Troubles rendering the materials of an Arnold procedural

[Andrea_Martinelli]

Hi, this is my first post, I hope someone can help me! I am currently having troubles rendering the materials of an Arnold procedural containing an asset. I created the first object wich is a single object consisting of three different elements, each one with a differente ID and a material assigned to that ID. When I try to render with Arnold the second object (represented by the procedural) appears without any shading (I already checked the asset export page and the "shader" voice is checked)

"Without any shading" means flat gray?
Then it could be missing textures, if all the colors are driven by textures.

Can you post a detailed Arnold log? See the

Just to make sure I understand:

• There is one geometry object, with three shaders applied to different parts of that object.
• The shapes and shaders are exported to an ASS file (or ABC or USD?)
• A procedural loads the exported file.
