Hi Houdini labs gang \m/
I am working on a project and we want different side walls to the front facade of the building ( like being able to define just one module like a simple wall for sides) and also removal of the back wall ( for performance reasons of course) , has any one had experience with this edit on the labs "building from pattern" node? I dived in and tried to name the prims in the subnet in there, so at the end I can remove those by an index value but it didn't work any help will be super appreciated, cheers \m/
