Yes, we do have plans to support both for the material editor. Right now normal maps are only supported for the new Revit 2019 materials.
However if you've got normal maps for your material right now, you might want to rename them with an _n at the end of the filename (e.g. myfile_n.png). Enscape will pick that up and interpret it as a normal map
Hope that helps
Clemens Musterle Aside from the material keywords, Is there a keyword list that Enscape interprets similar to "_n = normal maps" that we can use to and name material maps?
No, currently the displacement feature is not keyboard based. We'll definitely think about future options in this regard though.
