Correct setup of Maya - Blender pipeline, alembic & scale

Hi guys, apologies I can’t seem to find the information I’m looking for already out there.

I’ve been happily using Ayon as a Maya based Pipeline for years and now have ended up in a new place based in Blender with a few Maya users.

I’ve deployed Ayon to a server and it’s all running well.

However when testing publishing a model from Maya and loading as alembic into blender, nothing I do to the ayon server changes the import model size -

Also when I publish a new version of the model in Maya and update it in blender nothing changes.

Here I am trying to test it out with an asset -

I think perhaps the model not updating is to do with pyside2?
https://help.ayon.app/en/help/articles/6836825-configure-blender-addon

I have attempted to follow the instructions here to update to pyside2 however get errors I’m trying to get around.

ERROR: Could not find a version that satisfies the requirement PySide2 (from versions: none)
ERROR: No matching distribution found for PySide2

Also the company owner is using blender on a Mac & there’s no instructions on that website to do this on his mac. Can anyone confirm if this is the issue? I’d rather not have to get all of my users to try and attempt to do this step.

Thanks in advanced for any help.

To narrow this down I’ve published a basic cube with an extrusion as a blend file and “append” it in to a new blend scene via Ayon, I then update the cube blend publish to a new version and try to update inside blender and it fails to update. It can load each model individually but not update from one to the next.

Is this maybe because this studio is in blender 4.5 and Ayon isn’t fully compatible yet?

This part should be updated in docs.
In short, the recent versions of Blender addons should fulfill the PySide requirment automatically on starting the application from the launcher.

Hey, thanks yea I did a reinstall at some point and saw it does add PySide6 now.

Still doesn’t work at all updating published assets in blender 4.5. Is it not yet compatible with Ayon?

As far as I know, blender 4.5 should be working fine.
Also, keep in mind to add --python-use-system-env argument to blender in application addon settings.

Thanks, I didn’t see that in the docs anywhere. Do you mean to add it here?

Really frustrating though is just publishing a cube as a .blend and trying to update to v002 of the cube gives me a failed to open error.

@mustafa_jafar @BigRoy Any further ideas guys?
I’ve tested and everything is working fine in Maya. Blender can load files totally fine, just fails to repath to other versions each time.

Any suggestions of what to try here would be appreciated. The studio I’ve started working for setting this up has a lot of potential.

Hi, just after quick glimpse your ayon-blender addon been heavily outdated, like months…so pls update to latest 1.0.4 and all respective addons e.g. ayon-core.

All should be working fine then…

Hello @polyshark , I’ve moved your comment about blender linking to a sperate post. I believe this will make it easier to follow up.
