Common Issues

Properties are greyed out on the light component

This is by design. Those settings are driven by the PVLK Light Settings category on the actor, and the component shows them read-only so the two can never conflict. On your own Blueprints using the PVLK light components directly, everything stays editable. More information in the Light Components section.

Runtime changes don't do anything

If you're trying to change properties like Attenuation Radius (All lights), Inner Cone Angle (Spotlight) or Outer Cone Angle (Spotlight), and nothing happens, then changing the mobility should allow you to change these in real time.

The icon changed when I changed mobility

That's a feature: PVLK lights show a different editor icon for Movable lights so you can read your lighting setup at a glance - the same convention as Unreal's built-in lights. Set a Custom Icon Texture on the light if you want one icon regardless of mobility.

The preset dropdowns are empty

The dropdowns list preset data assets. If you deleted the shipped presets (or filtered your Content Browser), create new ones: right-click in the Content Browser → Miscellaneous → Data Asset → PVLK Light Preset (for 5.6 and 5.7), or Data → Data Asset → PVLK Light Preset (for 5.8). New presets appear in the panel automatically.
