Question by savante_2 · Apr 12, 2019 at 07:32 PM · lightingshadowdirectional lightlow polycrosssection

Lighting for side section view

Hello All,

I have a 3D cross-section scene which has several tunnels on top of eachother and open land, shown in isometric view. I am using directional light for lighting the land but then every level is casting shadow to the level below. I want the shadows but not from upper tunnels, which wouldn't happen in reality. I am using a colourful low poly design and I want everything visible and well lighted. What is a good lighting solution for a mobile game in this setup?

If you don't need the roof of each tunnel to shadow what's inside, you can just set 'Cast Shadows' in the tunnel's MeshRenderer component to 'Off'

Thanks for the answer, it really works up to a point but when I set cast shadows to 'Off', the objects above the roof start casting shadows inside the tunnel like the roof becomes transparent. Is there a way to stop it?

You'll just need an object for the top part of the roof that you can set to have shadows
