I like the look of the water textures and wave animations in REX2, but I wanted to know something before I make a purchase decision. In short, if I only want to use new textures/effects/animations etc. for water and clouds, can I do that? I don't want it to start messing around with runway textures, landscape textures (I use UK photographic scenery), or other stuff. Is this possible?

Yes.

I use the REX2 clouds and water with the horizon uk photo scenery and it looks really good.Recommended

you can select the textures you want to install. Don't worry you will not mess up anything

Thanks, guys. That sounds good.
