I've been trying to make an object fade from one end in cycles, sort of like a gradient of transparency. I was wondering of anyone could help.
Here is an example of what I want to achieve in terms of transparency:

  • $\begingroup$ Can you clarify what you mean in terms of your end goal? Are you trying to animate something that goes from solid to transparent? Are you trying to make a still shot do this? This will affect the quality of the answer you get. $\endgroup$

You can use an object as mapping coordinate for a coloramp, and by moving it around you can tune up the effect or transparency which is obtained by mixing a transparent and a diffuse shader in this case. Just an example. enter image description here

You can also use the generated mapping coordinate depending on your geometry. In the last picture i had put the object used for mapping a little backward in the scene. Here the input is a texture coordinate node and the mapping is slided on x enter image description here

    $\begingroup$ I find this image confusing. Making the object stand out from the background would help clarifying your answer $\endgroup$
