How to make light go through walls

Hi there.How can i make the light go through walls,so the light will not be stopped and make dark in the building.Please help me,thanks

That will make your scene unrealistic. Tricks people use to avoid places from being too dark:

  • Add other lights inside the building
  • Add a weak light in the player character, so wherever he goes will always be a little lit without affecting the scene from far away(e.g. Dark Souls)
  • Put a very small amount of emission in the materials, but that tends to look a little weird

It may be unrealistic but i want to see how it looks,because i tried the options you said,but is not what i want

Hi!

Just in your light’s settings turn off cast shadow!

thank you very much!
