Visual artifacts
Below are some visual artifacts that can appear and how to fix them.
Blocky lights

- Lower light intensity, local fog density, volume override intensity.
- Higher anisotropic & softness.
Light banding/acne

- Increase depth bias.
Sun can be seen through a wall

- Increase anisotropic.
Spot/Point lights leak through a wall

- Enable additional light shadows in URP settings.
Pixelated lights on tree leaves
BEAM renders volumetric light on a canvas that is smaller than the screen resolution, so aliasing artifacts is somewhat inevitable but can be tone down so it is harder to spot.
- Reduce Alpha Cutoff value if your tree shader has one.
- Increase Softness in volume override.
- Decrease Intensity in volume override.
- Choose higher quality level in the renderer feature if affordable.
