So this is my first app and I am stuck and for almost a week I can't find a solution. I've created a lot of animations for different characters and found out that my game' memory usage is about 200 mb. Before I didn't worry about this because, as many beginners I thought that after I'll compress my png textures this size will decrease also. But that didn't happen. So I started to search what I can do about it and found out that changing the texture format from default RGBA8888 to RGBA4444 can reduce memory usage almost by half.
I found an answer Sprite Kit Texture Atlas: Define Image Format (RGBA4444, RGB565, …) where it says that you can change the output format from the Build Settings > Output Texture Atlas Format. But that doesn't work for me, because my Atlases are created in the assets.xassets folder. "Build Settings > Output Texture Atlas Format" settings are there only when you create an atlas in the project folder and not in the assets.xassets folder.
So my next step was to change the textures format manually in the TexturePacker. And I did that, but the problem is when I've add these new textures back to assets.xassets folder, even their quality is low, but they still have the same memory usage as textures with RGBA8888 format.
I've read a lot of resources but didn't find any information about how to change the Output Texture Atlas Format if Sprite Atlas is in the assets.xassets folder.
So at this point I don't know what to do, and my question is - How can I change the texture format to RGBA4444 for my Sprite Atlases in assets.xassets folder? Thanks in advance.
