How can I use User Data in Octane Materials?

[Delizade]

Hello,
I need to use user data in my octane material. How can I pull data from user data? (and I can't use xpresso for my scene)
I need to pull file name information for normal texture maps for every objects. Single material is assigned to 200 objects. Only difference is normal textures.

thank you

You need to use xpresso, why you cannot use it?

thank you for your help

I have to share some samples to explain but it will take time so I can't share right now.
I hope we can solve this kind of needs inside materials rather than "outside" ways :/

thank you again
