ArtCAM Pro 2012 1.1
Introduction
POV-Ray creates rendered images from ArtCAM’s Assembly components. It can be
used to create more realistic rendered pictures.
The POV-Ray function can be accessed from the Window pull down menu in ArtCAM Pro
and JewelSmith. It becomes available when working with Project and Assembly pieces.
When your Project is complete with all components in the Assembly, you can create the
rendered image.

1.2 ArtCAM Pro 2012
Standard Rendering Settings and Basic Steps The following are general settings which should work with POV-Ray for most designs.
1 Display the finished Assembly in the 3D view
2 Set Assembly Material and Shading as desired
3 Re-size ArtCAM Screen to make 3D view smaller and sized as to match size for
image
4 Click ISO View (Isometric View) and Zoom in if desired
5 From the Window pull down menu, choose Render Assembly with POV-Ray

6 On the POV-Ray Rendering panel,
change the default setting to the
following:
� Lights = all expect Sky Point light
� Sky Area Light
� Key Light – left
� Fill Light – right
� Back Light – left
� Floor/Walls = Floor
� Floor/Walls Texture = Plain White
� Sky Environment = Delcam
� Quality = check Anti-aliasing
7 Click Render
The Render may take anywhere between 10 seconds and several minutes.
You will see the render in progress as it creates the image. Do not close this
window as it is needed for the rendering process.

8 Once the render window finishes and closes, you can check your image in the
location you chose to save. It will be a png image file.
All render comparisons in this document are based on the Standard Setting
shown on the previous page.

ArtCAM Assembly Material Settings The following are notes and tips on setting up ArtCAM prior to the render.
Assembly Components and Models:
� ArtCAM file must be a Project (.3DP), not a regular model (.art)
� Finished design must be in Assembly as mesh components
� Suggested to close Models and view only Assembly
� Open visible models are not included in the render, however if the model is
larger than the Assembly it will affect the shading and background
� Delete any large hidden Assembly’s or large Models
� Even if Assembly is hidden, the size is taken into consideration when the
render is created. This will affect the shading a bit and can play a major role
in changing the background walls and textures. If the hidden components
are much larger than the visible Assembly, it is best to delete it from the
Project. The same goes for large Models in the Project.
Image window setup:
� Re-size ArtCAM Screen to make 3D view smaller and sized to match size for
image
� Can resize entire ArtCAM session screen or only 3D view. Image is captured
on size of 3D view. The larger the 3D view is, the better quality the image
but the file size is larger and will take longer to render.
� To run quick tests on different rendering styles, make the screen size very
small so it renders quickly. Then re-size large before the final render.
� Always render while viewing from ISO View
� The Isometric view will consistently give a good render. If you rotate the
model a small amount away from the default view, it might be ok, but a
drastic change may cause POV-Ray to render strangely.
� Zoom into the model so the component looks as desired with the background
Other Settings:
� Set the shading and material for each component piece as desired
� Select the Assembly component and use Edit Object Shading to change the
material type
� The main ring shown in this document is set to Platinum
� Each assembly component can be shaded with different material to create
designs like two tone rings
� Change the assembly material shading Ambient value from 20 to 30
� 20 is a good Ambient value, however 30 will make it slightly brighter

1.6 ArtCAM Pro 2012
� Gems seem to take longer to render, so the more gems the longer the process
� Note the material and shading setup in ArtCAM is not an exact representation of
what will occur in POV-Ray. It will start with the ArtCAM materials and enhance
it using its own libraries. Also note render image materials like marble and
wood will not completely show up on the ArtCAM side, but will appear in the
final POV-Ray render.
Adding in a reflective base Scene:
� A reflective plate can be added into the Assembly to further enhance the final
rendering by adding better reflection and colour
� The Scenes are pre-prepared Assembly pieces modelled to act as a reflective
base
� A Scene can be imported into the an existing Project by right clicking on
Assembly and choosing Import
� The Scenes can also be setup as Component Library pieces for quick and
easy access
� You can make your own scenes by adding in a large flat mesh and setting up the
material to become a reflective plate. To save the scene, export it as a .3DA.
� The scene must be bigger the finished design
� Position your component as close the scene surface as possible
� We currently have 2 Scenes
� Ruby Sapphire Platinum base.3da
� Ruby Sapphire Black Diamond base.3da
� Both scenes contain a plate and 2 loose gems
� The gems in the scene will reflect colour onto the surface of the model and into
the diamonds

ArtCAM POV-Ray Settings The following are notes and tips on setting up the POV-Ray option on the ArtCAM
Rendering panel.
� POV-Ray is an external program and must be selected during the installation
process. It is setup to run within ArtCAM’s interface.
� ArtCAM has an interface setup for basic POV-Ray options
� The POV-Ray software can be manual opened and a large array of options
changed. We will focus on the pre-set option used within ArtCAM.
� Changing POV-Ray manually will require time and testing, a bit of trial and
error as there are an un-ending array of options and combinations.
� POV-Ray will create 4 extra files needed for the render process with ArtCAM. By
creating and using a dedicated folder for all renders, it will not need to make
multiples of these files.
Lights
� Suggested Light settings:
� Sky Area Light
� Key Light – left
� Fill Light – right
� Back Light – left
� Another Suggestion is using Sky Area with different combinations of the last 3
� Sky Point Light is not commonly used
Floor/Walls
� Suggested setting: Floor
� If you have a reflective plate Scene, set the Floors and Walls to none
Floor/Walls Texture
� Suggested setting: Plain White
� Plain White will stay true to the selected shading
� Other coloured and textured backgrounds will reflect into the model and gems
altering the colour
� If a large hidden assembly was in project at time of render, it will affect the
proportions of floor and wall to compensate for the large piece. Most likely
catching only a portion of the floor in the render.
Sky Environment
� Suggested setting: Delcam
� Coloured Environments will reflect into the model and gems altering the colour
Quality
� Suggested setting: Check Anti-aliasing
� Anti-aliasing softens sharp meeting lines creating a nice render

Rendering Reference Chart The following rendering comparison chart is based on the Standard rendering settings.
There are many combinations, hopefully this chart will provide a good understand of
the options.
The original ArtCAM Assembly for this chart is a Platinum ring.
Standard POV-Ray Rendering base values for chart:
Lights: Sky Area Light, Key Light left, Fill Light right, Back Light left
Floor/Walls: Floor
Floor/Walls Texture: Plain White
Sky Environment: Delcam
Quality: check Anti-aliasing
