Before exporting a 3D view to FBX, do the following:
- Apply materials to model elements.
- Specify the desired render appearances.
- Check the placement of lights in the view.
- Dim or turn lights on or off to achieve the desired result.
- Follow best practices for rendering to optimize the results.
Before exporting to FBX to render in 3ds Max, you may want to generate an initial rendering using the native Revit rendering engine. By rendering in Revit first, you can check lighting and material render appearances, and refine them as needed before exporting. See Rendering an Image.
