Those two screenshots were made by @Friznit, so I don't know exactly what's in them, but yes, ReDIRECT is the main one.

v2.1.1 is now out on Spacedock and GitHub. Very small update to fix two silly errors: Changelog: Added missing Launch Plates tech tree node for the Unkerballed Start tree. Fixed typo in Mounting Platform description. Completely forgot to add the new launch plates custom tech node for the Unkerballed Start tree for the release.

@pTrevTrevsI've did test runs with both the Cormorant and SOCK shuttle stacks on the pad, and they worked fine. Make sure no parts of the stack are clipping into the shuttle base, tower and arms. Particularly watch out for the SRB nozzle and skirt, if the SRB is a stock one the collider(s) may not match the visual object and could be clipping the launch base. Realistically, only the nozzle itself should be down in the exhaust hole, the aft skirt should be slightly above the deck. Might have to raise the whole shuttle stack so the nozzles are clear of the base.

Was this in v2.1? Otherwise I have no idea what's going on, as the Soyuz Base works fine for me:

I simplified the elevators in v2.1, now all the elevator towers have just one elevator car or pad, put at a maximum height appropriate for the intended use. This way it moves at the same speed and there isn't any needless duplication of the car/pad meshes. The Large Elevator tower does have two base versions, one with a 70m elevator car and one with a 130m car.

Thanks! The Titan II tower was weird in that the umbilicals were mounted on these short angled (or straight) arms/beams, but the hoses ran perpendicular to the arms at a 90° angle. Why, I don't know The Titan II arm nodes on the tower are placed where the arms should go, and the arms shouldn't need tweaking. Instead move the tower down a small bit if necessary. Most of the footings are just padding to ensure they reach the pad static's top (due to collider issues with the stock launch pad statics) and can be put below the VAB floor.

It shows the colliders in a part, color-coded according to mesh, box, capsule or sphere type. Mostly a dev tool, but also very helpful if you're the type who builds mechanical moving things out of stock parts.

I think that is due to Collide-O-Scope, but it's harmless, just means I saved them with it present. Doesn't affect the craft file. If you want, just save it again and reload.

I should clarify that if you aim the camera at an animated part, then move it. Happened when I tested crew arms and had the camera aimed that them when I retracted them. You might have at aimed at one of the clamp arms.

That happens if you aim the camera at an animated part while it's moving.

Eventually yes, but for now, since those are all BDB rockets, you can use the included craft files as a guide; they are the same as the ones in my screenshots.

No, staging them can only be done in one direction, the default to the left one, as Animated Decouplers can only handle one animation. If you want the arms to swing the other way, it has to be done via action group, as that's a different animation.

OP has been updated. Most of the screenshots and feature descriptions replaced or updated. Most of the new screenshots are mine, as I had to remove the older non-Saturn and Shuttle Zorg ones since they now are outdated, and Zorg has been too busy making stuff for BDB to actually play KSP and take those amazing screenshots.

All the old v2.0 internal part names have been retained by one of the new split off parts, so existing craft files will still load. They however won't look the same, as they may use a size variant that now is a new part. So for example you may get a large launch base where you had a small one. The General Service Towers and Saturn and Shuttle towers have also been furthur converted into separate modular sections, so they will look very broken, but still load; just need to be rebuilt. KSP no longer updates attach nodes in existing craft files if the nodes have been changed in the parts themselves, so everything will still be attached to them.

VERSION 2.1.0 RELEASED! NOW ON SPACEDOCK AND GITHUB CHANGELOG: NEW NEW NEW NEW NEW All parts are now hidden from the stock Structural category. Use the custom CCK category tab or the stock custom category (which has subcategories) to find the parts. Delete the Hide_Parts.cfg in the Category folder if you want the parts back in the Structural tab. The former multi-size merged parts have been split off into separate parts, but the older internal part name is still used for one the new parts. Existing v2.0 craft files will still load, but most likely won't look the same, and will need to be rebuilt. NEW: Historical launch stands for the Bluedog Design Bureau Vanguard, Redstone/Jupiter/Juno, Thor/Delta, Atlas and Titan II rockets, but can be used with other rockets of the same diameters. NEW: Historical service towers for the new historical launch stands. The Titan II tower comes in single-piece and modular section versions. NEW: Jupiter-style Petal Cover for the Redstone Launch Stand. NEW: Mercury-Atlas Crew Elevator, with separate Mercury-Atlas Crew Walkway. Walkway has switchable mounts for use with the smaller crew elevators. NEW: Atlas Mini Modular Tower, which serves as the historical Atlas tower.

REVISED REVISED REVISED REVISED REVISED: General Launch Stand has been split into separate Round and Rectangle versions, and both completely remade. Redstone-style service pole removed from Round version (now in the Redstone Launch Stand), but still available as a separate part. REVISED: Flat and General Launch Bases have been split into separate sizes, with added detail and hole options, and new ladders. Ladders and railings have separate switchable colors. REVISED: General Service Towers have been split into separate size versions, and each split into separate modular section parts: stackable core, multi-height section (except for the Extra-Large Tower) and top section with optional mast(s).

REVISED: Mass values for the Saturn and Shuttle tower sections have been reduced to tiny amounts. REVISED: The Freestanding versions of the Saturn and Shuttle Launch Bases (in the Extras folder of the download) now have switchable masses: 1 ton for transport, 2000 tons for on the launch pad. REVISED: Soyuz Launch Base parts now have a third blue color option, based on the ESA Soyuz pad colors. REVISED: Soyuz Large Fuel Arm, Small Fuel Arm and Gantry. More height options, straight-sided extension for the Small Arm and switchable-adjustable platform stack for the Gantry. GENERAL GENERAL GENERAL Extensive use of B9PartSwitch transform move and rotate, node move and UI Group features for smaller part sizes and easier to understand Part Action Windows. All launch clamp bases and stands can now have the staging disabled when a milkstool or launch rail or other part is attached to them. Various part title and description changes; part cost is now 1 for everything. Removed simple rescale patch from Extras. Realism Overhaul now directly supports Modular Launch Pads, ask the RO devs for additional support/help if needed, it is their responsibility. Remade all craft files for v2.1. Subassemblies removed, there are now four Example MLP craft files (with a stock rocket for demo purposes), along with bare versions of the Saturn and Shuttle launchers. The OP will be partially updated, and the new screenshots will come later (it'll take some work)

Craft files have been rebuilt to v2.1 specs. They cover a range of BDB rockets, a few from Tundra, the Tantares Soyuz, and the SOCK and Cormorant shuttle stacks. All were made in KSP 1.8.1 I also removed the old Subassemblies folder, it's been replaced with four MLP v2.1 Example files (using stock part rockets), plus bare versions of the Saturn and Shuttle launcher assemblies. Caight and fixed a silly bug in the Small Crew Arm - Small Mount. Retitled a lot of the Saturn parts to give a better order in the part window. I also added an in-flight mass switcher to the freestanding Saturn and Shuttle launch bases in the Extras. Now their initial mass is 1t so they can be transported easily by a wheeled or tracked vehicle, then switched to 2000t once on the launch pad. Just have to assemble the new screenshots for the OP, write the changelog and update the OP...and it's release time!

Thanks! It's become my passion now, so lots more to come. I've been (slowly) rebuilding/finalizing the v2.1 craft files, as well as taking basic screenshots and making launch demo clips, starting with BDB. Along the way I've been making small fixes and putting them on AlphaDev, despite what I said. Namely, I gave the Gemini Crew Elevator just one elevator max height like the other elevators, since I forgot about it. I think I will get the craft files assembled, then do the official release, saving the updated Ignition Sequence Start video for later. Expect the release to happen this weekend.

This is Halloween, this is Halloween, Jebkins scream in the dead of night!

And with that, plus some .cfg revisions for the Saturn and Shuttle parts, v2.1 dev work has ended! Final update to AlphaDev has been done, any furthur changes/fixes will be done in the offical release. Now to make up new craft files and do the assembly for the release, as well a new trailer video and assembly guides (those may have to wait a bit).

Yee hah!

Running into a problem with trying to use B9PS to rotate the launch clamp bases. What I had thought was working with the Atlas stand was actually a result of the foot pads and column beams being in a symmetrical square pattern, so it only looked like it was working. When I tried a non-symmetrical pattern, it was clear that the launch clamp transforms were not rotating with the main stand mesh. They can be rotated just fine in Unity, but once in KSP, ModuleLaunchClamp locks down all the related transforms, and not even B9PS can affect them. I got around that problem with the Atlas stand by deleting the troublesome meshes, which was ok since they were irrelevant anyway. For the Saturn and Shuttle bases, I tried rotating the actual meshes for the columns and foot pads with B9PS and not the parent transforms used by ModuleLaunchClamp. They did rotate that way, but not with the launch base mesh, they were very out of sync. So I'm going to provide a separate alternate rotated version, done in Unity, with the columns and such positioned properly, Forget all that, I was doing it wrong. With some help, I got B9PS to rotate the base properly! No need for alternare versions. https://gfycat.com/knobbyuncommonallensbigearedbat

Revised the Soyuz base blue color, making it more like the actual light sky-blue shade, as I had unintentionally darkened it to something like the Delta II blue.

Added a yellow color option to the general and launch stand umbilicals and general swings arms. The Vanguard tower was reworked to have the transform moving method. Functionally no different, but now the visual height matches the engineer report's height, and there's node moving for the bottom attach node.

Just put the final part of the v2.1 Soyuz Base update on the AlphaDev branch. The Small Fuel Arm had the height variants done differently. I replaced all the duplicate arm meshes of various lengths with the new separate modular section method. The base arm core height is still the tapered style, but the longer variants now use a straight-sided extension so they would stack properly. The modular section method allowed the .mu file sizes for the small, large and gantry arms to be slashed in size, with reductions of over 60% or more. The Gantry was greatly reworked . There are now more height variants, and only one elevator max height like the other crew elevators. The gantry platforms now have three "stack" height options, and the whole stack can now be move downward up to 2.4m with a new deploy limit slider. Of course, B9PS UI groups have been added as well. I also added a separate version of the Soyuz crew elevator, so if only the elevator portion is desired, it can be used without all the gantry arm stuff. Attached to the usual tower/accessory nodes. And the final thing....the blue color option has now been added! Thanks for reminding me of that; I had planned to do that but it slipped my mind. It will be part of the final v2.1 updates.

Thank you for this! I was able to make all the launch bases, plates and stands in the upcoming v2.1 of Modular Launch Pads able to have the clamp staging be disabled. And....I added a General Mounting Platform to v2.1. It's an alternate version of the Mini Frame Flat Launch Base with a solid deck, side attach nodes, toggleable railing and 25m extensions below the foot pads for use on uneven terrain. It's not in my MLP custom categories (stock and CCK), but a single part in the Structural category.
