Hi guys, 

We found a big problem in Unity with the tile setter.

it made me crazy last a few days. 

Let me talk about how to solve this problem easier.

first, Turn on "Always Enabled" on the sprite packer mode in the "Editor" section under the "Project Setting".

and Make the "Sprite Atlas".

and Drag and drop your texture on the "Objects for Packing" menu in the "Sprite Atlas".

Done!

We are focus the tutorial stage now :D

See you next week!
