Make a city (and add a roof)...more on the Houdini building generator.

In this video we add roofs to our building and enhance what we did last week with a single “box” building to create a “city” with multiple types of buildings (in this case two.)
The random building setup comes from this pixel fondue video https://youtu.be/r9hr3j_Qap4

The roof setup comes from this video from the same series we talked about last week:https://vimeo.com/715332199?embedded=true&source=vimeo_logo&owner=1723479 I made the pitch a little less aggressive but the principles are the same.

Finally we discuss the status of using the Houdini Engine plugin in UE 5.1 with the building generator tools..

NOTE on the point method. I did some further research (created an empty switch node to see what it says when you try to use the method). It is point(<path to the surface node>,point number,attribute, index - current position in multi-part attribute) so point(-1,0,”index”,0) means n/a for the path to the surface node, point number 0,”index” attribute (on that surface point but in our case just our defined attribute), first part of attribute)
A surface node is the node that defines the geometry…since we’re looking at an attribute we created, not a surface, -1 most likely means “not applicable”.
