Discounts or lower rates for Architectural Renderings

Yes, architectural illustrators and rendering studios generally offer discounts or lower rates if the client provides a complete, usable 3D model. Supplying an accurate, well-structured 3D model (e.g., in SketchUp, Revit, or Rhino) reduces the labor-intensive modeling phase, allowing the artist to focus directly on texturing, lighting, and composition. 

Here is a breakdown of how providing a model affects pricing:

• Significant Time Savings: Because the artist does not need to build the geometry from scratch, production time decreases, typically lowering the overall rendering fee.

• Reduced "Modeling" Costs: A large portion of a renderer's fee is spent on the initial 3D modeling effort. By providing the model, you eliminate or reduce this line item, which can lead to lower, more customized project-based pricing.

• Quality of Model Matters: The discount is often contingent on the model being "clean" and ready for rendering. If the file requires significant cleanup, conversion, or detailing, the savings may be reduced or eliminated.

• Focus on Texturing/Lighting: The fee will transition from a "build and render" price to a "lighting, texturing, and rendering" price. 

Key Considerations:

Upfront Communication: Always mention that you are providing a 3D model when requesting a quote to ensure the savings are reflected in the initial proposal.

File Format: Ensure the file is in a format compatible with the illustrator's workflow (e.g., OBJ, FBX, SketchUp, Rhino). 

While some, particularly lower-cost providers, might not reduce their prices significantly, reputable professionals will generally adjust their fees to reflect the lower labor investment.
