Why does my grass mesh appear in rows when i paint on my terrain?

I bought a grass pack on the unity store, and started mixing with it(colors, wind and such) and when i paint it on the terrain it appears but when i paint on the same spot again some of it dissapears in a PERFECT row, like if the terrain thinks it is some grass there but it is’nt, i can erase on that empty-row and paint there again and it would appear grass there again, but if i go left and right with the leftmouse button down it would start to dissapear in rows again. WHYY :c

I am having the same problem. Sure would like an answer.

@chippwalters This might be because you’re exceeding the 65k vertex limit. Try lowering the detail resolution per patch or amount of vertices in your grass models.
