Roofs

Buildings can have 2 kind of roof, Flat or Slope.

Flat

Auto-Flat Roof	Will detect top facing faces and treat theam as flat roof.
Roof Material	Material to apply.
Auto-UV	Automatically unwrap the roof using Box mapping method.
UV Scale	Scale of the generated UV.

Parapet

Turning this option on will subdivide the faces horizontally and vertically, if the space allows it.

Parapet material	Material to apply, UV are based on the flat roof’s UV.
Height	Height of the parapet.
Thickness	Thickness of the parapet.
Offset	Push the parapet in or out.

Slope

Apply the ID_RoofSlope to remove the parapet and scatter Rooftiles objects on it.

Auto-Slope Roof	Automatically treat top facing faces that are not perfectly flat as slope roof.
Roof Slope material	Material to apply, UV are based on the flat roof’s UV.
Auto-UV	Generate the UV automatically based on a Box Mapping method.
UV Scale	Generated UV Scale.
Z Offset	Translate on Z axis.
Subdivide Roof	Round the roof.
Extension	Extend the roof.
Extension Angle	Extention angle.
Extension Normal/Flat	Extention flat or following roof normal.
Roof style	Different mode can give different result and performance depending on what you are trying to achieve: Quick Profile: Doesn’t spaw tile but use a profile object to create the roof, The profile can be procedurally generated. Quick Distribution: Simple tile distribution as array. Random: Random distribution. UV (Auto): Use UV to distribute the tile grid. UV (Manual): Use UV to distribute the tile grid, but the UV needs to be done manually. Slices: Vertical slicing method. Subdivision: Subdivide the face to add the files. Precise: Will allign the tile as array and cut the tile sticking out. Can be heavy on performance.

Roof tile	Collection used for the roof tiles.
Ordered/Random	Use object order from the collection or randomly pick them.
Amount	Randomly remove tiles.
Density	Number of lines of tiles on both axis.
Random Transform	Add random transformation.

Mask

Use a mask to control the tile distribution and create patterns.

Use Crease

If a roof edge has a crease = 1, it will spawn an array of object on it.

Crease Collection	Collection used for the crease.
Crease End Collection	Collection used for the tip of crease.
Spacing	Collection used for the tip of crease.
Translate Z	Move the creases up or down.
Extend	Can make the crease longer or shorter.

Procedural Top-Edge

Will try to generate an object along the top edge of the slope roof.

Material	Collection used for the crease.
UV Scale	Scale of the UV.
Radius	Size of the mesh.
Resolution	Number of division to make it more or less round.
Thickness	Thickness of the mesh.
Translate and Scale	Transform the mesh.
Extend	Can make the crease longer or shorter.

Dressing

Will scatter a collection of object on the flat roof.

Collection	Collection used for the scattering.
Density	Distance between objects.
Distance from edge	Move objects away from edges.
Seed	Randomize the scattering.
Include Slope	Scatter also on Slope roof.
Dressing collection	Collection used for the scattering.

Dressing collection

Collection of object to use to scatter them on the roof.

Dressing density

Density of object to scatter on the roof, the smaller the number the less object .

Seed

Randomize scattered object.

Include Slope

If you want to keep your objects only on flat roof or include the slopes.

Modular

The Modular roof system is in beta but can be useful in some case. It works like Lego blocks. The position of the block in the collection is important. And all the blocks needs to have the same cubic dimension. Please look at the Example objects to see how it works. Here is the position list: 0 - Center block 1 - Side block 2 - Corner out block 3 - Corner in block

Modular	Collection of modular roof piece.
Density	Will add more block to cover the roof, resulting in a denser roof.
Coverage	Extend the roof.
Scale	Change roof size.
Constant/Relative Scale	Size mode.

Gutter

Will spawn an array of object around the roof boundary.

Collection	Collection to use for the gutter.
Only Horizontal	Ignore edges incline.
Trim	Trim the gutter.
Z Offset	Translate on Z.
Distance	Move away from the roof edge.
Spacing	Distance between objects.
Fit	Scale objects to reduce gap between them.
Deform	Deform along edge.
