Good Looking Grass With Low Batch Count

I was wondering how I could make some good looking grass that can be densely packed with good performance. I have looked through previous questions and forums and I have found that using a custom tree looks good but I gives poor performance. Please help and thank you.

Well depends on your grass style.

unity terrain billboard grass is achieving a good performance.

i like speedtree grass aswell. but for custom grass use a good lod system! thats what for me worked out quite good!

I don’t have much knowledge about terrain, but this playlist had me intrigued as I work a lot with mesh building myself.
