IES light conversion

[riggles]

Testing out light emitter conversion in the plugin. IES lighting distribution is supported, but only area and point light conversion is included. In MODO, IES lighting is a different light type, Photometric. Can we add support for this light type so that, upon conversion, a mesh is created and the same IES file is now connected to the distribution channel of the emitter? I'm converting a MODO scene with lots of instanced Photometric lights, but I have convert them all to point lights first, then convert to emitters, and then reconnect the IES files. Would be nice to skip the first and last steps in the future.

Good suggestion. Do all your instanced lights have the same direction/intensity? With the plugin you will need to "Convert to Emitter" each light and each will have it's own material (but you could add them all to a shader group and assign a single material if you want to adjust them all at once).

In this particular scene there are a few different IES lights in different groups of instances. I made an error in my original post. Existing light instances won't update to add the mesh emitter that's been added to the original light hierarchy. I have to re-instance the original after conversion (with hierarchy enabled) if I want to avoid creating a bunch of duplicate materials/overrides like you mentioned. But that seems more like a MODO instancing limitation than anything.

Would also be cool if the MODO light material color came over in the conversion as well.

Where do IES files get plugged into? Is it loaded as an rgb texture?

IES lighting is covered in the manual at http://render.otoy.com/manuals/Modo/?page_id=79 although the new Create Octane Emitter button supersedes this info, and automatically pulls the IES filename from the Modo light. You get the best out of IES lights if you plug a spherical projection into the IE image node.
