These images and videos are from an unreleased project that I had the pleasure of being Environment Art Lead for. They represent a UE5 blueprint toolkit I created to quickly assemble basic architectural structures. This was extremely useful during level design and level art steps as it greatly sped up iteration times when placing dozens of wall pieces to assembling buildings as part of layout work.
The tool takes in pre-defined data assets that reference different "kits" of art content and lays these pieces out along a user control spline. It also provides some basic rulesets for randomizing selections and overriding specific locations for placements of elements like doorways or windows.
Once users are confident in their placements they can "bake" the tool down to individual asset placements and de-activate the blueprint to allow more thoughtful iteration while maintaining the original tool if a non-destructive workflow is required.
