How to make LightFilters available in GafferThree?

Hi,

I'm experimenting with writing custom light filters and was wondering how it would be possible to make them accessible in the GafferThree?

I see them being picked up in the ArnoldShadingNode dropdown, so I'm wondering if there's anything that needs to be added in the metadata for Katana to identify it as a lightfilter?

Thanks

Hi!


Attached a simple shader example and a Katana scene to showcase a use of a custom filter in KtoA. The trick is to make the node type AI_NODE_SHADER and the output type AI_TYPE_NONE. This way the filter will show up when selecting the material for the lightFilter. It won't show up in GafferThree's lightfilter/viewer/Type list, that requires a lot more work and a custom viewport plugin.
