Smooth zooming in viewport I have experience with Maya and C4D and I’ve become very accustomed to the way view-port navigation works in them. I know that one can set the key-mapping to that of industry standard; however then the orthographic views’ key-maps on the numpad gets changed (which is a no no).

So I’ve set up different key-mapping for camera panning and rotating on the Blender key-maps but I want to add the function to smooth zoom via ALT and RIGHT CLICK and dragging the mouse up and/or down. I know that it is mapped to CTRL and MIDDLE MOUSE on the default Blender key-map.

I realize I can just go into the settings and do it manually but I’m afraid of effing it up too much. So I’m hoping that someone here might have already sorted this out (hopefully).

Thanks a million
You can do that zooming for sure if you know how to add a new keymap:

Go in that keymap setting panel and choose the 3D-view(global) panel, scroll down to see that Add New Button. Press it, it will give you a None keymap.

Setting up the identifier field with the thing you want, in the zoom case view3d.zoom



And then setup rest of the key setting, you shouldn't need other details setting for your task.
