Maya: Implementation of Ornatrix product type

[moonyuet]

Changelog Description

Implementation of Ornatrix Exports in Maya

• Ornatrix Rig: Publishing Ornatrix or any Ornatrix related objects. If there are any painted map(s) by user, they are published too and the published maps would be located in the {your publish folder}/resources
• Ornatrix Cache: Publishing Ornatrix fur simulation as Ornatrix Alembic cache. It can be loaded as Arnold StandIn, Vray Proxy and Alembic reference while it can be loaded as the file cache in the Ornatrix-related GuideFromMeshNode.

Additional info

Although Ornatrix cache loader can add HairfromGuideNode into the operator stack, it can only be shown once into the stack editor (due to some api limitation). Users need to select the objects they want to load the file cache in order to add the cached nodes "safely" into the operator stack. (But users can still find the guide node in the container set)

Requires ayon-core update

Please test along with the branch from this PR ynput/ayon-core#734, otherwise it will error out the collect resources path when publishing

This error hints at that the ayon-core PR branch is not used:

Testing notes:

Ornatrix Rig

1. Create Ornatrix Rig with your geometry which is assigned with ornatrix fur
2. Publish
3. If the content doesn't include the Ornatrix guide, it can't pass the validator.
4. Texture maps and ma scene would be published along with rigsettings which stores all the ornatrix related parameters.
5. Start new scene and load the reference scene of the published ornatrix rig
6. Once you start publisher, the ornatrix cache will be automatically created with the references of the ornatrix rig.
7. If you load the ornatrix cache, it will create group with a mesh shape which includes the GuideFromMeshNode storing the abc file cache.
8. You can also load the ornatrix cache with Arnold StandIn, Vray Proxy and Ornatrix Alembic
9. You can also connect your ornatrix rig with the same meshes located in pointcache and animation product type (select your mesh from pointcache and animation product type first and then your ornatrix product type)

Im getting error when trying publish oxrigMain because of my source file textures

my files sits within the work folder in ../ornatrix_maps subfolder

@LiborBatek have you installed the addon with this branch? ynput/ayon-core#734

[LiborBatek]

@moonyuet ouch I have overlooked that needed branch! my bad...sry will do another testing round!

[iLLiCiTiT]

Please test along with the branch from this PR ynput/ayon-core#734, otherwise it will error out the collect resources path when publishing

If that PR is required for this PR to work, then you have to raise required version of ayon-core to >0.4.0 in package.py.

so I was able to produce publish of oxrig this time and load it as oxGroom into new workfile but I was not able to use connect action...

it didnt print any log into script editor nor console tho

Im not sure with published .ma representation as it behaves as before bringing in the full character asset with ornatrix setup - do we want that? maybe by first using the locally duplicated meshShape for setting up the Ornatrix rig might do? if we want to follow such workflow...

I wasnt able to perform Load OxCache from the published Ornatrix setup (as a side product when published)? whats the supposed workflow for it?

[LiborBatek]

as I wasnt able to reconnect to my pointcache animated character I didnt test to produce oxCache for particular shot animation yet... I will try at least on manually connected oxRig to see how it behaves for publishing process...

Once you loaded the Oxcache family, you can find the guide node with cached abc in the container set.

[LiborBatek]

so I was also able to produce oxCache publish on manually setuped oxRig> pointcache animation for particular shot but there is no currently any Action in manage available to the user atm?!

there is a bug for this, will fix it as soon as possible.

[LiborBatek]

when manually bringing the published oxCache into the workfile by performing File>Import>OrnatrixAlembic there is a cache loaded into my active workfile but it is not sequenceaka lacks animation and also doesnt look as the oxRig setup ...the hair strands are ackwardly scaled aka thick?!

Note: as I have inspected the products created it seems that the ackward look been caused by partial stack of modifiers exported (just guides but not thickness mod etc.) dont know for what reason tho

[moonyuet]

I guess there is a case which geometry is with more than one hair shape and it can still be published?

I can still publish without the validator btw.

[BigRoy]

Based on the discussion here me and @moonyuet have decided to:

• Lift the single hair shape validation/restriction.
• Remove the loader for Ornatrix Groom .ZIP (which with that may also remove the Extraction of that actually because then it's unused?)
• Remove the loader for "Load Ornatrix Cache with Hair Guide" because it's complicated to get it working from an artist's perspective and it seems to suffer from the same bugs.

That brings this PR back to being able to generate Ornatrix RIGs and Alembic caches.

I'll port over the things I remove to another PR but turn that into a draft just so we can release the first feature set now @m-u-r-p-h-y @tatiana-ynput. @moonyuet also mentioned that most likely the client will be using the Extracted alembics anyway by loading into e.g. proxies or alike.

[BigRoy]

So it now works.

HOWEVER, please be aware that the Ornatrix Alembic Loader does NOT import the animation of the cache.

I spent way too much time thinking the export didn't include the animation - just to figure out that importer doesn't load it. Arnold Standins do load them and render fine.

@moonyuet it'd be good if you can do review.

We've reverted some logic closer to what @LiborBatek reported issues with - but I was unable whatsoever to reproduce those issues (in any way!), so let's take them with a grain of salt and assume it was user error at the time.

I'll mark it approved so you can check it one more @moonyuet and then can merge it.

Okay good. I will check tomorrow and merge it. Thank you so much for the help!

[moonyuet]

@BigRoy Do a simple test and it looks good and we can merge this.
