Model with animation support?

[katopz]

Hi, Thanks for creating this. You're life saver!

BTW i'm not sure model with animation support?
Far as I try rotation is broken somehow and maybe need a way to handle animation clip (and also manual rotate the turret later)

The turret 3d model is here https://sketchfab.com/3d-models/missiletower-building002-9e0b1bcc84734c69a21e9c865fcfc172

Thanks again.

Hi @katopz !
Thanks for the kind words.
Very timely :)

• I just noticed that rotation & scale are broken this afternoon (only for collection instances).
  I am almost done with the fix (rotation works, for some weird reason, the scale does not get exported to the gltf files, still investigating). A new version of the Blender plugin & bevy_gltf_blueprints should be out in a few hours max
• There is some support for animations (a very small convenience wrapper around how the animations work in Bevy) , but I haven't explicitly mentioned it yet, as it is still work in progress. I'll try to post something about that a bit later.

@katopz , the issue with rotation & scaling is now resolved, please make sure to use the latest version of the Blender add-on :)
I'll ping you when I have some more things to share regarding animation

[katopz]

Thanks!

Turret base look in place now but other object gone wild.

and I can see a lot of output continuous yelling.

This yelling also happen before the fix i think (should be other issue).

Anyhow load the 3d model only to the scene also appear the same,
maybe it's because the 3d model itself not playing nicely with Bevy.

I will try again with less complex 3d model to find the root cause. 🤔

It seems there are multiple issues going on at the same time:

• the model itself has issues for me , even in Blender, I had to forcefully rotate it by 90° to get it to work
• on your latest picture it looks like you have not exported the gltf file with the "Y-Up" option toggled
• I tried it with this model : https://sketchfab.com/3d-models/robot-courier-all-terrain-free-low-poly-model-2626b4a125ed4623936afc76c7a6483d and it seemed to work out of the box

• the continuous "yelling" , means something is not normal when loading the gltf files, it seems Bevy is unloading the files before they are done loading completely, I need to check if that happens inside Bevy without the plugins too, because that a big issue

[kaosat-dev]

It seems the handles to the gltf assets are being dropped prematurely, still investigating.
I was working on some other improvements that I will push first, but i'll try to fix this asap

[kaosat-dev]

Hi @katopz I started investigating the issue in more details, sorry for the delay , could you please tell me

• if you exported the scene using the standard Blender gltf exporter or the auto_gltf_exporter (the one in this repo?)
• you used the advanced example as a basis right ?
  Thanks in advance :)

[katopz]

Hi, No worry for the delay just a hobby here :)

• yes and yes (v 0.3 at that time).
• yes.

Only diff now should be y-up (already set to y-up now) when export and bevy 0.11.3 (have to lock at 0.11.3 or crash due to bevyengine/bevy#9389 )

I can understand about gltf limitation (vary import/export),
maybe we need the working animation examples and precise config.
The model itself can be and fix and modify in blender to match our requirements/config anyhow.

btw i try 0.5 but can't trigger auto export after modify and save anymore not sure how i can manually export (as i recall it should auto export for me am i right?)

Thanks!

[mlflabs]

Could you provide simple code example how to get animations playing?

[kaosat-dev]

@katopz & @mlflabs I am currently fixing a small issue ,improving the API and adding an example for animations, I'll let you know once it is ready. Because of the Bevy issue #29 that is fixed in V0.12, it is a bit complicated , as most of my test models with animations get unloaded wildly haha.

@katopz thanks for the details :)
Yes auto-export is the best way (and the only way to use Blueprints easilly).
I upgraded/improved the UI/UX of the Blender addon, if you have issues with that part, please open an issue for it :)

[kaosat-dev]

@katopz & @mlflabs I just released a new version of bevy_gltf_blueprints with animation support & example :)
you can check out the example here : https://github.com/kaosat-dev/Blender_bevy_components_workflow/tree/main/examples/animation, particularly this part on how to trigger/control animations (it is standard Bevy with an extra helper I added to make things a bit simpler .

Additional fyi for you @katopz , it works really well with the latest version of the Blender Addon, so if you have issues/questions for that, please do not hesitate :)

Have fun !

[katopz]

Thanks! @kaosat-dev This should be fun! I'll get back to try this after I'm done with llm.

Anyway I owed you a beer! Do ping me if you come to Bangkok. :)

[kaosat-dev]

Haha thank you , and gladly @katopz :) Never been there before, would love to visit one day ;)
