Questions & Answers

Ok so i have a 512x63 texture.

In the inspector it says:
Only POT textures can be compressed into PVRTC format

ok that’s cool i understand that, so i set Non Power of 2 option to: ToNearest
The texture changes to 512x64 which is POT.

BUT NOW IT POPS UP MESSAGE IN DEBUG WINDOW:
Only square textures can be compressed to PVRTC format

lol what is the deal here? does it really have to be square?

Although the hardware on PVRTC enabled devices allows rectangular POT textures, AFAIU on iOS, the software insists on them being square. I’d guess this is the reason of the extra restriction.
