• If you want to change the target object, toggle out of the camera view, then press the Create Turnaround Camera button again.
• Every time you change the parameter value, animation will not automatically update that parameter. So, please toggle out of the camera view, then press the Create Turnaround Camera button again.

These problems occur because my coding skill is still not perfect, so I will continue to find ways to fix it in the next versions.

• Create turnaround camera with 1 click.
• Easily adjust rotate speed and number of frames of animation duration.
• Smoothly switch between objects and angles.

Every time you complete a model, the first thing you do is continue to spend time setting up the camera turnaround to render the presentation video. This is where my addons help you do it with just 1 click.

This is the first version, so it may still have errors or inappropriate features. I will continue to update this addon in future versions.
