UE4 No light visible at the viewport?

Why any type of light not having effect or visible at the viewport?

Hey @Medhat754!

If you go to Show → Light Types are all the boxes checked in?

If so, when did this change happen? What changes to your project were you working on?

Any additional information you can provide will be a big help in solving your problem!

already checked, still no effect of any light source except the sun and skylight

i just optimized the lightmap density to be green in color, and that the first light I put on the scene so i don’t know if I did anything to affect the lights.

Hey @Medhat754,

How did you go about optimizing your lightmap density? Through your static mesh UVs? That shouldn’t get rid of your lights.

Also, from your picture provided, it kind of looks like you have direct lighting disabled. Could that be the case?

Hopefully this points you in the direction you need to solve your problem!

through manual lightmass at details (each object)

no light gives effect except the “Sun and Sky”

also at a new file!

it worked after I disabled the sun position calculator plugin.

The sun and sky light were too bright for the scene, lowering the intensity was the solution
