Launched on the Unity Asset Store in 2014, SnapAndPlug was a 5-star rated asset for building levels, worlds, objects, and interactive VR experiences. In 2020-2022, I re-wrote it to support VR natively, and to remove 7 years of legacy code (it still had workarounds for Unity bugs from as long ago as Unity version 5.x!).
In 2023 the rewrite is being relaunched as NinjaBuilder3D / NinjaBuiderVR - see the NinjaBuilder page for more info.
