Single Axis Tracking Production with Backtracker

[Tokoyoshi]

I am running a PVsyst version 6.52 production on a Single Axis (N-S Axis) system.

I know that I am supposed to run the production with the "3D Shading Scene" when using backtracking option. However I found out that I can run it with the selected "Pitch" value and backtracking option without a near shading scene (see attach).

The production that I simulate without the 3D shading scene, what is PVsyst exactly taking into consideration (no shading, no backtracking, etc)?

If you are able to do this simulation without defining a shading scene, this is indeed a bug (the error is not taken into account), we have to correct it.
