I am having a difficult time having all images at the same scale in MOI.

In Photoshop I have all 4 images loaded as layers in a single PSD file. And I arrange them so they line up and are the same scale. The PSD is 1552x960.

I then export each layer as a separate png.

The Top and Side reference images have a dimension of 1552X960

The Front and rear are 858X960.

in Blender I import all 4 png files as "Image Planes" (not as reference or background images) at the intersection of the X Y Z axis.

Since they all have same height of 960, they maintain scale. All I need to do is rotate them into position.

in MOI there is no option to import the reference images at the X Y Z axis. And I have to manually scale them by guess, which I find very tedious and difficult.

I was hoping in the Images properties button it would have allowed the entering of the actual images dimensions. That way all would have same height and no need to scale.

However under the properties button I see the file path to the reference images.

Is there a way to import reference images into MOI so they maintain their scale?
