Hi Bill,
When working with 3D Reflector, you will need to check how the floor layer interacts with the camera. For example, if the floor is sitting flat, parallel to the direction the camera is facing, then you will not see much of a reflection because of the angle of the floor. However, if the floor or the camera is angled then you can see more of the floor and more of the reflection as well. Try rotating the floor layer in the X-axis and update the Reflector plug-in and this should help you set up the angle of the floor that you need.
If you are still having problems, please send the project file to me at ed@zaxwerks.com and I can take a look at your project file and see what you are running into.
Best,
Edward
