Walk through functions (Walk and Look Around)

Alternatively you can try exporting your Sketchup file to Unreal Engine 4. You can walk around interactively (turn on&off lights, change wall colours etc.) inside UE4 as if you’re playing a video game.
Check this video: SketchUp to Unreal Engine -WIP 1- [Gurkan's Villa] - YouTube (That Youtube channel has more videos demonstrating how to export etc.)
