Bad render quality

Ladies and gentlemen. I need your help! I am new to TwinMotion and urgently need to get a simple visualization of a small house. However, word simple means lack of environment, but not bad rendering. As you can see, the result does not seem realistic and leaves much to be desired. Especially ugly roof. Seems like it’s displacement map does not affect at all. I use PBR textures from QUIXEL and hdri (moaf cloudy 04) with lumen mode. Path tracer does not work. I am sure that my original Revit-model is fine. By the way, Revit could make it better! May be there are some settings I forgott to adjust? Any suggestions for scene improvment? Thank you in advance!

maybe watch some tutorials first and see the different options?
Here’s one suggestion: https://youtube.com/@jamzview4497?si=2WdH30EXccTj-7fP
There are plenty of others also.

you could start from one of the templates (from the home panel) and then import your Revit file. at least lighting and ambiance settings would be ok. then import your Revit file in it
