That surreal PS1 era of 3D graphics is ideal for the occult. So much of occult art is attempting to explore the ineffable, to depict something beyond words. That era of 3D art was dominated by the rapid onset of powerful new technologies. It was an artistic peek through a keyhole into a grand imagined future. Magic and vaporware go hand in hand.
You get me.
Early 3D art was concrete enough to represent the things they were trying to represent, but still crucially abstract enough to allow the readers imagination to flood into the gaps.
Even the earlier half-generation of 3D allowed artists to create surreal dreamscapes that would be at home in any grimoire or alchemical text.
specifically in reference to game development, popular engines have become so advanced and the push for hyperrealism so strong that occult art and games have become oversaturated with blood and gore, which completely discounts the fear that comes with the uncanny valley, liminal spaces, and disconcerting binaural audio and the weight that these aspects can have when it comes to making something genuinely unsettling, odd, and memorable.
The purpose of occult art is not necessarily to scare or frighten or unsettle. It is to communicate an incommunicable idea. In my opinion, yhe goal of occult art is to induce wonder, to induce awe.
