OTOY Forums

Has anyone gotten Modo CSV files to work with Octane standalone? My geometry gets skewed when I try using it and I'm not sure why. I found a script on the forums for exporting instances to a .txt file which works pretty well, but I'd like to be able to use the CSV files.

Hi - not sure how you are generating your CSV files - but if the geometry is skewed - it sounds like the scale is being applied in the wrong order to the rotation in the transformation matrix.

I attached one of the CSV files. I just did a radial emitter and attached the CSV node to the Particle Simulation node, then cached the simulation. This is what produces the CSV.

That CSV file is not in the format required by Octane Standalone. http://render.otoy.com/manuals/Standalo ... age_id=495 has details in the correct format. The OctaneRender for Modo plugin handles all this for you - there is a demo version if you need it see it in action.

Ok, I figured it out. If I freeze the Replicator in Modo, then save the scene for Standalone with "octane.command exportAlembic" then everything works fine.
Or just render from within Modo.


And the Modo CSV exporter is not compatible with Octane? That's too bad.

You shouldn't need to freeze if you are using the plugin. The plugin will not generate a CSV file for replicators. Instead it will pack all the replicator instances inside the Octane Scatter node. You can still see the instance transforms in Octane Standalone when doing this.

No. Octane needs 12 float values per transform (as defined in the Standalone link provided). And the Modo CSV exporter is exporting 3 scale floats, 3 rotation floats and 3 translation floats per instance. There is a spreadsheet available in this forum to convert from the Modo output to the format required by Octane Standalone - but you will need to search these forum back about 12 months to find it (I think rappet posted it).

Replicators don't show up in the Modo plugin with animated particles, ie. from emitters, or in my case a radial emitter. They do show up if you use static particles like a particle cloud.

How would I save out the scene from Modo to see the Octane Scatter node in Standalone? Saving out from the command line only produces an ocs file with an embedded abc node.

Yes - you are right. Replicators with Source Mode of Use Particles are not supported by the plugin - however this should be supported in the next month or two (it's something I am working on).

For Source Mode "Use Particles" you cannot. For other Source Modes, simply open the Viewport and Save to OCS. Open the OCS in Standalone and locate the Scatter node for the replicator - the transforms are store in that node for the replicator.

That's awesome! You rock!

BTW thanks for answering questions over the weekend. Otoy, take notice. Paul is alright.
