Moving windows dynamically

Hi Guys,

There is an empty room model in our Scene no doors no windows no interior.

Here Player can buy Decor from the shop and place them in the room.

In decor we also provide windows which can be dragged over the walls which means we can't have predefined place for windows and here comes the problem:

We don't know how to lit the room through dynamic windows.

Since our walls are solid boxes we need them to have a hole for windows which can be moved with window so the light can work properly.

Player also should be able to add several windows on the wall.

Any helpful links would be thankful.

 

some ideas,

Could modify actual mesh vertices, but can get complicated with many windows (maybe can limit to 1 window per wall?)
https://docs.unity3d.com/ScriptReference/Mesh-vertices.html
Maybe some mesh boolean package from asset store could work also..

Or maybe can try faking it with stencil portal "holes", probably wont help if needs real lights..

Thanks for the Links,

I can add a hole in the alpha channel of the wall's material albedo and change rendering mode to cutout. This way I will have a hole in the wall

But after that can I move this hole with code using tiling or some tricks in the shader?

I know I sound like not professional but this is our first 3D game.

 

Adding an alpha channel doesn't affect the actual 3D geometry. You most likely have to modify the geometry of the model via script (some sort of boolean operation.

There's also Houdini, which allows for procedural modeling and tweaking your models even in Unity:

maybe it could work,
add cutout as secondary texture, with its own UV position, and then move it around..

Or you could also have 1 prefab for wall without windows,
and other prefab with wall+window already cut, then you can move the wall window vertices easily,
since you know which vertices they are..
