Hello, I have added a few different materials to my model and all of them are visible in Real time render mode - both in Standard and Lumen, as well as in the small windows with saved scenes in Media mode.

However my aim was to make the renders with Path tracer, but no materials (I tried a few) can be seen on one specific object in my model when Path Tracer is on (I’m talking about the main blue walls in the model, see attached pictures).

Am I doing something wrong or is the problem related to my laptop/Twinmotion settings?

PS: This is just a quick model to illustrate the problem, so don’t mind the aesthetics of it. 🙂
