  Known bugs in POV-Ray version 3.5  

Following is a listing of known bugs in POV-Ray 3.5. Most likely they will not be corrected until POV-Ray 4.0 (which is some way off).

  Bugs inherited from POV-Ray 3.1 and older versions  

These bugs, while they have been around for a long time have not been fixed in POV-Ray 3.5. In most cases they do not cause any serious problems, but it is still possible you find them while using POV-Ray. Many of them are related to precision in some way and can be worked around by changing the scale of the scene.
