Is there a way to stop the light going through walls.
Unity stop light going through walls.
Most of the time this works.
Unity is the ultimate game development platform.
Hi all i have a basic pb building and in each end of the room the directional light seems to be shining through the walls even though i have shadows set to two sided.
You can simulate this in shaders or use raycasts to see if the light is behind a wall.
Shadows are the obvious answer however i assume you are using lite and that s not an option.
Since you re using unity free put the plane on a specific layer.
Then click on your light click on the culling mask dropdown then uncheck the layer the object is on.
I am using gaia for the terrain and have the lighting set to afternoon light for those familiar with the program.
You have a point light source behind some walls.
Now the light will not affect the object.
That s why shadows exist.
Although you have enclosed the light indirect light from the light source seems to seep through especially on the ceiling and the floor.
Trying to solve this for each wall section i added a child gameobject marked as static.
I ve sized the collider to be 0 1 larger than the section of the wall.
Set the point light s baking property to mixed or baked then bake your lighting data using the lighting tab.
Note that this will take a long time depending on the size of your scene and the number of lights 3.
Use unity to build high quality 3d and 2d games deploy them across mobile desktop vr ar consoles or the web and connect with loyal and enthusiastic players and customers.
In that case you ll need to be a bit more clever.
2 increase the intensity as you want and you will see that the light is now illuminating just the wall and don t go through.
These options have obvious edge cases that can t be easily resolved.
About 40 of the time i can drive through the walls.
I am in a room where there is no light and i can see the.
I don t fall through the floor.
The layers are the dropdown box in the upper right of the inspector.
