That was my guess as well but wanted to make sure

What is KSPIE?

Correct, which is what this fork is doing.

That node is being set by another mod and KSP can't draw the connection to the prerequisite node.

What is the problem? the screen shot looks right.

I haven't installed 1.4.5 yet, so I will give it a shot.

So what is the graphics renderer for non-Windows versions?

So a few things: CTT and ETT cannot be installed at the same time (they will produce several fun conflicts that actually aren't so fun) Part node assignments are also not always foolproof with modded tech trees (an issue I am running in to with ETTR, even on new installs and new games). I know this isn't very helpful, but hopefully it provides some insights

Yes, for original ETT you need to remove CTT

Not yet. It is just a frame while I work on the mod configs. Probus' ETT does work

there will be an option for each layout.

install the mod "Hide Empty Tech Tree Nodes". Also, Strategia doesn't change the TechTree afaik.

Here is the MM patch I wrote to fix this: Patch

If you don't mind waiting for a bit, I can write a MM patch to fix it until @Probus can update the file permanently. The first node is propulsion systems, right?

No way to control if lines go thru nodes (at least not directly), which is annoying to say the least. KSP draws those procedurally. As for the arrows on the propulsion branch, the lineTo and lineFrom parameters need to be flipped on those nodes (right now it is lineFrom = LEFT lineTo = RIGHT, needs to be lineFrom = RIGHT lineTo = LEFT)

You have to jump into text files. There really isn't any other way. (the KSP Tech Tree Editor program doesn't like CTT-style trees because they are not complete trees, only MM patches to move/alter stock nodes + new new nodes).

@blackheart612 it was no trouble at all.

Yea, it is 1.875m for size scale, but if you want the tapered asthetic of the Titan-Gemini rocket (using the stock parts), then it requires using the 2.5m parts to make the Titan (and a mod to get the tapered SM). I kind of wish they (squad) would have made the Gemini-esque capsule 1.5m and then the 1.875m titan parts would work. Oh well, that's why I like BDB Oh, and I have a MM patch to reduce the fuel on the BDB parts so that getting to space is a bit trickier (unfortunately it doesn't affect the fuel loads in my pre-built BDB craft).

I would not try to install this yet, it isn't even in alpha, but yes, this mod will be incompatible with Probus' ETT mod due to having several conflicting node names and more importantly, no longer being dependent on Yonge Tech Tree. Only 3 of the ETTR-specific nodes have icons and very few have descriptions, that is what all the errors are from. As for HETTN, I plan on looking in to how to make the two play nice, but for now it's a bit down the to-do list.

Got localization working (although most of the descriptions are still blank) and started on adding icons. Also created a small cfg file for USI Sounding Rockets to test a few things. Anybody know if there are lists of parts for the stock game and MH expansion (or any other mode)? I can go through the folders manually, but anything I can do to avoid tedium is a plus in my book.

Literally less than 40 days in to a brand new game. Have OPM installed though, so maybe that has something to do with it?

So figured I give this a shot just because, and about 35 days in I get the following message: Error extending trajectory for Laythe. Error trying to fit a smooth polynomial to the trajectory. The approximation error jumped from +2.30344324226492217e-03 m to +8.35706270893752298e+03 m at time +1.57920000000000000e+06 s. The last position is [+2.82771976953634682e+10 m, +5.89455954369199753e+10 m, +3.17994282982390106e+08 m] and the last velocity is [-3.61414693067490953e+03 m s^-1, -1.47464668046310658e+03 m s^-1, +9.66125813160947615e+01 m s^-1]. An apocalypse occurred and two celestials probably collided because your solar system is unstable. (Basically, Vall got thrown out into a Kerbol orbit). I guess the Joolian system is still unstable? Not a big deal, really just want to how to hide the message box so it isn't taking up so much of my screen.

AirplanesPlus for planes, USI Constellation (about 7? different mods) adds all sorts of stuff, ProbesPlus! is another good one, DMagic Orbital Sciences, KW Rocketry, etc BDB is rescaled to stock, the problem is that when rescaling a full-scale rocket to stock scale, you end up with a rocket that is balanced for a 2.5x scaled system. You could either reduce thrust/fuel in the VAB for the BDB parts or write a module manager patch for them (which I have been thinking about doing for myself anyway). Of course, you may also find that stock parts are not balanced well for the stock system (for example, the Saturn V analogs are either really under powered or really over powered depending on the stage, and the Titan-like dual rocket nozzle is too weak to propel a Gemini-like rocket, even ignoring the fact that it should be a 2.5m rocket instead of 1.875m).

The pinwheel layout is definitely my preference for this tree as well. The current layout came from 2 things, 1) a request in the ETT thread for a more traditional layout (some people found the pinwheel confusing) 2) From a practical standpoint, figuring out how the various nodes related to each other (if at all) is far easier in a first pass if I grouped similar techs into the same row (for example, all the SRB stuff is in the same row, all the propeller engines, etc). When the pinwheel returns in this fork, I am hoping to make several small pinwheels centered on each Engineering branch, although I'm not sure if the layout space is large enough to do this.

So I stop cluttering up the thread:
