Weird shadow problem at long distance

I downloaded a lighthouse asset with a revolving spot light, but when i put it in my scene any object being lit by it in long distance has this weird issue
It has something to do with the shadows because it only happens when shadows are on and when the object is real far from the light, and it looks very bad with an animated light but i stll need the shadows.. is there a fix for this? increasing the lights range doesn't seem to change it..

 

I found that it dissappeares completely only when i turn the spot angle all the way up to max (179), but i can't have it like that in the actual game.. does anyone know why it's happening?

 

Have you looked at the shadow settings in ProjectSettings/Quality?

You could maybe resolve this by increasing the Shadow Distance, though at the cost of some performance I expect.

 

I did, it doesn't change it at all.. i tried changing everything i know that has to do with the shadows and the only thing that fixes it is to turn of the spotlight angle all the way up.. does anybody know why this is happening?

 

anybody?

 

Looks like shadow acne, try changing the light to use soft shadows and mess with the light's Normal Bias under soft shadow settings.

You could also try reducing the distance between the shadow near plane and far plane in Quality settings.

 

Thank you oh so very much
i remembered i saw those values before but i could't find them, just because when the light was on baked mode they simply didn't show, i switched to realtime and the bias value was the one that fixed it

 

IT could also be that your near clipping plane is too small. Try increasing the near clipping plane of the camera to see if the issue goes away.
