Why is my Tile Palette brush Z-axis inverted?

Hello!

I’ve just started experimenting with isometric views and I’m facing a weird issue. When painting tiles there is an option “Z Position” on the Tile palette brush:


According to the manual a positive value should offset a tile upwards, in the editor there should be 2 squares, a blue one indicating the default Z=0 value and a white one indicating the offset value:
2D_IsoTilemap_8
For some reason, in my editor the Z is reversed, so positive values bring the tile down, as you can see in the picture (blue and white squares are inverted):

Does anyone know what I have setup wrong to get this effect and how to fix it?

Thank you

I’m sort of lost here, I tried:

  • Unity 2022 LTS
  • Unity 6 preview

In both instances I have the same behavior, even on an entirely new project. I tried both URP and SRP but to no avail and different assets as well. I checked if there were odd rotations in the camera, tilemap and grid, but appears normal.

I even tried on 2 different computers and the effect is the same. Positive Z values bring the tiles down instead of up, I’m quite puzzled.

Would anyone have any suggestion or even an idea where to look at?

Thank you!

where in the manual does it say that positive z should go up?

Apparently here:

First picture shows a Z=2 and the tile offset upwards, but even if the two things were disconnected, the manual shows (in the second picture) that altering the Z value moves the white square up. So if I’m interpreting it correctly, things should move up not down. In the opposite case one would have to know the highest tile possible and draw everything backwards, but that seems not ideal?

it looks ambiguous to me, it doesnt clearly state that a positive z goes up, this manual entry is worded as such that it could go either way
