Global Scale

This is my first ever shader. I wrote this spatial shader in order to have a customizable material for 3D terrain. This allows for scale planning, proportion matching, range/speed calibration and the like during development. There seem to be some visual bugs in the editor after setting some values but moving the view or object fixes the issue somehow.

	uniform vec4 ground_color: source_color=vec4(0,0.4,0,1);

	uniform float primary_tick_thickness:hint_range(0,1)=0.01;

	uniform float secondary_tick_increment:hint_range(0,1e3)=1;
