Materials not showing in Revit Links

[todoesvacuidad]

Hello there.

Im trying render a project with linked revit files, but for some reason, structural columns that i have applied a custom  material (bamboo) doesn't show.

anyone knows why this happens and how could i fix it?

Im using Vray into Revit 2023.

TIA

Maybe the Columns are Painted.  

I have about 300 other guesses if that one is incorrect.  

Or, post the File so we can not guess.

You have to transfer all materials in links to your model using transfer project standards.
