How to import a .png and create a pvrtc4 with 5 mipmaps for example? I am using this code:

img.ImportTry(path,IMAGE_PVRTC4,IMAGE_2D,5);

but returns false. If I change 5 => 1 , it works but with only 1 mipmap.

No problems with other image types. SupportPVRTC(); is called in InitPre.

I don't remember but I think it's possible that PVRTC requires either just one (1) or full chain of mip maps (0).
Either way on OpenGL ES (mobile) all textures are required to be like that (either one 1, or full 0).

Returns false with 0 too.

Please provide the source image you're importing and I'll test this.

Any .png or .jpg. I've tested with 6 images with same result, can't import if mip maps is not 1. This one for example.

Thanks, this is related to your texture being non-pow-2 which is a requirement for PVRTC, I'm checking if I can handle that automatically by the engine.

However in your case you should import to original type (-1) and then resize with copyTry to PVRTC and set pow2 sizes.

Also please use the Editor for managing assets, I'll fix that for the editor as well.

Thank you for reporting the issue, I've managed to resolve this (it's available in the source now and will be available in next Binary release).

Thanks!

On Mac, conversion works with any mipmaps number.

PD: New PVRTC4 library that you introduced in EE2.0 is awsome, it has much more quality, In my game for ios I can use pvrtc4 for most of textures reducing 120MB in ram! (270Mb => 150Mb now) and it is faster loading.

That's why it's always recommended to stay up to date with latest EE versions

Perhaps on Mac it works because of OpenGL and some ability to create textures with more mip maps than they can support normally.

I use even PVRTC2 for 3D model Textures, and PVRTC4 for most of 2D Gui Images.

Hi, The editor will automatically choose the best possible format for each platform - you don't need to do anything at all.
