Thank you for your replies,
If I understand, RD Shade is not compatible with V4.4. That's a shame it's not clear in the presentation of the product on Simmarket. They say in requirements: P3d v4 and v5
I've already tried this update to v4.5 several times, and each time a major issue occured in the simulator: on my system, p3d v4.5 does not recognize any weather engine... So in that version of P3D my sky is always grey... like an ugly calque hiding the original sky. I advised P3D a few months ago, but no replies to help me! That's why I don't want to go there anymore.
If you have another suggestion for me, I would appreciate,
Thanks
Olivier
