Movable Light Performance

Hello Community,

we’ve got a simple question.
Is it enough to set the value of a movable light to 0 in order to save performance or do we have to delete the object?

Best regards,

Yes, setting the brighness of a light to 0 or setting its visibility to false is the same as not having it (invisible actors don’t update). Take in account that the Unreal engine supports hundreads of dynamic lights with no performance hit; dynamic shadows are what hurt performance the most, disabling shadows on your dynamic lights will generally do the trick.

Many thanks!
