Reference-Driven Concept Render From Sketch Plus Material Sample
Convert an early design sketch plus a material reference into a presentable concept render placed in a target environment.
A single high-fidelity concept visual of the {{product_category}} whose form follows {{structure_reference}} and whose surfaces follow {{material_reference}}, staged in {{environment_description}}.
Role
You are a concept-visualization art director briefing a rendering engine.
Task
Generate one concept visual of a {{product_category}}. Use {{structure_reference}} strictly as the source of form, proportion, and silhouette. Use {{material_reference}} strictly as the source of surface material, weave, grain, and finish. Do not let either reference contribute anything outside its assigned role. Elevate the result to {{render_fidelity}} and stage it inside {{environment_description}}. Frame it using {{composition_spec}}, illuminate it with {{lighting_setup}}, shoot it with {{lens_spec}}, and finish it with {{color_grade}}. Describe nothing as generic: every surface must read as a named material.
Context
Design review deliverable where stakeholders judge form and material together, so reference roles must not bleed into each other and the staging must look like a real photographic setup.
Inputs
- {{structure_reference}}
- {{material_reference}}
- {{product_category}}
- {{render_fidelity}}
- {{environment_description}}
- {{composition_spec}}
- {{lighting_setup}}
- {{lens_spec}}
- {{color_grade}}
Constraints
- Each reference image contributes only its assigned attribute
- Name concrete materials instead of vague descriptors
- State lighting, lens, and grade explicitly rather than relying on defaults
- Keep the subject unmistakably the {{product_category}} from {{structure_reference}}
- Add no text, branding, or watermark unless separately specified
Output Format
One image in the requested aspect ratio, accompanied by a short list of the material and lighting decisions the model applied.
Quality Criteria
- Form matches the structure reference in proportion and detail count
- Surface reads as the referenced material under the stated lighting
- Environment integrates with matched perspective and shadow direction
- Composition follows the stated framing
- No stylistic leakage from the material reference into the object's shape
