[Godot 2] Trying to understand the Material's "Uv Xform"
MeshInstance -> mesh -> Material, there's the Uv Xform matrix, and I'm trying to get a grasp of what it does. I kinda get it, but I'm really confused, as every time I edit the values it doesn't seem to act in a way that makes sense to me, or to act at all.
I made a cube in Blender, and positioned the UVs around a tile in a tileset. I was trying to figure out if the Uv Xform would help me in changing the cube's UVs to point to another tile in the tileset, but not only I'm not quite getting how it works, I'm also not sure if this would do what I'm looking for (what is basically the same as changing the texture region in a 2D sprite, but in a 3D mesh).
I understand that, according to the docs, they're multipliers. But that's about it... Can someone explain to me what each value in the matrix does exactly?
(EDIT: I was also looking for a way to deform the textures, and the Uv Xform kind of also seems like it could do that.)
