You’ve probably seen or heard about the interior effects from the latest Spider-Man.
First, it is worth noting the artist is using Unity 2018.1 in this case but you can use any version from 5.x to 2018.x.
Before you start, make sure the Reflection Probes Box Projection option is enabled in the project settings. Not enabled? Go to Edit / Project Settings / Graphics, uncheck the Use defaults option and check the Reflection Probes Box Projection on all the tiers.
You’re now ready to start, and you can use 3D models made with Asset Forge, for example, one for the interior and one for the exterior with a few color variations.
