Maybe adjust the max_intersections value...it affects the number of
intersections found when testing against an object. If it simply isn't
finding the front surfaces of the blob because it's tested as many as it
can, it might cause this artifact.
4.10.7 Max_Intersections
POV-Ray uses a set of internal stacks to collect ray/object intersection
points. The usual maximum number of entries in these I-Stacks is 64.
Complex scenes may cause these stacks to overflow. POV-Ray doesn't stop
but it may incorrectly render your scene. When POV-Ray finishes
rendering, a number of statistics are displayed. If you see I-Stack
Overflows reported in the statistics you should increase the stack size.
Add a global setting to your scene as follows:
global_settings { max_intersections Integer }
If the I-Stack Overflows remain increase this value until they stop.
