[Closed] viewport.setTM and focus object

I working on a piece of script to manipulate viewport in selected object local space.
I did all the stuff for creating the view matrix and everything working fine… until I rotate the view manually. The view seem to focus far far away!
Do I have to scale the view matrix in Z axis? wich value? :curious:

😮 Who!! just tried to scale the view matrix, bad idea, perspective destroyed lol
