Hello,
as a newbie I`m struggling with some light setups. How do you can make fog rays in houdini18? Found some tips about a atmosphere node and the litfog shader, but the atmosphere node is noted as deprecated and I have no idea to set this shader up. Any help is welcome.

Tia,
Jochen

Here you go.

Box with uniformvolume shader and a light with projection map.

Just hit render.

Thank´s Werner,
it´s a start for me, you build your own uniformvolume shader, right?

No, you can crab it from the Material Palette and just assign it to any geometry.

Thank you
