Asset Set Textures

Hi folks,

I am planning to provide some assets as a bundle of many items (like for example 100 objects of one type).

Do you think that it is better to provide one image texture per object or have one large image texture for all.
Or maybe something in between?

If the client only uses a couple of the objects, a lot of memory will be wasted if one image is used.
For the other solution, many files would be needed, which is also not optimal.

What is the standard here?

Thanks a lot for your suggestions!
