Part of the NecroBones suite of mods, that work nicely together:

Modular Rocket Systems is a parts pack for KSP, with the following design goals:

  • Fill in some of the gaps in the selection of stock parts. For example, size-3 and size-0 SAS modules, and size-3 monopropellant tanks.

  • Preserve the stock balance. All parts have their costs, masses, and capacities chosen based on stock analogs.

  • Provide some additional cosmetic choices. Examples include the 2.5m fuel tanks, and various nose cones. They have direct analogs in the stock line-up, and share the same stats, but give you additional aesthetic options.

  • Maintain a stock-like appearance and seamlessly fit into the game, while following its own artistic style. This one is trickier, but by taking cues from the stock-parts, it's possible to make something new, that also fits with the game's existing aesthetic.

  • Be friendly to your CPU/GPU. Very importantly, these parts follow most of the stock-part rules for how polygons are used, and collision meshes are configured. They shouldn't reduce your framerate any more than the stock parts do.

Note 1: This is my first mod / parts release. All feedback is welcome!

Note 2: I would love to see screenshots of these parts in action! Please feel free to share them on our forum thread.

All of the models and textures were made 100% from scratch, using Blender, Photoshop, and Unity. The only exception is the "mini orange tank" which borrowed a scaled-down sample of the orange pattern from the stock Jumbo Orange tank.

"Modular Rocket Systems" is also the in-game manufacturer of these parts, and they will appear as an agency that can provide contracts for career mode (assuming I've set it up right - untested), and have a flag available for use as well.


Installation Instructions:

  1. If upgrading from a previous copy, it's recommended to delete the old "ModRocketSys" folder first.

  2. Backup your "saves" folder! While not required for installing mods, it's a good idea anyway. If any parts you have already used (including stock parts) fail to load, you'll have ships getting deleted!

  3. Download and open the ZIP file.

  4. Copy the "ModRocketSys" folder into your "GameData" folder.

  5. If upgrading, check your designs in the VAB/SPH. If attachment nodes have changed, you may need to reposition parts. Stock-alike parts that fill in gaps in the stock selection, and offer additional NASA-like cosmetic options.
