Greetings to all.
I am trying to create this same effect of degraded transparency for a group of objects, all controlled with nulls in Xpresso.
This is the example:

The C4D gradient has a linear 3D mode and a "Global" mode.
But I can't do the same with Octane material, neither with an Octane gradient nor with a C4D gradient.
I have found a more sloppy solution which is to apply a linear projection to the group of objects and animate this projection, but, in my case, I try to make the gradient "appear" by covering all the objects of the null and their materials. It doesn't work.
It would be like a gradient effect that paints all the objects of the group (that already have each one their material).
Any idea? thank you!

Hi,
please have a look at this possible solution:
It works in a slightly different way, one plane is used to position the gradient, while the other one is used to scale it.

Thats a useful rig beppe, TY! 
ive been trying for a while to figure out how "break up" the gradient edges with noise, like its possible in the C4D gradient using the turbulent noise. u think its possible with the octane gradient somehow Beppe?
best,

Hi,
yes sure, you can use an Add node with the Marble node before the gradient node, with the same projection:
