Importing the CAD Data

Select the files and drag them from your file explorer onto the 3ds Max viewport. 3ds Max will then convert the CAD geometry for you. You should see the model appear in your 3ds Max scene (see below).
Select the root 'Appareil photo' group and choose Group > Open (you can also open recursively when you have multiple nested groups).

The scene is simply lit using a studio HDRI connected to the color of a skydome_light light.

Choose Arnold under the Create tab and click on Arnold Light. Click in the viewport to create the skydome light.
On the skydome light, click on Texture and choose a suitable HDR bitmap. An example of a studio HDRI that could be used with this scene can be downloaded here.

To test the lighting, we can quickly assign a standard_surface shader to the camera.

In the Slate Material Editor create and assign a standard_surface shader to the camera.
Change its base_color to black.

Render the scene using the default Arnold sample settings. These settings are fine for IPR test rendering the scene. Do not worry about any noise in the scene at the moment. We will change the sample settings once we are happy with the lighting and shading at the end of production.

Next, we need to change the background environment color to white.

To access AOVs go to the AOVs tab in the Arnold Render Setup window and select Abritary Output Variables (AOVs) Manager.
To create the AOVs, drag and drop the AOVs from the AOV List on the left to the main panel on the right.

Choose the file Type. The default EXR is normally recommended, however, for this example we will use Png as we will simply be rebuilding the RGBA beauty in Photoshop.
Tokens can be used to generate dynamic AOV output paths. A series of tokens can be selected to define the output filenames (e.g. Scene Name, Camera Name, etc.). Add a token for the <Render Folder> output where you want the images to be saved.
Click Render to render out the AOVs to disk.
