Ultra-realistic environment from a tutorial

The workflow behind a 13-second shot of a Porsche driving through a sunlit forest (2560x1440, 390 frames). The big idea: don't ask Claude for a scene. Give it a long tutorial and let it follow the tutorial step by step. Claude writes the code and places the cameras. The tutorial's free assets and open-source tools make the models. Every script in scripts/ was actually run for that shot. Names inside them (forest.blend, his material and collection names) come from that scene - rename them for yours.

Rules for Claude

• Do not build 3D models or animation from scratch. Use the free assets that come with the tutorial, or open-source ones.
• You are good at code and cameras: scripts, scatter systems, camera moves, render settings. Do those.
• Write your own code. Do not install add-ons or run scripts you did not read. (The paid Geo-Scatter add-on and the Rig-A-Car add-on were both replaced by our own code.)
• After every stage, render a small test still and put it next to the reference frame. Fix what is off before moving on.
• Hand render-and-compare loops to a cheaper sub-agent (Sonnet) with a tight brief and read only its short report. Saves tokens.
• Tell me how long a render will take before you start it. Keep the PC usable: below-normal priority, 8 threads, texture limit 2048 for tests.
