I want to share another procedure of planting 3d grass (Stixgames DX11 grass shader). This time to get the grass in a more clumpy and clustered fashion. This could be useful for planting the grass on forest floors, gravel, dunes or similar ground.
Some basic CourseForge and Blender knowledge is recommended but it's quite easy and lets you plant large areas in short time.
First select the desired spline in Course debug mode or in CF spline mode by clicking on the spline's name (here Spline 91) so the mesh frame is visible.
Then export your spline as an *.obj with the free OBJ exporter and save it.
Next import your *.obj in Blender.
Then in Edit mode use the Subdivide tool and play mainly with the Fractal setting to get something like this.
(If you add more steps of subdivison your file size can quickly explode. So be careful.)
When you're done export your altered *.obj and reimport it as an asset in Unity.
Place it above your original spline.
Then lower its position so that only the mesh's peaks are visible anymore.
Then assign your 3D grass(es) to the material slots. Depending on your *.obj's size Unity may have splitted it in several meshes.
With this procedure i quickly achieved something like this. Nice chaotic grass clusters with various orientation over a large area.
Results may vary completely depending on your settings, textures and and and. I also just started experimenting with this approach. There for sure are some drawbacks too, like the visible fading of the grass in the distance or the raised file sizes. Depending on your 3D grass' density or falloff setting you can't set the fade too far as well as the frames will suffer. But that's the nature of the 3D grass. I hope this still maybe useful here or there for some folks.
Just give it a try and have fun tweaking.
