By default, every object in your scene is considered to be opaque. There’s a very good reason for this, it helps speed up renders considerably. But if you’re new to Arnold, you may have found yourself scratching your head when trying to render transparent objects.

Setting up transparent objects in Arnold is easy:

  1. Select your transparent object and assign an Arnold Properties modifier to it.
  2. Under General Properties, enable the General check box…
  3. And disable Opaque.32-transparentobjects-001.jpg
    As this is a frequently asked question we have provided both the question and answer in this thread.

An alternate method is to use the 3ds max Physical Material. It translates to Arnolds "standard surface" under the hood, but does manage things like the opacity flag automatically.
