- lighting via light emitting blocks and brightness from the
- manhattan distance to a light source. light levels should be
- cached with each block and only recalculated on update
+ occlusion/neighbor light mixing is implemented, but still linear
+ this could be solved by using a pre-interpolated light texture and
+ mapping light levels to coordinates on that
+
+ also: how could block light affect entity lighting?
+ maybe get the interpolated light level at the entity's center and use
+ that as the light power for the directional lighting shader and use a
+ direction that's fixed relative to the camera?
