Silverwing: Place Objects on HDRIs Realistically in Octane - OSL Projection Script

MESSAGE: Welcome to my last tutorial of 2024. It was an "interesting" Year with many ups and downs. So I try to end it on hopefully a high note. "How can I put a object (mostly car) on a HDRI so it looks integrated" was a question that I got asked over and over again. So I recently sat down and reverse engineered a cool idea of the Blender AddOn "LilySurface" as a Octane OSL projection for octanes HDRI. While this is still a work in progress and has it's drawbacks, I think it might be already of use to some of you! Cheers and a very Merry Christmas and the best of times in 2025!
