When i use orbit (space+LKM) some time viewport rotated and loose my object from FOV

For example 3dsmax have options for rotate viewport only around selected object/face… etc.
In C4D we use mouse pointer every time for center selection

But i dont find anything for Houdini (
How it is possible to control that?

Select the object and spacebar & G or for all objects spacebar & A

in the manual under /basics/view

no
i dont want chage viewport setting (zoom/dolly/pos), only center of orbit!
most 3d soft have this function!

you can use SPACE + Z to set the center of orbit

thanks! thats better
but some times after space+z my viewport loose horizont (virtual camera change roll/rotattion)

how i can roll my viewport?

Hold down Ctrl while tumbling with the left mouse button to get roll.

There is a help page in the Houdini help that goes through most of the viewport basics, search for “tumble” and pick “View the scene”.

Big thanks!
