I’m trying to follow this tutorial here: https://www.youtube.com/watch?v=IXCY5Mq3isU
But I can’t figure out how to get the secondary view to display the background image on a different axis.
My main window is setup for Y (up down) X (left right) I need to secondary view to be Y (up down) z (left right) [I think?] How would I go about doing this?
Set up two background images and for each set the view you want to see it (Top / Front / Right etc). Then set each viewport to that correct view using the numpad keys/ Ensure each view is also in the orthographic view (toggle between perspective and orthographic views)
See http://www.blender.org/manual/editors/3dview/background_images.html?highlight=background
Unless you are using an ancient version of blender forget that tutorial and use one of the million tutorials that are used with a version of blender made within the last 5 years.
