I do not have a powerful video card and am unable to use the new method of creating 3D text in AE.
Is there a way to use the Shatter Effect in CC2015 to create 3D Text or does anyone have a suggestion.
The online tutorials I have found are for older versions and the steps don't match my interface.
You don't have to use Shatter -- you can use C4D Lite, which comes with your AE version. Doesn't need a fancy card.
If you must use Ray-traced rendering features like Extruded Text then you must put your extruded text layer in a separate comp with Ray-traced rendering enabled and make the main comp Classic 3D so that you can apply Shatter to the nested layer. This warning pops up explaining the limitations placed on 3D layers with you enable Ray-traced rendering. Read it and pay attention.
Otherwise, follow Dave's advice. C4D lite is a much better solution for things like 3D text.
