I use Maya navigation in all my apps, and I think in InstaMat, Alt + RMB zoom is missing to complete it. I like to zoom base on horizontal mouse movement not vertical(though a option in preference for either would be useful).
I was going to create a post exactly for this same reason. Using Houdini and Maya so my muscle memory is pretty much set for alt + rmb. That would be really nice addition to add
Welcome to the community @SonK !
That’s a great idea, I’ve created a feature request for it.
I’m surprised it’s not there by default. I was trying so hard to figure out how to zoom in on the InstaMAT 3d viewport
