[VMAYA-9095] [HOU-1286] Reference mesh for alembics

[LeoYfver]

Using reference objects and rest attribut works perfect for native geometry and packed primities but not for alembics. Is this something that can get fixed?
For extra info I use the sampler node with pointReference connected to an extraTex in the renderchannels.

also a small note:
If you select an object from the menu in this example an object called pRef it wont work, the whole path has to be written as in /obj/pRef.

Hello, apologies for the late reply. I wanted to check if a solution that does not involve the core team can be found. It seems like I'll have to log it as a feature request for V-Ray. I'll keep you posted!

// while messing around, I noticed the pointObject output is returning the initial position of the mesh in the alembic file - to me this seems like a bug but maybe it could work for you guys until an actual solution is found ?

All the best!

[LeoYfver]

wondering if this has been looked on?
Im gonna add a feature request to. Would it be possible to have an alembic and sample the position from an arbitrary frame in object properties. so FOr an alembic with 100 frames i get the rest position from frame 1

Hey, Alexis,

yup, it's being looked into, I've also updated the issue description with your request. I'll ping you as soon as we've got something.

All the best!

Thanks! another thing. Rest attributes on alembics doesnt get picked up

"Rest attributes on alembics doesnt get picked up"

Yes, it's exactly the same issue. Rest attributes are exported as reference mesh and there is no reference mesh support for Alembics (GeomMeshFile plugin).

[LeoYfver]

Even if its a point attribute named rest exported from houdini?

Because you can pick up that vector with a user color i guess?

[LeoYfver]

Do you btw think that the reference frame is feasible to do at all? The one i i mentioned above

[bdancer]

It doesn't matter where data is coming from. The feature is just not there.

[LeoYfver]

Its not there as in it will never be?

> Its not there as in it will never be?

It's not there like if must be implemented

If you could make me a test scene it'll be great.

[LeoYfver]

maybe we can pm if there is still confusion.

Here is the scene:
