Intro to 3D in Adobe Photoshop CS6 and CC
Richard Curtis has a detailed post on using 3D in Adobe Photoshop up on his blog.
Here is the intro to his post with a link to the full post further in.
A new canvas is created in Photoshop CC (the one below is 1024px by 768px).
Creating the 3D object
Two text objects are created with letters in each as shown below.
At this point you can set a colour on the text, as this will be transferred to the 3D object when it is created.
Select one of the pieces of text and click on the ‘3D’ logo (marked red) in the tool bar. Photoshop will then turn this 2D text into a 3D object. This same is performed for the second piece of text.
Create one 3D object by Merging 3D layers
When Photoshop creates 3D objects, they are each placed into a 3D layer, as shown below. Ideally these 3D text objects should be in the same 3D layer, this will enable them to interact with each other, share lights etc.
To merge the two 3D layers into one, both layers (marked red) are selected and menu item 3D / Merge 3D layers (marked orange) is selected.
