How to use Octane ORBX SOP ?

[fantome]

Hi guys ,

I am trying to load a simple orbx file

trex_08.orbx

(700.51 KiB) Downloaded 244 times

inside houdini with the ORBX SOP, but it doesn't display anything at render time.
The orbx works perfectly in standalone, but i can't make it work in houdini, i might be doing something wrong but i don't know what ?
I use houdini Indie 17.5 with Octane 2018.1.3 on windows.

Cheers

Hi,

Have you tried to import the .orbx file once it has a geometry output or a render target node as the final root node?

Thanks,

Thanks for your answer Juanjo,

I have try both of your solution but none of them work.
I have the following error message :

Are you sure that it is not related to an Indie License restriction that doesn't allow orbx access ?

I have attach the orbx scene. It does work smoothly in standalone but not with the Orbx SOP.

Hmm, somehow an alembic node can't be connected directly to the internal node tree built by the plugin to support the .orbx files. I'll investigate it, but meanwhile, a workaround is to add a geometry group node to the .orbx file.

Thanks,

Thanks a lot for your great support Juanjo, it works perfectly with the group node.
This is really a great feature. Thanks for implementing this.

For the next plugin build, I've updated the .orbx referencing code to support these kinds of files without adding additional nodes.

Thanks,

Hi juanjo ,

In OctaneRender 2020.1 for Houdini Beta build 2020.1.0.1 XB2 the orbx proxy still need a Group and a Geometry Output to work properly.
So it looks that the correction you've done recently is not working ?

Hmm, the fix should be there. Do you have this problem again with your orbx file attached to this topic, or does it happen with another file?

Thanks,
