OK, I'm working on something that really should be steam-driven, Motion 3.
All I want to do is apply a gradient (from the list of available gradients in the Motion library) into my window. Particle Emitters, Replicators, Text and other Content aren't a problem, but selecting a gradient and then trying to Apply or drag it into my window gives me a big fat zero ...
Please, does anyone know what on earth is going on and how I might rescue this?
Are you just trying to drag a gradient style into the viewer? Or are you trying to apply the gradient to a layer.
If you want a gradient in the viewer, go to your Library tab and then select the Generators category (not the gradient category). Inside the generators category you should see a gradient color generator. Drag that into your project. In the inspector, you should then be able to select the gradient style button and choose the gradient style you want.
