Hi. I’m brand new to Unity and am hoping I can get some help.

I want to make a 2D game with a world map (fixed camera) with selectable countries/regions and am following the advice in this thread:

As I understand it, in order to do a Raycast on my texture world map, I must first make the map readable, which is what I’m having trouble with. In this thread…:

…it is said that I must use TextureImporter to change the read/write setting of my texture, but I can’t figure out how to do that. Would anyone share their expertise and tell me how to use TextureImporter to re-import the png image I want to use as world map? Thank you very much for any and all help.
