QtMeshEditor – 3D asset workflow tool (GUI + CLI + CI/CD)

Hi everyone,

I originally created QtMeshEditor as a small helper tool to make working with Ogre meshes a bit easier. Over time, the project has evolved quite a bit, so I wanted to update the original post with its current state.

QtMeshEditor is now a 3D asset workflow tool designed to complement Ogre3D pipelines and simplify common tasks that usually require multiple tools.

What it does

QtMeshEditor provides a unified workflow to:

• Edit meshes and materials visually (GUI)

• Automate operations through CLI

• Convert assets across multiple formats (via Assimp)

• Merge and preview animations

• Integrate asset checks into CI/CD pipelines

The goal is to make asset handling more predictable, easier to automate, and faster to iterate on, especially when working with multiple formats and tools.

Core features

• Mesh transform tools (translate, scale, rotate)

• Real-time material editing and preview

• Import from multiple 3D formats (Assimp)

• Export to Ogre mesh (including older versions)

• Animation preview and renaming

• Primitive creation (via ogre-procedural)

Recent additions

More recently, the project expanded beyond a GUI editor:

• CLI for scripting and automation

• GitHub Actions integration

• CI/CD workflows for asset validation

• QtMesh Cloud (scan history and live badges)

This allows a more pipeline-oriented workflow for 3D assets, similar to how code is handled in modern development setups.

Example usage

Code: Select all

qtmesh scan ./assets -fail-on error
qtmesh fix character.fbx -all -o character_fixed.fbx
qtmesh convert character_fixed.fbx -o character.glb2

If anyone is using Ogre in production or has custom asset pipelines, I’d be very interested to hear how you handle validation and conversion today.

Feedback is very welcome

Very cool application.
Will you open source it too ?
If not it's IMO useless (unless you want to fix all bugs yourself and release it with every Ogre version).
There is some black blinking overlay after I maximized it. I would really use some shortcuts like Ctrl-O - Open, Ctrl-E - Export, and so. Also some edit to just set scale eg. Alt-S then input 0.1 and after enter it scales uniformly by 0.1.
Btw. Is MeshMagick source somewhere to compile it with 1.8 ?

[fernandot]

I'm not thinking of open source now, maybe when in the future i'll release the code
Nice idea, I'll try to add some shortcuts and correct this bug on the next versions...
The MeshMagick code is here: https://ogreaddons.svn.sourceforge.net/ ... eshmagick/

I add an OBJ importer, now u can use this application to convert OBJ to MESH

[gdalex]

This is a very nice job !
Do you handle meshes with multiple materials ?

[Brocan]

Nice!

[robel]

nice job
i hope that i will see the code as soon , because i work too with qt+ogre and i want to see ideas

[fernandot]

ty all for the answers, i'm glad to know that u like it, i'll try to spend more time updating this project...

As you are asking for the code, i've change the repository to allow public reading, i'll be happy if my codes helps someone... there are some workarounds, sorry about that
https://xp-dev.com/svn/QtMeshEditor

gdalex: it is handling multiple materials on last version, but only if the mesh already have multiple subentities

[fernandot]

I've added a 3DS loader and corrected some bugs, there is still a lot of work to do, but i'll continue adding new features to it...
I've wrote a article about 3DS file, it may help who wanna build a 3DS loader...

Have a look at http://www.ogre3d.org/forums/viewtopic.php?f=11&t=65993

Maybe you can also use ASSIMP to import more formats.

[gdalex]

Do you think you can do a MESH2FBX exporter ?

[gdalex]

Or at least mesh to OBJ, please ?

[fernandot]

Transporter, i didn't know that lib, looks like it will save me a lot of time, ty

gdalex, i was busy with another projects, so i didn't implemented this yet, but i'll try to implement the OBJ exporter first, it is more simple

[Transporter]

@fernandot
You are welcome! Have a look at https://bitbucket.org/transporter/ogreassimp. I patched ogreassimp from jacmoe to get a usable converter for different formats to ogre. I tested a few collada files, and most of them are working fine. I just have to add a few more features like LOD and shader materials.

[fernandot]

Now i'm using bitbucket to share the codes...
Repository: https://bitbucket.org/fernandot/qtmesheditor

Now i'm building it using CMake, I think it will be easier to build it now

I'm still making some changes on QtMeshEditor before releasing the new version...

Transporter,
Thanks for the hint, i've implemented OgreAssimp into QtMeshEditor and it works fine, I even made some changes on OgreAssimp that jacmoe merged to it

[fernandot]

I've just released the new version, it can be downloaded from here: http://www.hogpog.com.br/index.php/en/a ... mesheditor

Thank you all for the hints, i'm not having much time to spend on this project, but i'll try to keep improving it

[fernandot]

I tryied to use Qt5 but i didn't found all runtime dependencies so it was crashing... sorry for those who had problem trying to run it

Now i've changed it back to Qt4 and it should work again

Now i'll try to implement some animation tools...

[Shando]

Hi fernandot,

I have just installed QtMeshEditor, and unfortunately cannot run it as I get a System Error:

"The program can't start because libwinpthread-1.dll is missing from your computer. Try reinstalling the program to fix this problem."

I found a copy of libwinpthread-1.dll and copied it into the QtMeshEditor folder. Now I get another error:

Entry Point Not Found
The procedure entry point InterlockedCompareExchange@12 could not be located in the dynamic link library H:\QtMeshEditor\QtGui4.dll"

Any help would be greatly appreciated as it looks like a very useful tool

Hello Shando,

I've forgot to add some dlls, now it should be ok

I've fixed some other bugs and now i'm trying to add some new features, hope it helps you

Best regards

Fernando

[Shando]

Hi fernandot,

All good now

Thanks for the quick reply.

I'll give it a test and let you know if I come across any bugs.

Hello guys,

I've started implementing the animation tools, first I've implemented only an animation preview, now i'll try to implement some controls over the animations.

The transformations (scale, rotate and translation) made onto the objects are not changing the animation keys, so when an animated object is transformed it will look strange when the animation is applied. I'm currently working to fix this.

Preview of the current version:


Now i've got some extra time to work on this project, so i'll try to improve it as much as i can...

Best Regards.

Fernando

[fernandot]

I've implemented a tool to rename the animations.

PS: still didn't fixed the transformations to animation keys...

Best Regards.

Fernando

[fernandot]

I've updated it to Ogre 1.9.0 and fixed most of the bugs on bone animations when doing transformations, just didn't fixed the bone orientation when the mesh is scaled, if it scales out of the initial ratio it will get strange results...

Now i made a tutorial of how to build QtMeshEditor and how to configure the entire developing ambience to build it

Tutorial

And i've included an option to show the bones, that i got from here: Skeleton Debuger, thanks NickLH

Best Regards.

[fernandot]

I've made some little improvements, the most important is importing skeleton animation from non mesh files and now it imports .fbx files, there was some bug fixes too... like when u import a non mesh file it was importing only the first one, and there was some crashes when importing these files, it may have more bugs, but i'm trying my best during the little time i have to dedicate to this project.

The HogPog site is down 'cause of some issues with the host, while i'm trying to solve it, u may download from this link:

Download

Here we have an example of a .x animated file imported and runing the animation.



Best Regards.

Im having a problem using it. It runs good, but all i see is black scene flickering real quick. Resizing doesn't solve the problem.

Hi fernandot

Very nice job ! thanks for sharing.

You can add axis coordinate system to help the user, I share a little code for that, very easy to use :
