What do you mean by saying that it's "defunct"? Was Modo discontinued by the Foundry?

Anyway, to answer your question, you can apply Normal SOP (set to vertices) to a selection of primitives (faces). This should get you the same result as setting up a single smoothing group in Modo/3DS.

EDIT: To answer my own question... Holy cow, it is indeed defunct:

What a way go shut down a software with 20 years of history... There was a point in time, not so long ago, when I was about to purchase a Modo license, and thank God that I didn't. But yeah, when you are bought by a corp, you usually end up like this, so I'm not surprised by this turn of events. I just pity the people who invested their time in the program.

If you want to see the boolean method in action, there's a sample scene posted in this post [www.sidefx.com].

I see. Yes, it's a new Copernicus (COP) node introduced in 20.5.

Glow is basically a blur applied on a range of bright pixels. You can reproduce it with COP2s by isolating high pixel values, desaturating them slightly, blurring them, ramping up brightness, and comping the result back with the original plate (Screen or Add).

The attached image demonstrates a basic glow setup in COP2.
