly what I said lol
also, yes having many meshes that aren’t instanced is very bad for performance

Sorry, thanks for your input, I’m just having a breakdown of sorts atm!

How do you get around the many meshes problem?

when you use the foliage tools, it automatically transforms them into instanced static meshes, basically, ue4 treats them as one big mesh to reduce draw call count which helps reduce CPU usage.

here are some great guides on optimization:
