displacement is not working on MaterialX look assignment.

Hi,

I am using .mtlx file to assign look on the mesh.

I exported the .mtlx file using arnold rop node. When I connect look through materialx node, Look assignment works great, I got the exact look but displacement is missing.

There is no error found on the log. It is clean as usual.

Can you please look in to it?

It works for me (HtoA 5.0.0). I tested with a mtlx exported from Maya, which I applied to a procedural.


What's your log verbosity? Set it to Debug to check that the operators were actually applied (eg the selection expression is valid).

I have checked the log. all the operators have been passed to arnold successfully. No errors. I have attached the file link. Can you please check?

I did my own test, from scratch, and it worked.

It's a problem with the geom paths in the mtlx file.

surface shading is using paths like geom="/obj/emily/alembic:6", which work.

displacement is using geom="/emily_geo/Emily_head_trans/Emily_head_mesh", which doesn't work

Yes, thank you so much. It is working if I manually change the value in emily.mtlx file, but One thing I dont get it, by default How arnold writes in the emily.mtlx file displacement ../image1_material_disp_map" geom="/emily_geo/Emily_head_trans/Emily_head_mesh" ? It is suppose to write like ../image1_material_disp_map" geom="/obj/emily/alembic:6".

am I doing anything wrong?
