Gimp Normal map affects COMP green channel? |

I am creating a livery for an Aeroplane Heaven model for MSFS. I understand PBR, and I am able to get the look I want using the amazing tools in Gimp which is my main program for liveries.
I wanted to redo the lines and rivets on this particular model as they were quite messy, my repaint is depicting the restored aircraft so I wanted a better organized NORMAL. I redrew the entire lines and rivet network for the model using layers in Gimp 2.10. I started to use NORMAL Map feature ( Filters/Generic/Norm) and I got great results, but one thing has me baffled. It seems the new NORM texture is affecting the "shine" of the model in game (typically controlled by the COMP's Green channel). I don't understand how that is possible when I am working on the NORM texture exclusively.
With the export, I made sure the Alpha channel was turned off, 16bit NORMAL, Y not flipped (the result of flipping the Y was not correct). When applied, the model lines, rivets, hatches, all look fantastic, except now the sheen on the model is extreme. Reverting back to the messy default NORMAL, sheen is correct.
Could anyone please help to explain how the NORMAL map generated by Gimp results in an over-polished sheen on the model in game?
Workflow and results:
Multi-Layered Master
Collapsed_Layers_No Alpha
Converted to NORM Alpha Off
Export to DDS settings
Shine difference shine difference
Shine Difference Underside shine difference
Thanks for reading, any advice is appreciated.

How to Recover File after a Crash? |

I'm using:
Windows 10
GIMP 2.10.34
I was following a tutorial and Gimp crashed.
I hadn't saved. Yeah, I know, I know...
Anyway, is there a temp folder where I can retrieve the unsaved file?
I found two temp folders connected to Gimp but they were both empty.
Thank you,
AngelH.

Updating GIMP in Linux |

Greetings,
New forum member here.
I've been using GIMP, mostly on Windows and at work, for a number of years and am a faithful disciple.
My profession life ended on May 5th with my retirement and I'm now officially a "free man" and old fart....
We are in the process of building a new retirement home, so my focus of late is trying new things computer wise, with one of those things being Linux.
After some looking around, Elementary OS was chosen (don't ask me why, I couldn't tell you) and It's been an interesting experience for this old man to wrap his head around after so many years of Windows-dom. EOS is an Ubuntu variant BTW.
It took some doing, but I've gotten EOS where I wanted. One of the interesting things I came across was the myriad of ways to install applications.
EOS is fond of flatpaks so initially I installed flatpak applications. Some of the other applications were snap packages, some where apt packages and a couple were just executables.
What I found was this unholy mixture of install types lead to some very interesting file access issues. Some flatpaks would see folders while the snap packages wouldn't, etc, etc, etc.
After a bit of to-ing and fro-ing, I decided to throw flatpaks and snap packages to the curb and just install stuff via good old apt install.
This has solved my file access issues, but I'm finding now that GIMP is stuck on v2.10.30 vs the latest v2.10.34.
Is there any way to update my install without going to a flatpak?
Thank you!
chris
LOL,
I should have read a little further...

fading text layer |

Hi, I am new to this forum so if I my question is in the wrong section, well, sorry I guess!
I have a pdf form to fill like 500 times and I thought using a gimp python plugin is the way to do it. I have developed the said plugin and I can successfully fill the form except that the text layers I am adding are too sharp. Before I save the file manually, I usually use the blur tool to make the text look like it was filled with a pen. I have tried to do this in the plugin but I can't get i right. I am using the gimp.convolve() function. I guess my problem is obtaining the stroke points of the text layer. Can somebody please help me. Thanks.
