What is the difference between Transmission and Transparency?

Typically, you should use transmission for surfaces separating different rooms and transparency for surfaces inside the same room.  Transmission in ODEON works differently than in real life. The sound energy ‘hitting’ a transmission surface in ODEON is not lost inside the wall. This is because transmission and absorption in ODEON work independently of each other. Therefore the volumes on either side of a […]

I can’t find the materials that I have created in the material library.

It is likely that you have associated the new materials with the local room material library, and not the global material library. Try toggling between the global and local room library by pressing the corresponding button in the material list.
