NEW QUESTION: I have, instead of using a preset shader configuration, gone to the Advanced Settings in the 'Environment' options for the server; I changed ambient color, shadow color and basically made everything dark in color. This creates the same effect, but does it allow users who have shaders turned OFF to experience it the same way? (i.e. unable to see a player against black surfaces, lights penetrate the darkness, hard to see in darkness, etc.)?
