However if you drag a static mesh version, it cast shadows again
This is my engine setting
This is the landscape grass setting.
The grass is a market place resource in 5.4, I migrate that to 5.5 project
perhaps you are using raytracing… which i do not beleive works on landscape material grass that autopopulates. If you are using ray traced shadows swithc to virtual shadow maps or use contact shadows.
Use virtual shadow maps, works for me, pixel-perfect crisp shadows at whatever distance; performant in 554.
