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 pipes and pipe like assets along a spline. This was extremely useful during level art steps as it greatly sped up iteration times when placing dozens of pipe pieces in context of the level.
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 caps and custom pieces.
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.
