+# Ultimate Retro Shader Collection (v1.4.0): Setup Script

+# This script will add the necessary shader globals for URSC shaders to your project.godot file.
+# To run, just click File -> Run.
+# In order to fully register the globals, the editor will be restarted upon running.
+#
+# NOTE: this script CAN'T be used to manage the globals for your game! You'll need to write your
+# own code to handle the values of the globals at runtime.
