[ray20ray]

what is the popular grass and tree solution on current Android or Oculus Quest 2 ?
does Unity initegrate SpeedTree?
or just use Screen-Aligned Billboard or cross-tree ?

should developer write some shader or c# or the GPU instancing is already inside the URP or HDRP ?

thanks!

Is alpha test still “the evil” for mobile ?

Is alpha test still "the evil" for mobile ?

So several years ago when there was the first iphones and PowerVR gpu, alpha testing was to be avoided because it had a huge performance hit. Is this still the case today? If I wanted to target a broad audience of current low end devices(max 3 years old) and iphones from Iphone 5 and later, is it still a big performance hit? Or is it like PC now where alpha test is even better performing than alpha blend?

so it’s better to use simiple triangle/quad grass model instead of surface/sprite to get massive grassland?
