In the current build, the ratio of 2D pixels per 3D meter appears to be fixed at an arbitrary value. For instance, if you import a 1x1x1m gltf into the project, it's on the small side and probably not the resolution the user desires. Currently you can work around this by adjusting the scale of individual models within the project, but this can be tedious, especially if trying to keep a consistent scale over multiple project files. It would be nice if the user could adjust this scale, either at the project level or at the shader layer level.
