Documentation on Texture Arrays

Right now there is (as far as I can tell) zero documentation on texture arrays, despite it being possible to create them in engine with a simple click.

The only documentation is for the C++ class, with no information about, say, what they are, or how many textures you can put in one, or why they default to ‘NoMipmaps’, or anything at all. Does anyone have a link to an actual resource on this?

Cheers!

coming here just to say the same, no documentation of blueprint arrays. Does anyone knows anything? maybe they are focusing more in “verse” code for the future and they are planning to deprecate blueprints? just guessing. anyone who can add some light to this subject?
