Gras Dissapears in build

I've got a pretty grave problem

I have a scene with a lot of gras in it (maybe a little bit much, but I also tried with less gras instances).... I can see the gras in the editor, and also when I hit play.

But, as soon as I build the game, all gras disappears. The Terrain and other Objects are all normal, but the gras is gone (and once I got a crash and problems with the directional shadows after a minute or two).

Can someone point me in the direction as to what could be the problem? Is packing lots of gras into a scene leading to problems like that? (I place my gras procedurally, could that be the problem?)

Thanks for any help

You seem to be having a DETAIL problem.

Access your project’s

EDIT=> PROJECT SETTINGS=> QUALITY

and check what’s the quality the editor is set at, and then the quality at which your build runs. Then obviously run the executable at the same editor quality you use, to verify.

I don’t remember exactly where is that you set grass max distance render as a parameter, but I’m sure it’s detail-related (think it might be shadow-distance).
