Ebin Resurrected v1.1

Coloured Lighting

Gone is the screen space coloured lighting from BSL which never worked properly anyway! Coloured lights now use a voxelised floodfill system. This means that even lights that are offscreen can contribute to the colour of light sources! Note that currently, light colours can leak through walls. I am aiming to fix this in the next release

Reflection Improvements

• Reflective surfaces now use a GGX distribution when sampling rough reflections. This is not only more accurate, but faster than the old method.
• Reflective surfaces will no longer mix the reflected sky with black based on the light level. Instead, they will blend with the original colour, meaning that reflective surfaces look non-reflective instead of extremely dark when underground.
• Rough surfaces now look rougher in reflections as it turns out the roughness was being incorrectly squared twice.

Other Changes

• Fixed issue with capitalisation on water fog include which would cause the shader not to load in most cases
• Improved water fog (again)
• Improved iPBR for light sources
• Removed directional lightmapping on skylight as it does not work well in the current state
• Tweaked directional lightmapping
