Hello!

Is it possible to bake transparent materials so the underlying object/ material is sampled into the map?

This cannot be easily done as transparency is sampled as either black or alpha value if alpha is enabled in your kernel settings.

The baking system stops tracing at the first ray hit, which means that it will just output the color value of the surface you are intending to bake. If there's something behind, you'll need to bake it separately.

Also, take into account that when using transparency, the result depends on your point of view. You may however specify Use baking position if you are interested in just one camera position.

Please take a look at my explanation about how the baking camera rays work here and depending on the result you expect you may find a way to do so using the Revert baking flag. You may also read about all the baking camera setting in the 3.0 new features post if you haven't yet.

Thank you for the explanation, mojave!
My hope was there might be a trick to get the refracted background sampled.
