  • Installed Arnold for 3ds Max.
  • Set up licensing (if you plan to use your 3ds max on a render farm or render from the command line or with Backburner, you will need a license for MAXtoA).

 


1. Start 3ds Max.

2. Arnold should appear as the current renderer in the Render Setup dialog (from the top menu bar, Rendering> Render Setup..., or by clicking ), set Arnold from the Renderer drop-down menu.

  • We can choose an Arnold light from the Lights tab in the Create Panel. 

    Center

  • By default, a quad_light will be created. Change it to a point_light. Position it so that it is above and in front of all of the objects in the scene.
  • Now we need to increase the exposure of the light. Select the light, and under the Modify Panel, you should see exposure. Increases it to around 14Try adjusting its value to see the effect of the lighting in the scene.

Arnold Light Type: Point. Exposure increased to 14.

...

  • Now we’re ready to do a render. Start an Active Shade render by clicking on the icon. If you do not see this icon, hold down the mouse and on the flyout choose the 'ActiveShade' button.

  • You may still find that the scene is a little dark for your taste. It's worth mentioning at this point that lights in Arnold use quadratic decay by default (because that is what happens in the real world, and Arnold is designed to work with a physically accurate approach to modeling and lighting). You can also address the 'too dark' issue by altering the intensity of the light. Generally speaking, we recommend you work using the quadratic decay as it is more realistic, so you should choose intensities (and the scale of the model) accordingly, and then use the exposure setting to fine tune.
  • If you increase the Radius of the light (select the point light and increase the Radius), you get soft shadows. Increase the number of light samples for the point_light from 1 to 3 to reduce noise in the shadows.

Increasing the specular_roughness blurs the specular reflection or the sphere

The result of all these changes is available instantly in the Active Shade window so that you can work interactively, changing materials, and lighting without having to re-render to see the effect of your changes. You simply need to wait slightly longer for a better quality render if you have things set up correctly).

That's the end of this short introductory tutorial. Now that you know how to assign and edit Arnold shaders, and alter Arnold settings of lights, it might be useful to play around with various settings for a few minutes before reading on.
