Question Properly intersecting alpha-mapped quads? (like grass billboards)

I've seen tutorials talking about grass made out of intersecting quads but when I try it the intersection isn't handled properly - it seems to draw one quad completely then the other.

I've tried every option in the shader graph for depth write and depth test - but none give the desired results.

The best I've been able to do is add two more quads so there is no intersection: (where each quad is a separate object - taking up 1/4 or one side of it)

When I tried combining the four quads into a single mesh it behaves like two intersecting quads even though the vertices aren't joined - I turned "weld vertices" in FBX import off - and even tried leaving a gap between the quads....


Is there some way of making two quads intersect properly?

 

you need to take alpha clipping not transparency
Transparency will be extremely expensive and its sorting is not really solved (?) in computer graphics
Also pro tip is to take only a triangle each

 

I enabled "Alpha Clipping" in the shader options and it seems to still have the same rendering problem. As far as transparency goes, in the built-in shader graph it only has the options of "Opaque" and "Transparent".

My grass/flowers are like Minecraft (i.e. not millions in view) and can be painted (not static) and are more about efficient use of textures rather than reducing the triangles... if I am using four different objects for the parts then I can't seem to paint them simultaneously with the same texture...

 

Thanks! I set it to "opaque" and "alpha clipping" and it works!

The alpha clipping boundary isn't smooth but that's ok.
