About the Rendering Workflow

T
Written by Tim Sublette

Lights and materials can be added to a 3D model before photorealistic image is rendered with the program's renderer.

The following outlines the basic process of setting up a 3D model and rendering a photorealistic image from a scene.

Task

Related Commands

Create a 3D model containing the objects to be rendered with 3D solids, surfaces, meshes, and 3D faces.

Define the views of the 3D model to render. Use named views for consistency and to make switching views easier.

VIEW

Assign a background to the current view.

BACKGROUND, VIEW

Create materials to be attached to 3D objects.

MATBROWSEROPEN, MATEDITOROPEN

Attach materials to 3D objects directly or by layer.

MATERIALASSIGN, MATERIALATTACH

Add user-defined lights or use default lighting.

The LIGHTINGUNITS system variable must be set to 1 or 2.

Enable image-based lighting as an alternative to default lighting, or to fill an entire scene with light and eliminate dark areas.

DISTANTLIGHT, FREESPOT, FREEWEB, LIGHT, POINTLIGHT, SPOTLIGHT, TARGETPOINT, WEBLIGHT, RENDEREXPOSURE

Optionally, enable and define settings for the Sun & Sky based lighting when rendering indoor or outdoor architectural scenes.

The LIGHTINGUNITS system variable must be set to 1 or 2.

SUNPROPERTIES

Set the Low render preset current.

RENDERPRESETS

Render a region of the 3D model to test the attached materials and lighting.

RENDERCROP

Adjust the materials and lighting in the scene based on the results of the test rendering.


Set the rendering environment and exposure settings.

RENDEREXPOSURE

Create another test rendering; make any desired changes to the materials, lighting, and general rendering environment settings.


Set a render preset with the best rendering quality desired current and create the final rendered image.

RENDER, RENDERPRESETS

Save the rendered image to a raster image file.
