[Blender glTF] Material not working properly

I am trying to create a terrain. I added a grass material that is supposed to tile the grass texture over the whole plane. Looks good in Blender, but after importing it into the sandbox the coordinate mapping goes away.


You have to use UV mapping here, not “on-the-fly” uvs provided by the Texture Coordinates node.

So here, just go to edit mode and do a Cube Projection for example.
