(This is no longer an issue with the release of 1.5.10.25 version of Texture Unlimited, However this version of Texture Unlimited needs to be explicitly selected in CKAN as it is officially designated for versions beyond 1.8 only. Proc tanks appear black in the editor sidebar.These are the issues you will encounter if you follow this guide exactly. Note: The following is an incomplete list Neph is putting together as he remembers things. This same guide is also available in video form, thanks to Carnasa. Don't be intimidated by the length the extra words are to better hold your hand through the process. Unlike previous guides, this is a complete guide to install not only core RO/RP-1 but also the essential extra mods used alongside it. Not following this guide to the letter will break things and make you very frustrated. Please carefully read and follow every word of this detailed guide. No support will be given for 1.8 installs. Please move to KSP 1.10 and accompanying versions. This version of KSP & KSP-RO is no longer supported.

Welcome to the installation instructions for RSS, RO, and RP-1 on KSP 1.8.1.
