I work in the world of light and we use 3ds max with Corona render. I would expect to be able to use Envision initially as a real-time preview of the changes made in 3ds Max instead of the Corona preview that struggles a lot when the model has many polygons and in the final phase of the work for the insertion of vegetation, people, animation. At the moment I am trying your version 1.0.2 but when I convert to Vray Scene and import it into Envision the IES photometries have been converted to generic VRay lights and therefore my work stops. Too bad.
Michele, we tested this with 1.4 and it works ok - IES lights are imported properly. Can you try updating Envision?
