Hi RecourseDesign,
Thanks for your answer.
So, in a traditional non-nanite LOD Pipeline, x-trees, sprites or imposters would indeed be used.
However, for nanite, imposters would not be necessary. It would be possible to have a regular mesh, that approaches the shape and silhouette of the mesh very closely. That is thanks to nanite’s triangle per pixel paradigm.
It would make it possible, to disable masked materials completely. Without any difference in visuals. Or almost none. But the performance savings would be very high.
