Thank you... and the talking of some not yet xp-ready competitor is what me made think about this stuff. I have some thoughts about that talking and the expectations they create in the community just because of their general company reputation. I think those competitors until now did some very different stuff (injecting weather, injecting textures, minor visual tweaking of the default weather rendering) and this approach, as long as they are going to use the default weather rendering, won't bring the same results in XP as they do in ESP based sims (in my opinion, of course). Exactly, I think just positioning clouds and changing textures is something we can have in X-Plane already, and further most of the stuff is freeware. And, even if they could create good visuals, they will very likely run into performance troubles as the defaul weather is performing poorly as soon as there are many clouds on the screen and the airplane gets close to them.
I had the RWC cloud layer stuff somewhere in my mind, but I had to ask for a clear answer to really know what I am talking about in discussions.
