It's node_stack_top, and the y-axis value (middle one of the first 3 values).

The attach node on the base and the extra one for the BDB S-IC are not aligned in any way, just placed at random spots. Just have to offsrt them into proper positions. They'll get aligned in the remake, but that's for the future.

Ah, I forgot to delete the old version on the GitHub. Just did so now.

I also updated the separate versions of the Centaur arms using the revised models. The retractor (that tripod-like thing behind the arms) can be moved downward with the slider or toggled on/off. They're also on the GitHub now.

Now it's done, demo made. Parts will be on the GitHub master branch.

Ended up modifying Arm 1 (the angled upper one) instead. Looking at one of the good images I have more closely, I realized that I could extend the umbilicals by adding a short fixed section, long enough to align with the Arm 2 umbilicals without having to move either arm backwards. I also tweaked the two inside umbilicals of Arm 2, shortening them by small bit. Now the arms match the old ones:

I have to tweak the position of Arm 2 (the flat, lower one) and possibly the umbilicals as well to get it to align with Arm 1 in the default position. The umbilicals for the arms are set up only in Unity, where having the origins (which are the points of rotation) at 0,0,0 makes animating them very easy, but which means I can't see them in Wings3D, so I ended up putting both arms at the same maximum forward position. Oops

At last.....

Got the tower part into KSP. Default color is the mostly gray with mixed red upper parts as seen with the Pioneer 10 launch; alternate colors include all medium gray and all red, plus the usual others. Has 4 taller height variants; the default height will align with the BDB Atlas SLV3-Centaur D.

All dressed up, ready for Unity The whole arm frame has been redone, it's now more of a plate with more concealed extension for height adjustment. I also realized I had the arms on the wrong side of the tower, so they've been moved. Both arms will have horizontal X-axis adjustment, and the big Arm 1 will still have vertical adjustment with a modifief mount.

WIP Wings3D screenshot of what I've been working on, the Atlas-SLV-Centaur (or just Atlas-Centaur) tower. Still a lot more details to be added (like a ton of pipes), but the worst is over (the arms will still be separate).

New Atlas in BDB and new Atlas-Agena Service Tower in Modular Launch Pads:

After some more tweaks to the tower and arm, the Atlas-Agena Service Tower is done. Added 3 height variants: a shorter one and two taller ones. Also, turns out the aem has to be rotated a slight bit in order to fit the tower on the LC-14 static from Tundra's Space Center; how much depends on how close to IRL you want it. All the images of the Atlas-Agena tower I looked at were angled shots, but it seems the tower and Atlas were lined up with each other. With the arm mounted on a cut-out corner of the tower, I had to make guesses as to how that alignment was done. Anyway, here is a little demo; the tower and revised arm are now on the GitHub master branch. Oh, the exisiting Atlas Mini Modular Tower was renamed to Mini Modular Service Tower Type 4. Haven't yet changed the part iteself, may just leave it as is.

Actually, I am going to make a dedicated Atlas-Centaur tower. Two of them, in fact, as I will do the Atlas G/I/II version and arms as well. I might be able to combine the the two towers in one part depending on how much different they are. The original is shorter than the later one, and if it is just that with some detail changes then it is doable, but if the two have size and other structural differences then they will be separate.

And it's in the game, after some revising and minus the height variants (which won't be a lot): I had to modify the Agena Umbilical Arm. One, I removed the taller umbilical section variant, as the top would clip into the tower when retracted. Two, I think the actual umbilicals were angled, not straight out, as the latter case would put the tower way too far to the side of the Atlas itself. Angling them puts the tower in a position better matching the pictures. The collider on the tower does not go all the way to the bottom, leaving some leeway for clipping the tower into the pad static if desired. This is also the first use of fake "stairs" in a tower.

SLC-4W is more asscociated with the Titan II variants launched there, and that isn't planned any time soo. Raidernick has the tower in his US Rockets mod. This isn't BDB, I only do the common type, and just focusing on the tower as used with the Ranger launches, since that's what I have the best images for.

The Agena Tower is coming along nicely. WIP Wings3D screenshots, still need to add extra details (railings, pipes, etc.)

RO and RP-1 use Kerbalism, a customized version of which is included with RO. Do not add any other LS mod.

It is a stock cheat function. With KSP v1.1, it was renamed to Object Thrower (Mu hated the name "Whack A Kerbal" ).

Next up is a proper Atlas-Agena tower, something I wasn't in the mood for when I first did the Atlas stand parts. Now I am It'll be a one-piece tower with adjustable height, namely the lower portion. It will still be at at least the actual height, so no shorty versions that I keep seeing. The portion that holds the arm has a chopped-off corner with some cutouts on top where the arm fits into when retracted.

Added a modular version of the Delta 4 tower. It's just two parts, a stackable multi-height core section and the half-height top section. The top section has the side detail and front truss structure, both of which aree switchable on-off separately. Both parts have switchable side panels in the three styles or off. Also made the side panels in the one-piece Delta 4 tower switchable off-on. All are on the Github master now.

Revised the clamp version of the shuttle launcher base (made the SOCK variant SRB holes wider, to match that of the SLC-6 launch mount), and converted the free-standing version to that of the new clamp version. All are on the GitHub master branch.

Polar once around launch, anyone?

The SLC-6 parts are now on the GitHub master branch. I also put the shuttle craft file shown in the pics and video on the GitHub, in the Craft Files folder; it's not in any sub-folder. Requires SOCK, ORANGES, Photon Corp, and possibly reDIRECT. Do not actually use this shuttle assembly beyond merely clearing the tower as the SRBs are not attached to the ET with decouplers. This file won't be in the v2.8 release, but if someone makes a fully-functional shuttle stack with the SLC-6 tower, I'll include that.

Made a short demo/guide video for it. I might do a full assembly guide later, but in this one I show off each part and its PAW settings so they can be replicated.
