Vali Architect Instant Roof

When I attempt to create an Instant Roof the program either creates a flat toped roof or crashes (creates a Bug Splat Crash #110261).
Around every 6Th attempt, I do get a very nice roof. Not sure what I am doing wrong.

Thanks

Are you using InstantRoofNui? Go through the instructions carefully. Getting inconsistent results and crashes does indicate a bug or incompatibility with your system. I’ve never had a problem with ValiArchitects plugins in this way (crashes), though I had trouble figuring out correct settings sometimes.

Knowing what faces and edges to pick can really be a learning curve. Start out making simple primitives and then combine them until you build your knowledge of how things effect different outcomes. You really must study the tutorials and videos on his site.
