RGBA Compressed ASTC6X6 UNorm not working on ipad mini 3?

Unity Engine

Helllo,

I am seeing the following outputs when debugging a memory crash.

“WARNING: RGBA Compressed ASTC6X6 UNorm format is not supported, decompressing texture”

I found that this is the default format for Unity and iOS devices.

I also found that it wont work on older iOS devices, but my understanding is that the ipad mini 3 should be fine.

Any ideas what might be happening here?

Thank you
Les

No, that’s correct. The Mini 3 uses the A7 SoC with a first generation Rogue PowerVR GPU. The A8 (used in the Mini 4 and iPhone 6) was the first Apple SoC to support ASTC.

(The iPad Mini 3 is the same internal hardware as the Mini 2.)

Ok, thanks for that info. That explains things then. Cheers
