I've followed the various tutorials here and elsewhere but no matter what I do, the text object I create does not reflect on the solid color object I create and place underneath the text object. Attached is a screen shot showing the reflection properties etc. Any ideas?
It looks like from your screenshot you have tried to create the perspective of the black banner behind your text using the Four Corner controls.
What you need to do is take your solid black layer and rotate it through to -90 degrees in X in the transform controls, so it is effectively sitting flat on the "ground". Reposition in y to bring down to bottom of screen if required.
Then position your text layer in Y so you can see where it cuts through the black solid. Raise it just above where it cuts through it.
Here's a motion 4 project file with reflection setup if I'm not making much sense.
