lights / matinee / performance

I have enabled and disabled a bunch of “stationary” lights in matinee using the intensity parameter.

  • Are we paying for lights with an intensity of 0.0?
  • Are lights using intensity of 0.0 the same as lights using visibility 0.0?
  • Many of these lights have a redX along with warnings that the lights are causing severe performance loss… but I’ve been very careful to ensure that no more than 2 stationary lights are enabled at one time.
  • Can I ignore these warnings? or are they still valid?

Yes, I guess I could run a gpu profile on the scene to determine if various lights states are costing MS… but figured someone might know.
