I've got stuck with 'pixel per unit' parameters and object scale.
I've created two different sprites. A background picture, 1000x1000 pixels, and another one for a 'player', 200x200 pixels. I've added two empty game objects, with default transform, so positions are (0; 0; 0) and scale is (1; 1; 1). I added a sprite renderer to both of them, and assigned the required sprites. Both sprites have 1 pixel per unit.
And the 'player' in the scene looks much more bigger than the background.
I expect that if ppu=1, then the background would have a size of 1000 units, a player 200 units and it would be 5 times smaller.
What am I doing or understanding wrong? What is an actual object size?
