The Karma Lens Material is itself essentially a recipe. It isn't currently implemented that way, but it is something we plan to convert over.

But there isn't a Karma Lens Material LOP node type to "host" the recipe.

Thank you goldleaf, it's good to have some sample files. It's rocket science :-)

No problem. We've also just added a related example to the Content Library. It's the Warehouse scene used for some of our launch demos. It has some complex and simple examples of light instances (as well as some other features/workflows).

Just another question: What exactly means in Karma Primary Samples Minimum Samples -1? What is -1?

It means Karma will automatically pick the minimum number of Primary Samples to fire, before it starts the adaptive sampling. We'll have to make a not to clarify that info in the docs/user guide.

Not as far as I know; please log an RFE though, if you'd like this considered for the Scene Graph Details. Thanks!
