Promote file name at top level

[blobbybarack]

Is it possible to add the promote option for filename into Texture Image Node via the a gear icon button.
I know this can be done via expression but it's not very convinient in shaders with large number of texture.
Thank you.

Hmm, you can't promote the parameter, but you can reference it without problems if you are building an HDA or even to the top octane material builder vopnet using the edit parameters interface window, as you can see in the attached image.

Hope it helps,

Yeah sure i'm doing it this way already. Asking myself why you can't doing it with Octane as it's available in any in others Houdini context.
