Hi all,

I've been using Houdini for a while now mostly to process geometry pipelines. I recently started working on a pipeline going from Gravity Sketch -> Houdini -> Unreal Engine 5. I made a rough sketch in Gravity Sketch and exported it out as an fbx, and then imported it into Houdini using the File Geometry node. For some reason, it won't populate the shop_materialpath attribute and I don't have access to any of the material slots created by Gravity Sketch. The material slots show up when the same file is imported into Blender or Unreal. I've attached screenshots illustrating all of this.

Is there a reason for this? How can I access this data in Houdini?

I've also tried using File -> Import -> Filmbox FBX and the Labs FBX import but no luck

Thanks!

I encountered a similar problem sever years back. What I did was export a single frame companion .OBJ file. Inside Houdini I import them both and use an attribute transfer to move the materials, and UVs if needed, from the OBJ to the FBX.

Oh yes thanks, that's a great workaround! Got it to work for now.

If anyone else knows why Houdini won't read the material slots please do share
