B9 Aerospace 5.2.8

 

The mod is in the process of being updated for 1.0.x version of the game. It's a huge undertaking so we can not give you any estimated release date. Please be patient.

This pack adds a vast selection of new parts, introducing new spaceplane components such as new engines, cockpits, wings and fuselage systems, new structural components for orbital installations and colonies, and so on.

The art style of the pack was influenced by futuristic concept art, modern UAV designs, some believable hard sci-fi ideas, DARPA & NASA aerospace research, and by asymmetrical shapes and faceted designs that are nowadays common everywhere from automotive industry to military aircraft.

I have decided not to go overboard with realistic art style or extreme colors: my intention is to make parts which would blend seamlessly with, for example, KW Rocketry pieces.

The goal of the project is to fill every empty niche in KSP part selection and to replace every sub-par component with a new part better suited for the role.

This is the fifth milestone release of the project, now featuring 211 parts (with multiple configurable parts bringing that number to over 300 types in practice) and fully compatible with KSP 0.24.2.

ABOUT THIS LISTING

Mythiq.net hosts no files for it. The download button goes straight to the release file on edge.forgecdn.net, so you are downloading from the author's own host, not from a copy of ours.

The download count, rating and comments on this page start at zero and count Mythiq.net only. The source's own figures are not copied here — they measure a different site, and a number that cannot be checked against our own ledger is not worth printing.

GAME VERSION

Built against KSP 0.90. Parts and plugins compiled for one major version routinely misbehave on another — a plugin for 1.8 can fail silently on 1.12.

DEPENDENCIES

Many part packs and plugins depend on ModuleManager, and some on each other. KSP's loading log (KSP.log in the game folder) names the missing dependency when a part does not appear; the author's page lists the usual set.

1. Download the archive with the button on this page and unzip it.

2. Move the mod's folder — the one containing the .version file or the part folders — into:

Kerbal Space Program\GameData

The path in game must read GameData\\…, not GameData\\\…

3. Start the game. Parts appear in their categories in the VAB; plugins show their own toolbars or settings screens.

4. If the mod ships a CraftNote or extras folder, leave it — some packs store example ships and textures there.

UPDATING

Delete the old folder in GameData first. Two versions of one plugin loaded together is the usual cause of duplicate parts and toolbar errors.
