Custom ASTC compression format

I would like to be able to specify an ASTC compression other than the default 6x6 for the Android textures.

The only solution I see at this point is to go into the editor code and change the command line that is used to compress the textures, but I’m trying to avoid making any engine modifications.

The engine.ini [/Script/UnrealEd.CookerSettings] can set the DefaultASTCQualityBySize value:


0=12x12
1=10x10
2=8x8
3=6x6
4=4x4

I saw some ASTC related commits on Github. Are we going to have high performance ASTC compression tools in 4.13 ? (at least to be on par with performance of ETC2 compressor)

4.13 uses Intel’s faster ASTC compressor.

Sweeeeeet!!! Hopefully it works and packages for mobile at least as fast as ETC2

Thanks

Yeah, looks like this setting is also available in the project settings under the cooking section:
