Hi
I am trying to make a layer mask from an image with a busy background. I am using the method where I change the method from RGB to indexed. Everything seems to work fine, in removing the colours, but when I change the image back to RGB, it appears all pixelated, hence after I complete the process to the point where the final image appears on a transparent background, it is STILL pixelated. 

I tested this by changing the image from RGB to indexed on a setting of 16, and when I changed it back again, it never returned to the RGB mode>

Could you please tell me what I am doing wrong. 

The YouTube clip I used to refer to was one that I save a long time ago, and I think the author was "Rich", but I cannot find the tutorial any more.

I've noticed that on some images, specific parts of the image will occasionally become black and grainy when the Hue-Saturation feature is used. Is there any fix for this? Does anyone know what causes it? I've tested a little bit, and it seems that the black artifacts always appear, no matter what I do with the Hue-Saturation feature.

In the first attached image, I have not used Hue-Saturation yet. Some areas of the coral are naturally in shadow, but still have a color that makes sense and looks pretty good. In the second attached image, I tried to use Hue-Saturation to remove some green tint from the image. It worked, but left some areas of the coral that were previously in shadow with a black, grainy look.

My toolbar has gotten messed up somewhere, it doesn't list the color / font name / etc when I click on the text tool. My skill level is pretty beginner, I can do simple things like this but when it breaks, yeah... >.< Can anyone help me figure this out? Thanks. Oh! Almost forgot, this is Windows 10 x64 ver: 21h1 and Gimp 2.10.24 Rev 3.

(Not sure if this is the right place for this) but I’ve been seeing this videos of people that use an app (not sure which ones they use) and they take one image and use an outline of another to move and warp one photo to fit the other. It’s almost like the smudge tool except nothings smeared or blurred it’s only warped, I’m not sure how I could replicate this with gimp but I was wondering if anybody knew any tools/settings that could do this (I’ve been looking for a while) any infos appreciated

Sup   . First post yet. I'm a newcomer, and I need help for a specific task: make a race car livery for a game.
I'm not english native, so expect some mispells and a software in French.

So here's the deal: I extracted a net from the game files:
 
This net contains 2 layers (calques):
-Texture

-UV

UV layer is the outline of the model and Texture, welp, texture. What i'm  trying to do here is to use the UV layer to paint the car, but I don't want those grey outlines on the model. Here is what it looks like:

 So I guess I need to add a new layer (Livery) and try to match it with UV, then erase the UV layer after I painted the whole thing.
Any ideas?

Hi, I have plugins at

C:\Program Files\GIMP 2\share\gimp\2.0\plug-ins

But none of them appears inside GIMP in Windows 10. I copied the plugins from Ubuntu What to do now ?

Hi, I need to adjust the green patch inside the white stroke. But not sure how to select all those green fills at the same time. Any help will be great.

I figured out how to change the default unit of measurment from px to cm for a new image, but how do I do the same for an image I've copied from the net and pasted into gimp as new image (Ctrl, Shft + V)? When I go to resize for this, it's still in px?

Hello everyone, some time ago I made an image with an audio spectrum effect, and my problem is that I can't remember what kind of filter I used. I want to know if you can help me to achieve the same effect, what I remember when I make the image was that the filter I used can fragment the image in a grid and the distance between every "cube", as a result of the grid, was configurable so I modify some values to get the effect I desire. To clarify, I just make some big lines with green color in the layer that I applied the audio spectrum effect. Here is the image I made:
