Hi all! I have a question. How i can make a passes in Houdini. I've found just diffuse, specular, normal. Can i make for example occlusion pass? or environment one?

you need to create a “take” there is a tutorial pdf on the tutorial section, has the picture of an old camera.

after doing that you can use the occlusion shader into all the objects in the scene.

if you want just diffuse or spec there is a pass inside the mantra node.
