3D cardboard with Synfig

Hello everyone!
My son recently gave me a cardboard viewer, and I immediately started creating my own 3D animations.

Well, it’s just a trial run for now.
Synfig is well-suited to this kind of experiment because you can precisely adjust the image offset, which ultimately creates that 3D effect.

I’ll let you see what it looks like initially.

It’s just a static simulation to calculate different depths by shifting a few pixels.

My question is whether you can duplicate a spline and apply an offset so that it ends up in the right eyepiece…
Thanks for your answers.

You can use converters to do it.
