Crunch compression support

[Artein]

Hi, Artyom!
Hope you are doing well.

How it is possible to enable crunch compression for texture/atlas ?
Right now I see in Memory Profile that texture is RGBA32 and allocates 10MB (that is too much)

Ps. also MemoryProfiler with snapshot from Android divice shows the same 10MB. Is it okay, if I see such compression ratio in Editor?

Hey, Just use import settings on the generated atlas texture, same as with any other textures. The settings will be preserved when re-generating the atlas (make sure to use the latest version of the package, as this was added in one of the recent updates).

[Artein]

Yes, I have other crunched textures. The platform is Android

[elringus]

Double-checked and it seem to work fine on my end. In the example project, try building it as-is, the build size will be 250MB. Then set up max. compression on the 3 animation atlases and rebuild. The build size is now 60MB.

Thank you for helping me, Artyom!

For now, I am curious why BuildReport shows that, meanwhile having the texture in the build (it is regenerated on the fly?).
And as you can see, the size seems to be correct. How interesting...

Should I also mark the texture as addressable and add to some Naninovel-XXX group?

[elringus]

I don't have much experience with addressables, but iirc they should track the references automatically. So, if you already have the diced sprites "addressed", the system should include associated atlas automatically. Just make sure to not include (or otherwise implicitly reference) original sprite textures.

[Artein]

Yes, I don't reference the texture manually (only DicedSpriteAtlas).

It seems like the issue is that the texture is not packed within the build (even though I manually enable it in addressables). The first guess is that it is recreating somehow at the runtime. Will continue my investigation...
