Erosion mapping

What? That is the built-in grass patch? Just shoot me. I am ready to pack my toys and leave the sandbox right now....

Ok, it's awesome. I'll take it as another inspiration.

Initially when Ulco mentioned he used the grass patch way back I started looking for it and he is the best at distributing it in a 'real' feeling way..felt the same on both counts and now consider it a major tool....

I reduced it to 1m with 1000 blades of 3.5 the default length, and added grass colors (of the terrain, in which I had some tiny dots, perhaps even fake stones, as mask for the yellow flowers) through a transform shader. And set it to rotate with terrain 100% with no restriction, but you need an extra compute normal (patch default 1m) at the end of the line for the pop to sit on. And (as I found) increase color to above 1 in the default shader, and set translucency, etc.

Thanks for the walk thru Ulco...good trick with the FS flowers...will remember that...will be handy with the free version and only 3 pops in TG3.

Looks great.  I'll have to give this a try on some of my rock stuff.
