I’ve found the answer that it is necessary to insert it in a file ConsoleVaraibles.ini:
r.Shadow.FadeResolution - controls how big the light has to be on the screen before it starts to fade out.
- Default Value: 64
- Can lower this value to keep shadows from fading out at further distances
r.Shadow.MinResolution - controls how big the light has to be on the screen before it finishes fading out, at which point it no longer has cost.
- Default Value: 32
- Lower values seem to increase shadow visibility.
r.Shadow.TexelsPerPixel - Causes a higher resolution to be assigned and then it should fade out less aggressively
- Default Value: 1.27324
- Can increase this value to improve shadow rendering visibility & quality
- Default Value: 0.03
- A lower value of 0.02 or 0.01 greatly increases shadow visibility at far camera distances (seems to have the most impact of all the console commands).
But nothing has changed, what to do?
