Custom Material detail sprites??

I’ve been fiddling around for ages trying to get something like this.

But to no avail, either the grass looks cropped badly or there are just ERROR messages instead of what is supposed to be there.

Anyone managed to do this? And mind explaining how?

Some how, while ago… i used some random texture for ground and it has black and gray grass on it, maybe u should use some blend textures etc. ?

What? I know how to use textures with them already on, but i am stuck on how to add custom ones.
