fading transparency on reflective floor

Can anyone help me with a small problem I'm struggling with?

I created a reflective floor and have an object standing on it. I want to use a circular black to white gradient in the opacity channel to fade the floor and reflection away at the edges.

Can't seem to get it working. Any help gratefully received!

Hi Mitchino,
Not sure what all you've tried, but you should be able to accomplish this with an image texture or a c4d gradient texture.

Hi mitchino,
probably an issue with projection, firstly plug the texture in diffuse before using it in opacity, it should be more easy to visualize.
As niestudio pointed out, you can use a texture or a gradient shader, but please, avoid to use the c4d Gradient shader, and prefer the Octane Gradient shader instead. It does not need to be baked, and there is a Radial shortcut that creates all the necessary nodes, just correct the projection:

hi how can you do this in 3ds max
