Great program - I know it well. Have used it with Twilight Render many times.

When using a TR spherical projection with a constant 35MM film size, and experimenting with different size focal lengths from 5 to 20 to 100 (see images) I found the SketchUp view changes, prior to the rendering but the resulting renderings appear the same?
Please advise what's the best way to determine settings, mostly if not for all interior shots using spherical projection settings for a 360 panorama.
Thank you for your question Billy G.
Render spherical images at 2:1 ratio width to height. So, 2000 px wide and 1000 px high, or 4000 px wide and 2000 px high (probably the maximum I would go with rendering something for display via the internet)
If you change focal length you MUST right-click your Scene Tab in SketchUp and choose "update" for the scene, otherwise the change will not be registered. If you want to try different focal lengths, may I suggest creating several different scenes with different focal lengths?
But for rendering spherical interiors, since it is a spherical image, you will most likely, at least in architectural situations, keep your FOV at around 50. The only exception could be for a very narrow space such as a small bathroom or narrow entry hall. Then you could maybe venture to 60 or 70. But I would try to keep it around 35-55. (35 is similar to the "catch-all" lenses of old point-and-shoot basic cameras that were sold everywhere before digital cameras were popular. 50-55 is similar to the basic lens that came with a little bit higher end mid-range cameras like your basic decent Canon or Pentax or what have you.
Since you are rendering the image as a spherical image, it will result in that you are seeing the entire interior space in spherical format, only the FOV will make the spherical image appear to be either zoomed in or zoomed out when you open it to take a look on the web when it is
