Godot Version

Question

I’m working on a game in Godot for Isometric style. But, I’m kind of stumped and unsure why my pixel/image sizes don’t align. Here’s what I mean:

My TileSet is configured as (X = 256, Y = 128):

Here’s what it’s showing in my TileSet for Setup:

This is the native resolution for the images that I’m using:

I’m keeping an aspect ratio of 2:1. When setting these up in Godot with the correct image resolution in the tileset (X = 512, Y = 256)

This image here is my tile’s lining up when using the (X = 256, Y = 128):

As soon as I swap to the (X = 512, Y = 256) tileset it looks like this:

It doesn’t line up… Why is that? What am I missing?

use X = 256, Y = 128

They should match from my understanding, so I want to know why they don’t. Also, I don’t want to be using margins and stuff to correct the positioning since that can also affect coding stuff a lot.
