Force render Grass before level load

Hello everyone.

I used a material with a grass mesh output to paint grass and foliage on a landscape. However, when i load the level, it takes 3 to 4 seconds to render out the grass. I’m not having any trouble in the viewport and my hardware is definitely more than enough to deal with the small amount of grass i have in the scene. Is there a way to force the grass to load up completely before the level loads up?

thanks!

guys, anyone? still looking but haven’t found anything yet.

Have you made any headway on this? I am having the same problem.

Same problem here, any discoveries?
