Hi all,

I'm brand new to Houdini and am currently following along with a tutorial regarding breaking up an object based on an image.

Digital Tutors Tutorial [digitaltutors.com]

I'm having a problem with one of the expressions pretty early on in the Tutorial.

I have a Geometry node, inside of which there is a sphere and a box, connected to a DOP Network node.
Inside the Network node I have two RBD Objects (Sphere and box) and on each of these objects the Tutorial shows that the following expressions need to be added into the SOP Path of the parameters (one expression per object).

'opinputpath(“..”, 0)'
'opinputpath(“..”, 1)'

The problem I'm having is that I'm getting an error saying ‘Cannot find SOP: opinputpath’

I think the Tutorial was made using Houdini 14, so am wondering if something has changed between the two versions (I'm using 15).

Would anyone have any ideas please?

Thanks

Houdini uses the backtick ` for expression, not to be confused with the single quote '.
Try using `opinputpath(“..”,0)` etc…
