not sure if it will help, or is even related to "the issue", but if I change the
"bubble_r" to "(bubble_r - epsilon)" in the five spheres following comment "Add

quick comment re "new to POV-Ray".  you have five identical (apart from
location) spheres.  have a look at macros, they're ideal in such a situation.
