Procedural foliage in Open World without Landscape

With landscape, we can create landscape material to support procedural foliage, using the grass node. But if we don’t use landscape. like the Valley of Ancient and Matrix: Wake up demo. The grass node in landscape materal does not work on static mesh. How can we create procedural foliage in these situation?

You can write you own ( easier than it sounds ).

Or, you could use the pre 5.2 procedural foliage volume

Or, probably a better option, use the new PCG plugin

Thanks for your quick reply.

Can you tell me more details. In my project, I create an open world more than 500km*500km, I use the cesium-for-unreal plugin to dynamiclly load terrain. I want to create procedural foliage in the whole world, the editor tool is not a good choice. So I think I can create foliage at runtime by dynaimiclly loaded data and camera location, but it seems to be a complex job. I wonder if there is an easier way to do it.

Sorry, I know nothing about Cesium. Presumably, others have already got around this problem.

You might have more luck if you post again with Cesium specifically in the title or, try some Cesium support groups.
