Iphone 4 (Some Images Black Squares)

Since the latest Unity updates, I'm getting poor performance on iPhone 4 and now to make things worse I get black square for some images:

Setting:

Sprite (2D and UI)
No Mip Maps
Max Size 4096
Format Compressed
Compression Best

4096x4096 RGBA Compressed PVRTC 4 bit

Not sure whats changed as this worked before, tested on 4.6.3

Anyone else have same issue?

 

I'd suggest it's the texture size, iPhone 4 max is 2048x2048

Not an 'official' list but this lists most devices and max size: http://answers.unity3d.com/questions/563094/mobile-max-texture-size.html

 

Thanks for the response, but I have one build for all iPhone devices?
So how do I overcome this issue?, my graphics settings are Automatic mode.

 

I'm not sure if Unity has a specific way to handle this, but when targeting mobile I stick with 2048x2048 max just to be safe.

 

Cool will keep this in mind in the next update release I do.

 

You could have a 2048x2048 texture as default, which switches to 4096x4096 if a supported device is detected in Start.

 

Hey @moonjump are you saying Unity provides this feature or are you saying to manually switch textures if the device supports larger textures?

 

I'm saying manually. Check against iPhoneGeneration in the Awake function. Then change the texture in the Material.
