Hey! I just have a quick question: I have two Houdini projects open. In one of them, I can zoom in and out with the scroll wheel. No extra button presses required. In the other, I have to hold down alt in order to use the scroll wheel to zoom. Why is this? How do I set this project up so that I can zoom in and out without holding alt?

When You are in camera mode you can zoom without holding alt.
When You are not you need to hold alt to activate volatile camera navigation.
