This is a replacement Skylab mesh for the one included with NASSP 6.4 and features textured solar panels. It works like a charm with the Skylab launch scenario included with NASSP 6.4.
I can not guarantee it's compatibility with other Skylab add-ons, as I have only tested it with NASSP 6.4.
Special thanks to John Graves (aka missleman01) for his OSI licensed open source Skylab mesh. See the Disclaimer-ReadMe.txt file for further details. Please, read the enclosed documentation prior to installing.
