Changes in v1.1.1:
-Headlight shadows: grain, stripes and large dark straight-edged patches on lit snow and roads. The terrain hands the headlight a position that is not on the surface the camera saw, so each walk to the lamp started in the wrong place. Each pixel's walk now starts where its own camera ray meets the depth.
-Headlight shadows: a comb of bars in the shadow of thin casters such as a fence's rail, the worse the wider the field of view. A ray now takes one step per 6 pixels of its length on the screen, 24 to 64.
-Posts, rails, rocks, walls and snow banks still cast. Measured in the game at 4K: about 4 ms a frame with the beam ahead filling the view.
-Weather: heavy snow lagged: it was drawn out farther than the game draws it and its peaks were heavier. Snow keeps the game's distance and strength now; Far rain (rain only) is off by default.
-Skies: Kola's overcast sky and the grey layer of Kola's, Amur's and Zurdania's cloudy days came from a photograph whose clouds smeared during the exposure. Both are new photographs.
-Skies: Kola's clear days had a grey patch with a coloured ring where the sun was taken out, hills drawn into the sky, and a dark notch at the horizon. All three are new photographs.
-Skies: the back cloud band of Kola, Taymyr and five more regions had flat white clouds, cut off straight at its upper edge. They are now two different photographs of shaded cumulus, at four times the size, with no cloud cut by the edge. Two near bands are new photographs too.
-Skies: no cloud band shows a cloud cut flat along a straight line any more (Kola's clear day, Taymyr, Alaska, Amur, Quebec).
-Skies: the five small skies of Alaska, Amur, Belozersk Glades, Scandinavia, Quebec and Switzerland are four times sharper (8192 x 2048).
