Question by Exalia · Nov 21, 2013 at 01:11 PM · texturestexture compressioncompressed

Does unity really support ASTC?

I'm running a game with ASTC texture compression, however I'm using ADB to check what's actually happening at runtime.

I get several messages telling me

"WARNING: no native support for texture format 5, converting to 4!"

I'm getting this message while running my application on a note3 (which does support ASTC)

There is no decompression, just a conversion.

On a device that does not support ASTC (Nexus 10) ADB tells me the device does not support, and decompresses it then and there, resulting in huge loading times.

On a note3 the loading time is fine but I'm still getting this warning.

WARNING: no native support for texture format 5, converting to 4

I believe this is actually ASTC at work, right there.

No problem :)

I believe before this implementation a Texture format 5 game would have simply crashed if the device didn't support the textures.
