Hi, on one of my projects after some time the sprite picker stopped showing sprite thumbnails. When you select a sprite in the scene, tap on the sprite thumbnail, this popup opens, allowing you to select another sprite for this game object. Atm this popup shows empty rects with checkers-style bg.
The reason might be that I am using a huge sprite collection with 400+ sprites which is also multi-atlas and stores all stuff in 21 textures, 1024x1024. However, even if I select sprites from different sprite collections, but in the same project, the thumbnails still don't show.
This problem slows down my work now significantly, since it was so much easier to find sprites by looking at the pictures, not just reading names..
I am using the 2.0 version, just re-imported 2dToolkit and the problem is still there.
