I'm trying to make simple 2.5D maps for an octopath traveller style game. And I find Asset Forge is the best way to create those sorts of maps, for me at least. However I'm running into a problem. When I paint over a custom block of mine with a material in Asset Forge the texture looks like this.

And when I import into Godot the texture looks like this.

In Asset Forge if I set the texture mapping from triplanar to UV map the texture then becomes enlarged and warped.

Does anyone know what's going on and how I can work around this?
