A free mod for Witcher 3, by DJ_Kovrik.
The More Shadows mod adds shadow casting to certain light sources in the game, such as braziers, candles, lamps, and torches. You can find the mod in the download section of this page. It is also available as a separate download.
This mod changes the lighting of the game world to be more realistic. This is done by adding more light sources, such as lanterns, candles, or even torches.
This mod also changes the quality of the lighting, so that it is more soft and less intense.
You can adjust the intensity of the lighting by using different light sources. For instance, you can use a lot of torches, a lamp, or even the sun.
