Generate a falloff from a Null's Position?

[Walkinghome6]

I'm in a situation where I need several cloners to fade to completely transparent at a specific location in world space. The cloners are animated so I need them to animate into the falloff area. I've been working with a boole, but animating geo into a boole has bad results.

Coming from Redshift, you can do this with the "State" node. See attached video to explain exactly what I'm trying to do.

Can someone help me do this in Octane? Is it possible? Thanks

Hi,
please have a look at here:

You can try with different type of projections, and use a null object to control the Position, Rotation, Scale of the sinwave/gradient.

Thanks so much for the response. I would not have guessed the setup was that simple.

This situation is something that is requested often, where you have a complex setup and the CD is like "I wonder what it would look like if all of that could just fade out this way". Not so easy in 3D sometimes. Thanks

It's easy if you use "C4D gradient" with xpresso. Additionally there are different options as writing osl script. But this is easiest. See picture for setup.

This looks awesome. I need this scene file, lol

It shouldn't be hard to recreate from picture anyway check the scene.

Wow, thank you so much. That is the simplest setup I could have imagined.

I was trying to figure out how you got the gradient into Xpresso, but found out just now that you view the material in the attribute manager and drag the texture tag over. Thanks again, I will probably use this often to feather out complex mograph setups.
