Sorry if this is a noob question, but I just can’t figure it out.

Hey I must be dumb cause I’m not really seeing the problem but…if it’s on the edge of blade of grass AA could help. If it’s a line outside of blade of grass (I think that’s in picture 1?), then this could be an issue with the mask in material and/or tiling. Try checking that.

Hope it helps at least a little bit, otherwise try posting image with the problem highlighted.

Never mind, I just figured it out.  
For anyone who has the same problem go to the details of your materials (on the left by default) and find the opacity mask clip value. Change the values until you find something that works. For me 0.2 worked.
