Houdini Translate SOP not supported? / Alembic Delayed Load Primitives support

[tobiasroesli]

Hello,

I want to use Vantage for previsual.

The problem is that the following two points are not working at the moment:

1. seams to me that the Houdini Translate SOP is not supported at the moment. If I make two Keyframes and export the vrscene it's just static then. Camera on the other hand works fine with animation. Any Tricks? I already baked the keyframes, no success.

2. If you use the "Alembic Delayed Load Primitives" workflow it's not showing any shaders in Vantage.
You have to switch in the Alembic SOP to "Unpack Alembic Delayed Load Primitives" which makes the file big. Textures are shown then. Is there any plan to make it work without unpacking the Alembic?

PS: Could somebody at Chaos give me access to the Vantage Nightlies?


Cheers
Tobias

Sorry, I forgot, I use Vantage Version: 1.8.1, Build: 1433992, Jul 18 2022

Sorry, we don't provide nightly builds. I can't answer the Houdini question as I don't have it. Someone else will have to check this.

Honestly, we haven't looked at supporting the vrscene features specific to V-Ray for Houdini.

Can you send us simple example scenes of the setups you are using, so we can assess whether we can implement them quickly or not ?

Hey vladimir.nedev ,

on the following link you find a Houdini Scene with a simple animation. Camera is moving up and the cube is rotating and also moving up.
https://we.tl/t-s0pmlL46GO

When I import this vrscene into Vantage it only shows the camera animation.
I also rendered the 25 frames animation with Deadline and Vray Standalone. So the animation is in the vrscene otherwise Vray Standalone would not render the movement of the cube.

I also checked the vrscene with Maya and it seams that Vray for Maya also shows no animationon of the cube.

Thanks for the scene.
It uses an animated Instancer2 object.
Vantage doesn't support animation on these objects yet, but we have some plans to support it in the future (not immediate).

Hi vladimir.nedev,

do you have some news about this issue descriped above?

I was just testing and I still get any animation out of Houdini for Vantage.
I use Version 1.8.4.

Maya still works like expected.
