Maybe patches or something I can combine to cover areas in a scene. I bought a rug that uses fibremesh layers. I imagine you could do very short grass in a similar way. Flinks doesn't appear to be a "system". It's some meshes and some shaders. Or I'm not understanding how to use it. Basically I'd like to put some grass into my villa scene but not the usual "flat" grass textures that look awful, and also not meadow grass that's tall and uneven.
I imagine you could do it in unreal engine with some kind of parralax occlusion mapping - I don't think iRay supports that in Daz though. Kind of surprised at the lack of anything in the store to do it though.
Grass Shader for Daz Studio looks like it might be worth a try. Maybe I'll have to adjust shader to get nice stripe look....
I think that uses a custom 3Delight procedural shader. Don't expect it to work in Iray.
Wasted another fiver then. And yes, it doesn't work in iRay. It doesn't appear to work in 3DL either but whatever. Time to admit defeat.

Alright, I'll try that.
Looks vaguely plausible and could be constructed into a lawn (though lines would probably be too straight, i.e. too perfect). Only problem with it is performance. Just 3 strips here (consisting of 9 or so instances each) and it's really sluggish in viewport. Just this is generating 2 million vertices. No tessellation control. If I made a full lawn with it I think my house would burn down. In a game engine we'd probably use some rasterisation "trick" like parallax occlusion mapping, not available here in iRay of course.
This turns out to be a much more difficult problem than it appears, which I suppose explains everything.
What about this? https://www.daz3d.com/realistic-grass-evolution
Yea that's pretty much what it is at the moment: two patches of grass (one for each type), and all the rest are instances. I may try something with fur... hold this space.
Iray instances may be slow in the viewport, but they will render pretty fast in the GPU, as long as you set instancing optimization to Memory. Iray preview will treat the instances like individual full memory hog objects, even when you set instancing optimization to Memory.
