I cannot find ASTC settings for ios in 4.9,I think the engine packages ios with PVRTC format for default not the ASTC format.How can I enable ASTCformat?
Here’s what has been mentioned in 4.7 release:
New: Added ASTC texture support for Metal on iOS (Android coming soon). Enable via an iOS project setting (you can cook one or both PVRTC and ASTC).
Thanks!
