To make it render with reasonable There are many games that render tons of grass without the GPU breaking as much as a sweat (Genshin Impact, Breath of the Wild, etc. Decentralization. The shader will take an input mesh, and from each vertex on the mesh generate a blade of grass using a geometry shader. The InfiniGRASS system main purpose is to massively optimize in game vegetation, for maximizing performance and allow big grass density and view distance with top rendering quality. Using Raycast, position the grass on top of the terrain. 2D. If grass has properties (can be cut down, slows down cars, ) you might want them to be actual objects (but not necessarily), in which case googling “Unity procedural object placement” will yield tons of results. So Instead of letting it go to rot away, I just made it free. Forks. I’ve been researching various grass shader methods in unity off and on for days. You can also use the Grass Mode on this node, but then you have to set This is a bit of a rant, and I’m hoping someone will tell me I’m wrong. Placing randomly generated grass blades given an extent and a density. And lately I have been working on larger new shader features that are moving more and more outside of the scope of Nature GGG is a geometry shader I was working on for quite a while. Audio.
