Illumination of objects under water is same as above water
« on: September 13, 2018, 01:18:15 pm »

I noticed that while in the new version the underwater environement has improved (more scattering and less light under water + water surface reflection now also in rivers) the illumination of objects under water is the same as above water, whereas they should become less and less illuminated the deeper they go below the water surface, depending also on the type of water (clear or muddy, lake river or sea). would be nice if in a future build this could be improved   :-)

Actually i found that only the lighting properties of objects in some lakes is not correct, whereas any object placed at the same level below sea surface displays the correct lighting, that is - more dark than in open air - as you can see by comparing the screenshots of the tatra truck submerged 20 m below sea surface and 20 m below lake surface.
Seems that mountain lakes or high lying lakes are affected by the problem, as if the underwater lighting were determined by the global sealevel. Would be nice if it were linked to the local water surface level.

Yes it's a known bug, waits for a better water/fog/atmo lookup functionality in shaders.

Thanks. Good to know. Can't wait to see what possibilities this upgrade will open. Maybe locally adjust  fog /atmosphere etc.. simulating for example smog in big cities or fog over water bodies...just dreaming.
