Interior Box Mapping (Blender Shader)

This blender material allows for interior mapping rooms with cubes inside onto 2D flat planes.

The material runs well both in Eevee and Cycles.

Attached in the blend file inside the material are customizable node groups for the room and cube. The cube node group can also be duplicated to add multiple shapes inside the room. There is also a node group called virtual lights that simulates a fake ambient occlusion by multiplying a gradient over top the textures.

Feel free to use this in your projects! No payment necessary but donations would be extremely appreciated. :)
