First let me say WOW!!!. I really love this Sim. I've done all the Terrains, Add-on Aircrafts, and FM's over many late nights, but I need help with the Clouds Mod. I don't want my house of cards to tumble down again. Do I need to create a sub folder, say ENVIRONMENTSYSTEM in my Flight Mod Folder for the Cloud1.targa and config. files for it to work. Also another problem, on the Sopwith Pup in the Cockpit view the fusealage interior framework or ribs shows white. I read the sticky on this but it doesn't seem to apply in my case. Does anyone know a fix for this as it is one of my favorite Planes from my Red Baron 3D days. Thanks to all who can help.
