I am not sure why Enscape shows these elements light emitting…
The Revit material is not emitting light.
thank you
Seems like you have applied that material by using paint tool…
Thanks for your report @Giovanni , could you kindly send me the project itself, or just this particular part for me to check out? 
You can upload the project or part of it to wetransfer.com for example and send me the download link via PM. Also, if you apply this particular material to any other object, is it being shown as self-illuminating as well? Thank you in advance!
oops, I figured it out.
Those element’s family was defective. There was no material parameter attached to the element material, so in the project, changing the material of the family would not effect anything…
thank you
regards
