Clipping rendering region to remove foreground without tilting camera

[Nader1328]

I have a 25 story building for which I can setup a properly clipped rendered area. It reduces context from left and right and bottom (foreground). Same in D5 Render and Blender. Not much luck in Twinmotion, accomplishing it or finding a reference to it in the docs.

I have to move far to get the whole building in with a reasonable focal lens. So, there is lots of foreground and building on the sides. I wish it was possible to frame the rendering in a vertical 8K rectangle.

Even turning a monitor vertical doesn’t solve the problem, the building is framed OK, almost OK, but the foreground and the sky take up about 90% of the rendering region. I can’t “freeze” my location and then zoom in to the region I want rendered. Sort of like a shift lens in the physical world.

I try to look perpendicular to the building, then move to the left so that it is not cut of by edges of building across the street.

Best in TM first link, goal in second link from D5, third link from REVIT.

Any suggestions would be appreciated.

PS: New to TM. Pretty good in Blender and D5 Render.

I am glad to report that I finally found a sufficiently reasonable alternative to defining a crop region in the camera view. The work is different from REVIT where you have numerical control of the camera positions.
This solution is just as acceptable after you tune up your fingers’ motor controls.

First, when I refer tp specific mouse buttons and related keyboard presses, it is with the interface set to emulated REVIT/Archicad.

I first find the best camera position for the view I need. It is a dense urban conditions and I need to show the front of the building as full as possible as well as the side on the angled street.

In my camera lens I have set “Parallelization” on. So, as I move or rotate the scene or the camera, vertical edges remain vertical. This is an architectural view, not necessary or desired for other uses.

Using the left mouse button I rotate the scene, Using RMB (Right Mouse Button) so that I have the bottom of the building just past the nearest edge of the foreground building. I use the LMB to then rotate my camera in place so that I have most of the building front as flat as possible to the view.

I then will have lots of foreground and areas to the sides of the building to crop. As in REVIT one could define a crop region graphically, here in TM I found that the camera back (available only after you define an image in the Media). I set the width to crop horizontally and then change the height of the film area to crop above and below the main subject.

Again using the LMB (Set for REVIT) in combination with the arrow keys or QWESAD etc, keys, I move the image within the frame.

It is not as direct as you have it in REVIT, but it is more photographer like approach.

You can then use the camera FOV or Focal Length to further adjust the perspective distortion you need. Of course you may have to re-frame the view as you see fit to crop the contents.

Hope this helps. It took me a few days to get used to it, but seems to be intuitive enough.

This is now a quick start. On to lighting and entourage to bring it some life.
