  • Closing as no .capx provided (it is mandatory).

    Note that the behavior you describe is by design if you choose "High quality" downscaling mode. If you had provided a .capx, I would have been able to verify that you had chosen this option.

  • This is how "High quality" has to look like? This doesn't make any sense to me, can you please explain.

    It was exported as high quality Full screen and down scaling.

    It was exported as high quality Full screen and down scaling.

    This should have popped up when you picked "High quality":

  • Yes, in order to produce absolutely flawless downscaled images, it is necessary to pad them to a power-of-two size and repeat the last row and column of pixels across the image area so that mipmap generation never exhibits artefacts. However it is rarely necessary and "medium quality" suffices just fine for most games, and doesn't go to that extreme. Construct 2 now prompts when you choose that mode because you aren't the first person to choose the option without being aware of its consequences.

  • Thanks for the reply, but I still don't understand why you need to pad them to a power of 2 to get a better quality.

    All my images are a power of 2 and the reason I wanted to export to high quality is that I blow up my images in the game to keep the download size small, most of my images are 32x32 and 64x64 or 32x64 etc. and blow them up as 64x64 to 128x128 etc.

    (maybe I don't understand it all right because English is not my first language)
