How Do I Make Sprites Overlap Each Other Transparently?

Currently, I’m working on a project where I have a tree sprite, and I want to have that tree sprite on top of another tree sprite. However when placing it on top of each other the tree gets partially deleted. So how do I get them to overlap?mealycolorlessgoitered

change the z coordinate, or make a 2nd tilemap

Yeah I tried to make a 2nd tilemap, but I get a problem where if I make a line of trees, then I need to have a new layer and tile map for each individual tree. Surely there must be an easier way to make them overlap? Also not sure what changing the Z coordinate does.

I’m trying to have a whole section of trees being lined up to act as a border for my player.

if you place tiles on a different z they wont delete eachother
