Ken….. are you on…..a mac? Windows latest Red ver is 3.04.xxxxx
Sorry but you’re right, the file may not work (cross platform).
Anyway, as I wrote above, on the text 3d track select the textures tab and put an X in the faces you want gradients on. Now twirl down to the texture track and click on the track media icon and from the drop down select ‘gradient’ as the texture track media and adjust as neccessary.
good luck…
