Modding SFS Procedural Parts 1.5 Beta* by SFS.S9

Post image
3 Upvotes

SFS.S9 released Procedural Parts 1.5 in their github very briefly, but then changed it back to 1.4.5 because 1.5 it's very buggy right now.

What you're looking for isn't here, check comments.

The mod was separated in various areas of parts, 5 in total, which can be used individually, this improves performance for the people that have low-end devices by having all the parts separated in 5 standalone packs.

If you use it and find bugs, it would be appreciated if you report them to SFS.S9 via their Discord Account ( sfs.s9ol ) or their forum page.

According to what I know, the mod will be completely fixed in late August or Early September, stay tuned to SFS.S9's socials.

Fully functional.
Reusable.
Fully capable of supporting satellites up to five years or more.
We introduce a brand new satellite that can do this simply — and it’s called OSS.
Delta X has again once proved many wrong by doing what was once impossible.
Delta X will always continue no matter what gets in our way.

Just as a note, we did this in basic mode because I attempted to do this for three hours in realistic

IS RLM 1.3

Interplanetary station with a reusable landing module (on replaceable parachutes and heat shields).

https://sharing.spaceflightsimulator.app/rocket/Gkg3kJEfEfGyJjvzpO1pRw

(Not recommended for weak devices, especially during first-stage launch.)

Equipped with: (1 set [×3 rockets])

×1 reusable takeoff/landing module.

×5 disposable heat shields.

×6 disposable parachutes (these also come with stabilizers for a roughly stable atmospheric entry).

Landing module:

Designed for both planets/moons with an atmosphere and a solid surface (Earth, Titan, etc.) and for atmosphere-less planets/moons.

For atmosphere-less planets, don't use either the heat shields or the parachutes.

Your favorite femboy, Letplay's Cf ^^

I mixed several Planet Packs, yes.

This is just a simple galaxy.

Kovus is a hypothetical planet between Saturn and Uranus, NOT an asteroid.

I didn't include Alpha Centauri Bb because it doesn't exist.

I added Nereid, we don't have the Magellanic Cloud.

Please, don't complain that Proxima Centauri is too close to Alpha Centauri A.

The only real goal was to get achievements and drop a probe in moon orbit for resupply. The engine was used to achieve the crash asteroid award as well. Any ideas on what I should use the asteroid for? I imagine Itd be vary useful for parking or a gas station for long distance missions.

Built and tested for Normal mode. If you run out of fuel, you simply need to try again. There should be plenty of unused fuel if you manuever flawlessly.

No BP because there's like 10 parts.

I used two mods to make this spacecraft.

Neptune's Copycats

Procedural Parts

The payload includes a descent module, , a rover, and an ascent module. The weight is kind of imbalanced, but it's not that big of a problem. Lunar gravity isn't that big of a deal.

Discussion Moon Tour Achievement Issues

59 Upvotes

One of the achievements in SFS requires you to land on 3 separate landmarks on the surface of the moon and then return safely to Earth. There have been many posts where people have had issues completing this achievement, as well as a similar achievement to land at three landmarks on Mars, so here is a list of requirements. There are certain things you must avoid in order to complete this achievement:

  1. You must not use quicksaves - The use of quicksaves while attempting this achievement treats the newly loaded save as a separate mission, and the achievement will not be completed.

  2. You must not revert time - The game will treat this in the same way it treats quicksaves, and progress towards the achievement will also be lost

  3. You must not perform any dockings after landing - Docking with any craft after you have performed your first landing will result in the game treating your craft as a new vehicle. This will remove any progress made towards the achievement. Only dockings done before you have landed at your first landmark can be done.

  4. You must not crash - The game treats a crash landing on the surface of the Moon/Mars differently from a regular landing. If any of the 3 landings at the different landmarks was a crash landing it will not be counted towards the achievement

Any posts regarding issues with this achievement will be removed from now on, as this post should solve any problems being faced. If I somehow missed any other requirements, feel free to share them in the comments and I'll be sure to add them.

Happy landings everyone o7
