Hi.
not sure what you mean, since the spline sampler node comes with the basic pcg plugin
THe only code part relevant to this, is when I create the actual spline based on the FBox that defines the basic shape of the room , and an array of FBox that defines the overlapping sections with other rooms(negative spaces), with this I create a corsssection of the room and create the spline points.
I then use this spline to create the walls, and wanted to use the same spline to create the floor.
previously I used to create points on a grid for the base fbox shape, and a grid for each of the negative spaces. then just remove from the first grid what was on the negative spaces grids. but feels like passing redundant data.
