In the latest version of Arnold for Cinema 4D, I have been testing the shader application through operators. Everything seems to work fine, except for the displacement in alembic files.
As you can see in the screenshots, the result of the displacement applied to an alembic file added to an Arnold Procedural, is not correct. With native C4D objects and with an ASS file imported into an Arnold Procedural it seems to work.
All shader and displacement application is applied with the same operators diagram.
Can it be a bug?
The alembic was exported via C4D using File -> Export
