I have a scene that contains around 20,000 planes, all using the same material.
From a performance point of view, my instinct tells me that as they all share the same material, merging these meshes into single mesh would be more performant (as it reduces draw calls). However, I’m assuming that the whole of the mesh would still be passed to the GPU for rendering, regardless of whether polygons were visible to the camera or not.
OR - would it be better to keep the planes as separate objects so the culling mechanism doesn’t pass the to the GPU if they’re not visible?
Thanks in advance!
