mbSkyScraper

This HDA generates Skyscraper Buildings from Perpendicular Rectangle Shapes or Box Inputs. At the moment the input must be in perpendicular angle to World XYZ Direction.

If the Input is a 2d Grid you must add a @zscale Attribute to define a base Height of the Building. These can be setup with the Attribute Randomize SOP.

Quick Setup 2D grid input:

• Create a Grid with 3x3 Rows.
• Add a Attribute Randomize SOP @zscale with min (20) and max (90)
• Plugin to the first input

Quick Setup 3D Box Input

• Create a box at the size around 10-100 units. (Default value 1x1 wont work as the box will be too small to create a building from it.)
• Turn on Use Box Input on the Settings of the HDA
• Plugin to first input
• Whitebox as many Boxes you want and pipe them thru the HDA to generate Buildings.

The Standard Assets that come with this HDA use a 8x4 unit size tile by default. You can customize these Parameters and model your own Windows and Doors. Dive inside the asset and it will take you inside the Assets subnet containing all the Models.

Adding Billboards and Store Signs

For Billboards and signs we use a Texture Atlas Workflow. We create a Texture sheet in a 2d Graphic Application and import that into Houdini on a 2d plane we then cut according to our texture sheet. You can then input this Sheet into the Billboard Subnet Procedure and modify the look of your billboards further.

Important: Dont Change the Name. The asset will look for ./ASSETS/billboards and store_signs In a future release we will expose the location parameter so the user.

This Asset works in a Grid Fashion so it only works with Inputs that are Perpendicular to the World XYZ Direction.

This Asset does not work with the Parcelling and Lot Generation.

However it will work with the mbOBBSubdiv as long as the Input and Output from the OBB Subdiv are Perpendiculat to World XYZ.

This asset can be used with the mbCacher and mbBuildingPainter Shelf Tool

• Sometimes the Winding Direction gets messed up (Known Resolve: Add Option to Dev/Hack and expose the Fix Windings Direction from mbDecorator)
• Asset Fails to cook when Geometry cant be Loaded.
• Interior setup is only in RND stage and might not work correctly.
