When you’re just about finished a model in 3ds max, sometimes a quick clay rendering is needed.
You might need an early prototype for the model. A clay rendering is very fast (especially compared to Mental Ray or V-Ray, which can take a very long time to render).
To set a clay model for rendering, follow the steps below (depending on your version of 3ds max, things might look a bit different).
To make a clay model in 3ds max:
Set all model objects /elements to Standard grey.
Set the render to Default Scanline Renderer.
Set the Light Tracer to active.
Set <no exposure control> for the output.
Place a white plane below the model.
Add a Skylight to the scene.
Then Render the model
