# Character reference sheets Pipeline: a nude body render comes out of Blender, the model dresses that body, each garment is cut out, it goes to an image-to-3D generator, and the mesh comes back into Blender. The goal of the generation is **not a beautiful image**. It is the *same body* as the render, now clothed, with every piece legible and cuttable. Everything below exists to protect that. ## Cost rule, before anything else **Never call `create_asset` without asking first.** Every generation spends the user's API credit. Write the full prompt, surface the decisions that change the image, and wait for an explicit go-ahead. This applies to each retry after a bad result too — do not silently fix and re-run. ## Workflow 1. **Measure the input renders** with `scripts/measure.py`. If any criterion in section 8 of `references/resolutions-and-proportions.md` fails, say so and ask for a re-export from Blender. Cheaper than discovering the problem after the image is paid for. 2. **Flatten alpha onto white** if the PNG is RGBA. Alpha often becomes black on upload and contaminates the result. 3. **Build the prompt** using the architecture in `references/prompt-template.md`. 4. **Ask for permission to generate.** 5. **Generate**, one view per call. 6. **Measure the output** and compare against the input (thresholds below). 7. **Copy** from `IMAGE_OUTPUT_DIR` into the character project's own output folder, with a descriptive versioned name: `character_outfit_front_v...
