Hi. As a title said, float16 mesh does not work with built-in Projector component. https://issuetracker.unity3d.com/is...not-receive-any-projection-from-the-projector New 2019.3 mesh API (setting vertex attributes and data buffer) has huge potential for optimizing memory usage of meshes. It can be used for per-mesh fine tuning (different with Vertex Compression option in PlayerSettings, applied to all meshes). But many of Unity features doesn't work with float 16 mesh. Projector is one of not-working features.
