Please try to wait 4 days in-between bumps. As for your question, your picture does appear to be low quality, what are your engine scalability settings? If they are not set to Epic, try to change them to that. The view distance/foliage settings might be playing a role in the short-distance culling.
So i´ve checked if the start and end culling Options have any effects if i turn on wireframe mode and it does. In wireframe the grass is culling correctly. Here are two screenshots:
So the wireframe is rendered, but the actuall mesh not… seems like it must come from some LOD settings? hopefully this helps someone to understand what could cause this problem.
i already changed it to different values, but nothing affect really the texture render. I try now to reintall 4.8.3 and see if that helps and also check if the same bug appears in 4.9
The only thing i´ve also noticed was that if i disconnect the texture in the material editor, the meshes of the grass (Little squares without textures on it) will render correctly with the cull settings.
Otherwise i report it to epic, because this seems to be a hardware bug to me… (if they didnt saw already the thread by themselves)
