Thanks, that solved it, totally forgot to set PPM in sprite collection.
But that brings two more questions:
1- What should I put in PPM? What's the "correct" number? I'm sure there is no "correct" number, actually interested to know what should one set for PPM and what are parameters important to set PPM.
2- How PPM is related to different resolutions of different art assets (1x, 2x, 4x, etc). Is PPM have the same value across different resolutions so if you double your art assets, then PPM still the same? I think it does, just asking to make sure it is.
Thanks.
