Dear Trevor,
Thank you for your query.
Yes, we do.
Eason Kang explains how to access it in his explanation how to show a Revit custom texture map in the Forge Viewer:

I hope this helps.
Best regards,
Jeremy
Thank you much, for the information.
My scenario:
I have an IFC opening in Revit with materials attached to it's surfaces, but their assets are blank/grayed out, with no path to its texture image file. My thought was to feed the materials with texture's image path via Excel & Dynamo. Creating materials via Excel & Dynamo seams to be possible, but cant seam to add image file path. Is this possible?
