Flipped tiles have messed shading

[TheBricktop]

Hello love your work,
im trying to use my old tiles and they had a lot of mirrorable tiles and ive tried to use them that way with tilemap3d but noticed that they have flipped normals and so the graphics only and the shading is all messed up on the flipped version.
Could there be a way to flip only uvs? Also there could be a way to flip in other axes too, like for example those are mainly y axis symmetric but some of them are x axis too.
Edit : Also ive noticed that there is no obvious way to change shading ? Like one of the ways to mitigate it would be to turn off the shadows but i cant seem to find the way to do that.

It seems that the box shape is making the normals behave that way.

Another weird thing happens with textures on box shape with texture repeat: they rotate 90' on the sides and thats less than perfect with x repeating textures like bricks.

Hey there, I was on a long break and on holiday. I will add this to the list. There is a shader that handles shadows and lighting. If you want to play with it,

There is one shader for flat tiles: tile_multimesh.gdshader

There is another shader for box/prism tiles:
tile_multimesh_doubleface.gdshader

And for Box/Prism, you have the option to specify whether the Texture Repeats on all sides. If you enable that setting, then there is another shader: tile_multimesh_box_repeat.gdshader

This is probably a terrible implementation that repeats almost the SAME shader across different files, but I was just being lazy and wanted an easy/simple way to add small changes to each one for the different use cases.
