Both convert.exe and the fbx converter don't need the exe extensions.

On todo list.

To be done.

sometimes it will import models where the toplevel node is -90 rotation and the child is also -90 rotation
Usually, it only happens for a few objects, so it can be manually fixed.

The cause is probably models whose root node got excluded due to having only one child, but maybe applied an extra 90 degree rotation to the parent or the child in the prefab properties.

Result is mesh instance that is empty mesh.

Currently attempting to load this addon and getting a warning of:

Unable to load addon script from path: 'res://addons/unidot/plugin.gd'. This might be due to a code error in that script. Disabling the addon at 'res://addons/unidot/plugin.cfg' to prevent further errors.

I made an fgx2gltf install, and I found a closing parenthesis that might've caused an error, but neither ended up fixed the error and I don't know what else to try. I'm running Godot 4.1.1-stable for Windows. Hope that I gave enough info, please let me know what to try!

When importing a unity package, each prefab that contains multiple meshes has each sub mesh offset. (See photo below)

Additional Information

• I've tried converting multiple unitypackages, the picture comes from a Synty package.
• I'm using this build of FBX2glTF but also tried the official release from June 2023.
• v4.2.stable.mono.official [46dc27791]
• Windows 10

Please let me know if anyone has any ideas or needs more information. I searched quite extensively before posting here, so apologies if this is a resolved issue somewhere.

other files imported fine but prefab importing crashes godot

The README.md still indicates it should be used with 4.0 alpha builds:

Please use the latest Godot 4.0 alpha builds ( master branch of https://github.com/godotengine/godot ) to run this addon.

This issue #14 implies 4.0.3 is not supported

In a future update, update the fbx2gltf notice to mention the switchover to the Godot Engine native importer.

To install, one must download FBX2glTF from https://github.com/revolufire/FBX2glTF/releases/, then rename to FBX2glTF.exe and move it into this addon directory.

the reason for recommending this version is because it is more compatible and is being actively maintained by barcoderdev
https://github.com/barcoderdev/FBX2glTF

Reduce the many steps to create a build.

I am trying to use this tool, but mine isn't converting FBX assets. I placed the exe in addons/unidot/FBX2glTF.exe, but it didn't seem to work. Not sure if there is something I am missing, or if there is something wrong with the version I installed.

Godot: 4.1.1 stable
FBX2glTF: 0.13.1

• Issue 1:
  Need advice on the license if this is for study not commercial, is this fine?

• Issue 2:
  Not sure if limited success is attributed to shaders.
  Request: Even though shaders need manual porting, it would be great if at least these shaders are attached correctly

• Issue 3:
  It seems many of the textures e.g. for the Globe are not attached correctly. This is the first time I encounter this using unidot.

Copying the AnimationLibrary dictionary ("T-Pose") from the imported gltf, applying to rest pose, and copying the skin from the imported gltf will workaround this issue in most cases.

I previously used unidot importer in conjunction with (https://github.com/barcoderdev/unitypackage_godot) ---> their version of FBX2glTF and it worked fantastically for my game project. However, I had to reinstall my project recently and in turn re-install both FBX2glTF and unidot importer (your updated version). But now I'm getting the error below and can't open my project.

*Version of FBX2glTF ( https://github.com/barcoderdev/FBX2glTF/actions/runs/7305203107) I used

Trying to figure out where the issue is. Any help would be much appreciated.

Godot appears to use some of the layers above 20 internally for things such as gizmos or collision shape debug. This leads to certain artifacts in the editor when imported meshes include layers about 20.

The problem is Godot's inspector doesn't show these, so the scene needs to be edited by hand to exclude them

To be done.

I tried to use godot version: unidot_fixes branch of https://github.com/lyuma/godot, Editor show crash GDScript then crash when copy this addon to folder addons.

I am importing the demo scene from the Synty City Zombie Pack. Here is what it looks like when imported into Unity:

and here is what happens when I use unidot to import it into Godot 4.2.2:

each one of these characters is all characters overlaid over each other. I can individually drag them out of these messy piles. They also all seem to be lying on their backs, where Unity imports them standing upright.

Primary Request:

• Batch Import Functionality:
  • Need: Ability to select and sequentially process multiple files for batch conversion.
  • Benefit: This will significantly reduce manual effort and time, especially critical for older hardware systems.

Additional Enhancements:

• Selective Default Import Settings:
  • Function: Option to auto-select all file types for import, including .cs files, with a feature to skip files that cause import issues.
• Persistent Folder Memory:
  • Function: The plugin should remember the last-used folder, simplifying repetitive import tasks.
• Folder View Customization:
  • Preference: Switch from a grid of thumbnails to a list view in the folder selection window, and remember this setting.
• Import Status Indicator:
  • Utility: Display whether a package has been previously imported to avoid duplication.
• Post-Import Workflow Enhancement:
  • Convenience: An option to automatically reopen the file explorer after completing an import, aiding in continuous asset management.

Positive Feedback:

• User Experience: The tool is highly valued for its user-friendly interface and high-quality output. The addition of batch import functionality would further establish this tool as a superior choice in asset importing.

Conclusion:
These enhancements are aimed at improving efficiency and user experience. The primary request for batch processing, along with the additional features, would greatly benefit users dealing with large asset libraries.

Currently when force humanoid is used, the model usually successfully imports as humanoid, but the prefabs referencing the model do not have an Avatar set, or in some cases do not have an Animator at all, so we should add additional logic to handle this case.

The logic should be if force humanoid is on, and there is a skinned mesh referencing a model imported as humanoid (even if forced), the entire skeleton that skinned mesh is in should switch to being a GeneralSkeleton.

This is really useful for importing outfits such that they can be copied and pasted directly from the unpacked prefab (with materials assigned), into the model the outfit is for.

Prefabs aren't loading

Hey,

Thanks for making this it's really a nice initiative.

For fun I'm trying to port a game jam project to Godot but when running the addon at version 8a5956c (and prior versions) some of the assets get replaced by others, I'm not sure exactly why and I was wondering if there was anything I could do to help you fix it? more logs patching etc. One of the object is being used everywhere.

PS: Not sure if that's any interest to you but a friend of mind made a Godot C# => GDScript converter using Roslyn, might serve as base for a Unity => Godot C# => GDscript https://github.com/seb776/CSToGDScript

I've been importing some asset packs from a recent Humble Bundle. Some of the packages import with no issues, however some cause Godot to crash during the import process. The import runs for a few seconds and then Godot closes.
Reopening Godot will cause it to crash again, the only way to get back into the project is to remove the files created for the package in the Assets folder.

I thought this might be from the amount of logs that are generated but i am still having the same issues after removing the print statements in Unidot.

I've been unable to figure out why its happening with specific packages, as im finding it hard to debug the addon as you can not use breakpoints in Godot Editor Addons (afaik)

Link to packages (I can provide if needed):

• https://assetstore.unity.com/packages/3d/props/poly-lite-survival-collection-220452#description
• https://assetstore.unity.com/packages/3d/props/weapons/poly-mega-weapons-kit-215666

Update 16th May, use Godot4.0.3

• Compress textures => fbx model imported without texture
• #3
• file1Animation.fbx
• file2Animation.anim <= not yet

FYI

Ball

The warning disappears once the Ball (non-uniform scale => 1,1,1) is transferred to MeshRenderer

Cube

The transform of Cube, warning disappears once the Cube (non-uniform scale) is transferred to MeshRenderer

First of all thank you for this amazing tool saves me such much time learning Blender animation.

But when I import an animation from Unity all the keyframes are imported correctly but they dont seem to move the skeleton?
I get this error for every keyframe that i think is related to it:

Node not found: "Arms/Root/Left Shoulder/Left Upper Arm" (relative to "/root/@EditorNode@17140/@Panel@13/@VBoxContainer@14/@HSplitContainer@17/@HSplitContainer@25/@HSplitContainer@33/@VBoxContainer@34/@VSplitContainer@36/@VSplitContainer@62/@VBoxContainer@63/@PanelContainer@110/MainScreen/@CanvasItemEditor@9462/@VSplitContainer@9281/@HSplitContainer@9283/@HSplitContainer@9285/@Control@9286/@SubViewportContainer@9287/@SubViewport@9288/M4A1_Model"). scene/animation/animation_mixer.cpp:635 - AnimationMixer: 'M4A1 Equipped Prefab.library/M4A1_SwapFireMode',

Thanks for any help ^-^

I've tried two separate .unitypackage exports, and they both give the same results. The UI shows no assets to import, and the error log shows several errors.

I've tried to debug the problem a bit. There appear to be several problems. The first of which stem from the parsing of the output of tar. tar -zxvf on macOS Ventura (14.0) writes a first line entry for the current-directory indicator ('.'), which 'ExtractedTarFile.new' cannot parse -- therefore the error in the guard code (Invalid member of .unitypackage: [".", ""]). In addition to that, there seems to be another error in fnparts parsing? When each line is parsed via line.trim_prefix("x").strip_edges().split("/"), the results for directory lines appear like [ ".", "1234abcd0000ffff", "" ]. This seems to be breaking the whole script via the failure of the following guard code, which appears to be designed to skip directory-only lines and fix lines that are prepended with the current-directory indicator, but doesn't seem to actually work where there is both leading current-directory indicator and also a trailing empty string, which pushes len(fnparts) over two in the case of directories and over 3 in the case of files.

if len(fnparts) < 2:
	continue
var guid: String = fnparts[0]
var type_part: String = fnparts[1]
if len(fnparts[1]) == 32:
	if len(fnparts) < 3:
		continue
	guid = fnparts[1]
	type_part = fnparts[2]

I'm trying to import some AnimationControllers that are a part of an asset pack that uses FBX for the meshes. From my understanding the animations themselves are a part of the FBX files. All of the other assets in the pack import fine, including the conversion from FBX to GLTF for the meshes. However, when the AnimationControllers import, I receive this error:

When I try to open the generated prefab scenes, the AnimationTree has nodes corresponding to the names of the animations, but attempting to play any results in the "animation not found" message. The corresponding animation library seems to have no animations in it, as well.

It looks like the importer is somehow looking for the asset in its GLTF form, but there is none since it's getting generated by the importer? I can't help much, this is unfortunately outside of my domain. I'm happy to provide files if it helps repro, though.

I see that 4.3 will support FBX natively. Feel free to ignore if this issue will be resolved by that.

Amend the instructions to mention GraphicsMagick is supported.
