I recently had the chance to see, purely by coincidence, the environments on which people were actually running my scene. In most of those cases, there was no cubemap, so the scene looked different from the screenshots and videos I had provided. Cubemaps are extremely important in a graphics environment, and most of them are offered for free!

I will do my best to ensure that when you run the scene, you see exactly the same visuals that I showed in my videos or screenshots.
