Why some images can be compressed successfully, some pictures can't

Recently, I have been using basisu and KTX software to compress textures, but I often encounter that some compressed images can’t be used. They will show black on different devices. What’s the reason? Is my compression the wrong way?What kind of command should be used to compress images so that Babylon can work normally



Make sure the width/height of your pictures are dividable by 4. Also, if they work on some devices and not on some others, it may be because the picture are too big for some devices (4096x1024 could be too big on older devices).

We would need a repro to be able to help more.
