How to make LightFilters available in GafferThree?
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?
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.
