A Beginner's Question About Sprite Importing / Memory Footprint

Hey there. I've got png image of size 600 x 1000, and in the import settings, I've set it to 1000 pixels per unit from the original 100, in order to make the sprites smaller and supposedly save memory space. I'm assuming that it should be fine, as I'm changing pixels per unit within import settings, rather than scaling down the sprite afterwards with transform, but just to make sure before I go ahead with this method for other images, will the build/game still have that large 600 x 1000 taking up the same amount of memory (file size of the game itself), or will it save on space as intended?

Sorry if this is a bit of a silly question, but I just wanna be certain about my 'memory footprint'.



Also, any general advice/info on ideal sprite sizes for this style (not pixel art) in unity would be much appreciated.

 

nothing that you mentioned will change the memory taken by that image

pixels per unit wont change it

transform scale wont change it

the only way to make it take less memory is using compression but that will decrease the quality of your image( you may find the decreased quality acceptable or not)

to reduce memory in the correct way you should resize the image in photoshop to a smaller resolution like this

 

ah okay, thanks for explaining. In all likelihood, I'm going to keep the same sized resolutions, so that the camera can zoom in at certain points without the sprites starting to look pixelated.
