Hello everyone! I really hope Google Translate gets my point across without distorting it too much. So, I'll try to explain again what the addon does.

With it, you can transform a distorted reference image into a more or less correct one.
Yes, something similar can be done in Photoshop. But Photoshop doesn't allow you to set precise dimensions and references.

In the attached images, I've tried to demonstrate the principle of how you can modify an image.

Naturally, I assume that you should know at least some of the parameters—for example, the width or height of an object. You draw a rectangle in MOI3D (for example) and then "pin" the image to the places where it "should be."
Click on the image—click on the corner of the geometry; click on the image—click on the corner.
Placed... Then click Update—the image will be positioned at the designated corners. But your middle section is curved, which should be vertically straight.

Great – click on the points that shouldn't change with the control (they'll turn blue) – they'll "freeze."
And then point to the curved line where it should be vertical – that part of the image will move in the desired direction. Basically, it's like a mix of Distort and Warp in Photoshop.
