The documentation [for reducing .apk file size][1] suggest in my case of using ETC1 format for android:
“If your project does require Textures that use Alpha’s it is better to use two separate Textures, one for the Diffuse and one for the Alpha, instead of a single Texture with the Alpha embedded inside of it as this will ensure that the Textures will be compressed when your project is cooked and packaged.”
Then I can’t find the way to tell my Paper2D sprite to use two separated textures for diffuse and alpha, I’m using “TranslucentUnlitSpriteMaterial” for all my sprites, I don’t know where to set the separated alpha textured.
I already have the new textures separated as RGB and alpha in two new .PNGs.
EDIT:
I’m playing with material editor, but once I have my new material created (3) how to tell the Sprite to get the texture (2) as alpha channel while using (1) as diffuse. It get the diffuse, but ingnores de alpha … see image:
