How to add ground reflection in ray tracing in WinProp?
May I ask how to add ground reflection or roof reflection in IRT in WinProp?
I created a very simple scenario first, with a 0.5m glass plate (standard building) as ground and a 5m glass building (standard building), as shown in Figure 1. Then the preprocessing was done in WallMan for 3D IRT, and the prediction height is set as 10m for better observation of reflection on the roof and ground. Then in ProMan, I set an omnidirectional BS at z=15m. In Project - edit project parameter - computation - Prediction model settings, I activate the ground reflection, and in Breakpoint, I set a large breakpoint distance of 10000m, as shown in Figure 2. The ground material properties are by default.
Finally, I got the power distribution result as shown in Figure 3, and selected a random point to display ray paths as shown in Figure 4. However, in the 3D view, it is clear that there is still no reflection on the ground, and all the reflection or diffraction points are on vertical walls or wedges, as shown in Figure 5.
May I ask how to add ground reflection or roof reflection in IRT or are there any mistakes in my operation? Thank you in advance!

Ground reflection would probably be included if you have topography in your project, as shown in the attached image.
