This is the cave with the red boxes and materials in the south with all the waterfalls. It clearly has a solid ceiling, yet further out areas appear lit by sunlight. It's like only a certain radius from my character actually takes the cave into account. This happens even in the tunnel leading to it. It's probably my PC needing an upgrade, but I figured I'd put it up anyways. pso20210514_220716_003.jpg pso20210514_220719_004.jpg pso20210514_220729_005.jpg
