I forgot to mention that in REX Settings you have to choose your simulator, so you have to point to your p3d v4 root folder and if you are using any weather engine do the same. I am using AS16.
Regarding p3d itself i don't change anything in his settings. I think the weather rex options are just a simple preset of clouds and weather textures but im not sure.
Btw these are the first steps to do after install REX.
