How to render a batch of mesh with only one textures

[HaoxiangYou]

I want to render a batch of mesh with same textures defined via TextureUV.
For each mesh the textures is exactly identical, so I wonder if it is possible to render multiple mesh at once with only one Textures to save memory, or at least one image stored in TextureUV map?

You can use expanded tensors to save memory - e.g. for the image. (And there's no need for a special API to support that.)
