Hi all,

Would anyone know if it's possible to control an objects surface parameters using a null?

For example, I have an object for which I want to have several variations of (different texture maps applied), and thought that instead of having a bunch of different object taking up valuable storage space I could have a single object with all the texture maps applied using an Octane gradient and then linking the 'input' of the gradient to the rotation channel of a Null, so that when I rotate the null in (for example) 15 degree increments the textures change. The setup is pretty much the same as the random colouring of Instances, but the problem I'm having at the moment is that I can't seem to find a way to get the Nulls rotational information into the input of the Gradient node (incompatible LW/Octane nodes etc.)

Would anyone have any ideas?

Thanks

Typically,

As soon as I pressed 'Submit' I had a thought, and it works. It's a bit of a Kluge setup, but once I'm done sorting it out I'll post a little explanation.

hehe...LOL

the morphogenetic field works!

Yes please mighty please let us know ur solution

> dp kit / motion info

or

item info > octane projection node> octane texture image

or

octane projection node / open XYZ envelope / modifier / add modifier/ Channel follower / click to your null

or



some other combinations...

try it

Apologies,

I completely forgot I hadn't posted the solution. My bad.

As I said it's a bit of a kluge, but it works so I'm happy

The setup can handle as many inputs as needed, just adjust the gradient node to taste

The Attached image should explain it all. Any questions, please do not hesitate to ask.
