With Nanite and Opacity Mask the flowers cull, If I disable opacity mask and keep nanite on it no longer culls, If I disable Nanite and keep opacity mask on it does not cull, What setting in nanite or the material do I need to change to get this to stop. I have tried quite a few things already. Preserve Area is on, Changing the Mip maps on the texture does nothing. Messed with Nanite options on the emsh etc

Issue was do to the opacity planes not being connected together plus low Subdivision if you have planes that cross each other. Before placing them on trees etc. Merge the vertices where the two planes cross creating a single merged mesh and subdivide that mesh.
