Are you talking about the ASP3D? It does work with V5, NOTE it is still in beta but it's working nicely so far. I have the AS cloud art with it to, not sure if you still have to buy that extra or not as I bought it a year or so ago, but it makes a big difference.
Also not sure if they work separately or not...
So yes, ASP3D and ASCA both work with V5 with new beta version and beta patches. ;-)
Thanks for the response. I currently use ASP3D for the weather, just wasn't sure if ASCA was V5 compatible and I do not own that product. I was thinking of purchasing ASCA if it makes a difference in cloud presentation and can be used in P3DV5.
