I have tried everything I can think of and all the solutions I could find on forums, but I haven't been able to fix this problem. I have a point light that is shining on several spheres which are casting shadows. The shadows work fine, but they are quite obviously pixelated. How do I get them to be smoother?
These are the settings that I took this screenshot with. I've tried tweaking most of the them, but it's possible I wasn't using the right combination to get the smoother shadows.
You're reaching the upper limits of the built in lights. The alternative is to create your own (rather complicated, it's a combination of shaders, materials and scripting) or find a replacement on the asset store (pretty simple, may be money involved). There are also post processing effects that can help a little at the cost of performance (take a look at Unity's Post Processing Stack as a starting point).
Unity lights are made for the general cases and they cover a vast majority of use cases, while still having great performance, supporting a large number of lights and producing fairly quality light effects and shadows. But they're not for every use case, if you have a higher standard of quality, you'll probably have to go beyond the built in lights/shadows.
