Overkill Plumes

Switchable configurations for some Kerbal Space Program engines that aim to add stylistic and somewhat hard-sci-fi-accurate exhaust plumes. Mainly just ModuleManager patches and homemade Waterfall templates.

Dependencies

These mods are required for Overkill Plumes to run properly. You'll need to install each one (and their own dependencies) before installing Overkill in order for it to work.

• Waterfall
  • The Waterfall effects framework is used to render custom engine plumes.
• ModuleManager
  • Effects are applied to parts using ModuleManager patches.
• B9PartSwitch
  • In-game plume switches are created using B9PartSwitch modules.

Compatibilities

These mods are not required for Overkill to run, but are currently supported through patches. Effectively, these are mods whose engines can get Overkill plumes.

• Far Future Technologies

  • X-2 'Heinlein' Nuclear Salt Water Rocket Engine
  • X-42 'Niven' Nuclear Salt Water Rocket Engine
  • A-834M 'Frisbee' Antimatter Torch Engine (Compatible with Interstellar Plumes)

• Stock Waterfall Effects

  • LV-N 'Nerv' Atomic Rocket Motor (Compatible with Restock)
  • Kerbodyne KR-2L+ 'Rhino' Liquid Fuel Engine (Compatible with Restock)

Every supported engine gets a plume switcher in their right-click menus to return effects to their original looks. Most switchers also offer a faux-antimatter option for that additional aesthetic kick.

Installation

via CKAN

A CKAN listing is actively being worked on. Download via the SpaceDock link below for the latest actual release.

via SpaceDock/GitHub

Download the latest ZIP from SpaceDock (or the GitHub repo's Releases page) and simply extract the folder directly into your KSP installation's GameData folder using File Explorer's "Extract all" option. You may also extract the folder manually and place ONLY the OverkillPlumes folder inside GameData.

When done correctly, the path to the mod should look like this:

KerbalSpaceProgram/
└── GameData/
    ├── OverkillPlumes/
    │   ├── Flags/
    │   ├── FX/
    │   ├── Patches/
    │   └── ...
    ├── Squad/
    ├── YourOtherMods/
    └── ...

Known Issues

• Overkill plumes don't react to atmosphere depth and only ever display vacuum-accurate plumes. This is intentional for the first few releases, and atmosphere-accurate plumes will be added to all supported engines over the span of future updates.
• KerbalAtomics conflicts with Overkill Plumes. Installing it alongside Restock and SWE causes the Nerv's LF mode to lose its sound and visible plume. This is a conflict between KerbalAtomics' and Restock's own patches, and is outside of Overkill's scope to fix.
