How to make the grass texture seamless with the ground?

Hey, so I’ve been experimenting with foliage and tried to create a more optimized style which is only 2 faces in a cross sort of formation and a texture, I’ve seen it work like the one on the right, yet what I got was the one in the left, I know the colors are off and that’s a factor but how do I manage to make the grass look less 3d and also there’s a weird little line over the faces that i’m not sure how to get rid of.
Thanks for reading.

Use Runtime virtual textures

You will very different results based on the type of mode you chose. Opacity will either be off or on, meanwhile translucency can have a gradient fade making the grass blades look smooth.
