Steps to reproduce:

• Create new ksp181 installation
• Install SSTU, its dependencies, RealPlume, and RealPlume Stock (all most recent versions)

Observe that text on sliders do not adjust when clicked, until the menu is closed and re-opened, and that solid fuel amount does not update.

Thanks for including the logs. Reviewing now, and will let you know what I find out.

One quick (and major) issue that I can see from the logs, that will need to be corrected before I can continue investigations:

• CRP is not installed. This is a required dependency of SSTU, and the mod will not work without it. This is causing the parts to generate errors due to missing resource definitions for propellants, and these errors are cascading to other sections of the code.
  • You can fix this error by installing the version of CommunityResourcePack that was included in the SSTU installation package.

I apologize for the delay.

Unfortunately, installing CRP seems to have made no difference: https://gist.github.com/al2me6/a9382b6a050da84a1f9b84c152b68986.

Apologies, that was my own attempt at transplanting a RealPlume to SRB-A, as I didn't find a RealPlume patch for it in the SSTU folders. I guessed that the lack of a patch might have been the problem, but adding it didn't do anything (well, the plume itself did show up, but the bug persisted).

Here is a log with the patch removed: https://gist.github.com/al2me6/79817e2b6ce4af74fced7600d5bff78c

What is this file you have:
patch-sstu-srb-a-realplume.cfg ?

It is likely causing the issues you are seeing. That is not one of my files, and I cannot provide support while it is potentially causing the very problems to be investigated....

Thanks -- it seems like your log uploads are being truncated however, stopping around like ~9000, long before any of the real juicy bits (hasn't even started ModuleManager patching at that point).

Could you try uploading the full file to dropbox/etc, or somehow checking to make sure it is not truncated?

Specifically, I need to see all of the lines of where it is doing the part-compiling, as well as the lines that are written when in the flight scene and trying to use the particles.

For reference, the SSTU-realplume patch is all located here: https://github.com/shadowmage45/SSTULabs/blob/master/GameData/SSTU/ModIntegration/RealPlume/RealPlumes-ShipCore.cfg

You are not the only one reporting issues with RealPlume, so I have to believe there is some sort of error. However, I'm not seeing any issues on my install, so this might take a bit of time to track down.

You can click "view full file" to see the entire log. Link here: https://gist.githubusercontent.com/al2me6/79817e2b6ce4af74fced7600d5bff78c/raw/96710595969da60c6d6cb48aed7d575ddbfc3e09/KSP-rp-crp-nopatch.log

Edit: ah, yes. This explains why I didn't find the patch in RealPlume-Engines.cfg.

Doh, my bad, I should know that :)

Anyway, I'm finding lots of these in the log:

Which basically means that RealPlume is not finding the plume config that was specified.

Taking a quick look to see if I can reproduce locally; I know there were some issues with a recent version of SmokeScreen that was causing issues like this, but cannot say if that is this problem.

Strangely, I'm not seeing this problem myself, using copies of the latest versions of RealPlume ( https://github.com/KSP-RO/RealPlume/releases/download/v13.1.0/RealPlume_v13.1.0.zip ) and Smokescreen ( https://ksp.sarbian.com/jenkins/job/SmokeScreen/86/artifact/SmokeScreen-2.8.13.0.zip )

(SRB-A, using RealPlume; KSP 1.8.x, with latest versions of TU and SSTU)

The one commonality that I'm seeing between your install and the others reporting issues with RealPlume is the 'RealPlume-Stock' folder.

Could you try removing that folder/mod, and see if the problem persists?

The NREs are only triggered by attempting to change the configuration of the SRB. On my install, the default configurations work fine, and the plume does show (and could be changed by myself).

AFAIK, RealPlume-Stock does not contain patches for SSTU. But I'll verify once I have access to my KSP install.

The NREs are only triggered by attempting to change the configuration of the SRB. On my install, the default configurations work fine, and the plume does show (and could be changed by myself).

Ahh, that would make sense (as to why I didn't see it). I merely took a pod, added SRB, and launched (was checking plumes specifically).

I'll do some further testing with adjustments to the SRB size/length/etc.

Was able to reproduce with just SSTU, RealPlume and dependencies, no RealPlume-stock.
-create vehicle with just a pod and an SSTU SRB
-change core size and note that SolidFuel value does not change and NREs appear in log

EDIT:
-Just as an FYI to maybe save you some time. I did a bunch of messing around with patch order just to see if some thing was getting screwed up, I got to thew point where I entirely nixed the RealPlume patching method and just wrote a :FINAL patch that pulls the stock effects and adds the particles unlocked by smokescreen and still had the issue,
