Blender Previs to MiniMax H3 Anime Workflow

Workflow: 1. Use GPT-6 Astra with Blender to create a simple 3D previs video (camera path, timing, scale, blocking, environment geometry). 2. Export that previs video. 3. Feed the previs video into MiniMax H3 with a character reference image and a prompt. 4. Instruct MiniMax H3 to replace placeholder objects, populate the environment, and transform the scene into a polished 2D anime sequence. The previs acts as a moving blueprint, so the video model focuses on character, animation, and final look instead of solving everything from scratch.
