System information

Issue description

When importing new files like (png,jpeg,ogg..). The engine doesnt make an "example".import file .When i started the project i did not have this issue .I tried to fix it by opening the project with other versions of godot 4 but it did not work. (godot 3.5 didnt have this issue)

Steps to reproduce

• Chose a file of your choice (PNG,JPEG,OGG....)
• Put it in the godot project file
• The file showes up with a red X in the icon and can not be used

Minimal reproduction project

import bug.zip

Godot 4.8 beta, are you sure? Version 4.0 is still beta.

Related to #69369. It's possible that removing the .godot/ folder within the project folder while the editor is closed resolves the issue.

@AdamKokrito Please upload a minimal reproduction project to make this easier to troubleshoot.

Godot 4.8 beta, are you sure? Version 4.0 is still beta.

OP is referring to 4.0.beta8.

Done
import bug.zip
I found out that one folder was the issue messing up the whole project

@Calinou I am also experiencing this bug on macOS on 4b10. Deleting the .godot/ folder has not helped unfortunately. :(

[rcjsuen]

I reopened my project with 4b8 and imported some files then reopened the project in 4b10. From then on I was able to reuse my project in 4b10 in addition to importing new files in 4b10 so I am now unblocked. :)

I might be experiencing a similar bug in Godot 4.0 beta 11. In my Windows 11 machine (where I usually work), everything runs smooth and is imported correctly. In my Linux Mint 21.1 machine Godot spits out errors saying that the .png file is corrupt.

In my case, I'm ignoring all .import files and .godot folder. I also have LFS set for the .png files but that seems to be working fine on my Windows machine (I just recloned the project to be sure). Seems to be a Linux-specific thing.

Any other information you think I can provide please ask away

EDIT: Please disregard this. I just noticed that LFS wasn't correctly configured on the linux machine. This is embarassing :D

I found this issue with the latest 4.0.beta11.
The issue started happening after I downloaded a .gltf model (https://sketchfab.com/3d-models/gun-of-leila-from-d-the-vampire-hunter-blood-l-3RXKSlKHlIhV8Cjs1DqRq3mQheN) and placing it in my project. (I tried importing the same model into an empty new project and I couldn't reproduce the .png import bug)
It failed to load its images, and after that, everything else failed as well.

No matter what new png files I want to import they all failed. The images that were imported already when I downloaded the template worked, but after removing the .godot directory they also failed.

The error messages:

  drivers/png/png_driver_common.cpp:56 - Not a PNG file
  drivers/png/png_driver_common.cpp:69 - Condition "!success" is true. Returning: ERR_FILE_CORRUPT
  core/io/image_loader.cpp:101 - Error loading image: res://Level/Materials/._T_Grid.png
  editor/editor_file_system.cpp:1939 - Error importing 'res://Level/Materials/._T_Grid.png'.
  editor/editor_file_system.cpp:2163 - Condition "!importer.is_valid()" is true. Continuing.
  editor/editor_file_system.cpp:2163 - Condition "!importer.is_valid()" is true. Continuing.
  editor/editor_file_system.cpp:2163 - Condition "!importer.is_valid()" is true. Continuing.
  editor/editor_file_system.cpp:2163 - Condition "!importer.is_valid()" is true. Continuing.

I'm running Windows 10. This is the project with the issues:
FPSCharaterController-main.zip

EDIT: Tried with beta 12 and same happens. Tried removing the .godot folder but no luck.
EDIT 2: Trying self contained mode didn't fix the issue.
EDIT 3: Tried removing the Godot cache files from /%APPDATA%/Godot but no luck either

$ file ./Level/Materials/._T_Grid.png
./Level/Materials/._T_Grid.png: AppleDouble encoded Macintosh file

That's indeed not a PNG.

Interestingly though, for me on Linux the file is ignored and not visible in the FileSystem dock, so I have no errors.

No clue what the _T_Grid is, when looking up the model I see something else,

leila_gun_d.tga 1024x1024 png 1MB Source archive

Either the texture file is named "leila_gun_d.tga.png" or Sketchfab website is mistakenly recognizing tga as png?

I'm also experiencing this issue. I am unable to import files via two importer addons (.vox and .sfxr files) and also TTF font files, which should work without addons. All files imported before updating from Godot 3.5 to Godot 4.0 beta 10 work fine. In 4.0, new files show red X icons and the importer panel shows the message seen in Coppolaemilio's screenshot.

I've tried importing new files with Godot 4.0 beta 8, 10, 11 and 12 with the same results.

The errors that shows in the console when I try to add new files are:

  editor/editor_file_system.cpp:1904 - BUG: File queued for import, but can't be imported, importer for type '' not found.
  editor/editor_file_system.cpp:1905 - Method/function failed.
  editor/editor_file_system.cpp:2163 - Condition "!importer.is_valid()" is true. Continuing.

Thankfully, PNG files are still importing fine.
