How to create a Spectron (Volumetric Procedural Light)

Hey Paul, how do I use the volumetric Procedural Light feature?
Thanks

Unfortunately all ORBX files are positioned at the center of the scene (0, 0, 0). This is due to Poser providing geometry in "World" coordinates (so all vertices are relative to the center of the scene, rather than having an offset which could be put in an Octane Placement node). To get around this, you can add a Placement node between your Mesh and Geometry Out node in the ORBX file and set the coordinates that you want the proxy there. Another option is that you get set the proxy host mesh item in Poser to "Scatter" (instead of Proxy), and use a single transform in the scatter CSV which contains the offset you want on the proxy mesh. I agree that neither option is super user-friendly, but you are starting to hit the limits of what is possible with the plugin in Poser.
Thanks

Yes, it would be amazing if the plugin could do that - and it's the way I originally intended the proxy system to work, but unfortunately I could not get it to work correctly. You can animation a mesh in Poser, then export to ORBX, then open the ORBX in Standalone and add the Geometry Out node (and connect it to the exported ABC file) and this use that ORBX as the proxy. But it's not as easy as using dials I agree.spartan00j wrote:I had thought if there was a way to access the XYZ trans and rotation or possibly even scale within the plugin itself.

I don't think this is possible, sorry. When you export a scene animation to ORBX/OCS, the Octane API saves the camera position/transform as an animated transform, and removes all geometry and light transforms and just saves their vertices in world space. I think that this point you are hitting the limits of what can be done in Poser with the Octane plugin and may need to look at a host app with more controls, such as Modo, Blender, C4d, etc.So with all that being said, Paul. Is there a way to export an object out with just a camera animation tag that octane will read as if it was a camera. Like if I have two cubes in a scene bouncing around. Instead of using the method I just developed. Is there a way to tell the plug-in to view this object as a camera so it can export out the animation that octane can read?
