As a newcomer to Blender, I'm trying to reproduce a few workflow scenarios I once used in Bryce, but now in Blender I can't figure out how to do one simple task that was the backbone of much of my output:
In Bryce I could render a scene, then using a bounding box to select an area, render the selection and see a newly rendered scene that would then fill the 3d view (called "Zoom to Selection" in Bryce). I could then select another area in that "new" scene, render that selection, and so on, and so on (re-iteratively) quite a ways. Essentially you are slowly zooming in. Each new render was detailed enough to see what I wanted to zoom into further.
The closest I've found in Blender is the "Render Border" function. Unfortunately, the rendered selection is too undetailed to see well enough to effectively zoom a second time, much less allow for successive iterations. Also, "rendered border" only fills the selected area within the "camera" view. If the selected area is near a border of the main view, then zooming the view to see greater detail in the selection results in part of the image scrolling outside any possible view.
At any rate, if anyone here has worked with the "Zoom to Selection" feature in Bryce, and has a suggestion as to how to recreate it in Blender, I would be overjoyed!
