Render Workbench

Introduction

The Render Workbench let\'s you produce high-quality images from FreeCAD models, using open-source external rendering engines.

A pure Python workbench, Render is seamlessly integrated in FreeCAD: the whole rendering scene - objects, lighting, materials, camera, etc. - can be described with FreeCAD objects, to be exported to external renderers.

Compared with other approaches based on third-part computer graphics applications, Render aims to:

• Avoid the user to learn another 3D/computer graphics software: everything you need to know is in FreeCAD.
• Simplify rendering workflow and relieve user from any intermediate file manipulation - like import, export, scene retouching etc.
• Make scene configuration persistent and especially prevent rework in an external tool each time the model has been modified.

Supported renderers

At the moment six rendering engines are supported:

• LuxCoreRender
• Appleseed
• Cycles (standalone version)
• Pov-Ray
• Intel Ospray Studio
• Pbrt-v4 (experimental)

Usage

In quick-start mode, after workbench installation has correctly been done, rendering a FreeCAD model is just a 4-step process:

1. Create a rendering project: Press the button in the toolbar corresponding to your renderer and select a template suitable for your renderer (you may start with a \'studio\' flavour, like appleseed_studio_light.appleseed, cycles_studio_light.xml, luxcore_studio_light.cfg, povray_studio_light.pov etc.).
2. Add views of your objects to your rendering project: Select both the objects and the project, and press the Add view button.
3. Set your point of view: Navigate in the 3D View to the desired position and switch to perspective mode.
4. Render: Select your project and press the Render button in toolbar (also available from project\'s context menu).

And you should get a first rendering of your model.

More instructions can be found in the GitHub repository or the online help.

Features

Features include, but are not limited to:

• Lighting: point lights, area lights, sun-sky and preset lighting templates.
• Cameras.
• Material management (using usual shaders: matte, glossy, glass, principled etc.) including textures.
• Batch mode / UI mode.
• Denoiser.
• Halt condition (sample per pixel).
• Meshing control: angular and linear deflections, auto-smoothing.
