Hello, doing a tutorial on heightfields (which is a houdini 18 tutorial) but im working in houdini 20

the tutorial is going over conversion and export of the heightfield as an obj

it is using a fileCache node to do so, however

when I put one of these down in houdini 20 everything is changed and the tabs are different and there is no option for exporting as obj

houdini 18 filecache image and 20 filecache image are attached

The interface of File Cache node has changed since Houdini 19.0, by default it acts in a way where you focus on folder path and file baseneme, then it constructs the full file path for you.

To have more control on the file path, you can change "File Path" parameter from "Constructed" to "Explicit", and write a filename with .obj extension.
