Sprite Atlas - preview not working

Hi.

Using Sprite Atlas for first time. 2018.2.0f2 personal edition (just while im learning how to use software).

I’ve created a sprite atlas, dragged in some sprites, then hit “Pack Preview” and nothing happens?

Ive got it all turned on in my editor settings/etc.

Why would this go wrong?

I get no warnings or errors?

Hi! I realize it’s kind of late, I tried atlasing today and nothing happened, when I read a little about it I noticed that it only takes sprites and textures. Make sure your images are tagged as sprites or textures and try again, it worked for me. Good luck all!
