a room i made for mmd dancing

if you can't get the lighting right, try setting up Trilight with Graphics mod. Press F5 to open Graphics mod >in the "Environment" tab (the 1st tab) > down in the "Environment Lighting", press Trilight (it's past all the cubemaps) > mess around with the RGB options for sky/horizon/ground colors; I recommend 180r,140g,180b. Maybe do a little brighter for horizon, like around 220,180,240
