I get the following parse error when trying to use Camera35mm_Autofocus,
when using POV-Ray 3.7 beta 37a:
"line 433: Parse Error: Attempt to access uninitialized array element."
No error occurs with version 3.6 or Megapov.

All the best,
Thomas

Sorry for the mess I write (as usual). Contrary to what I said above, I get
the error *also* with version 3.6 or megapov :-(
I probably is something I do wrong, but I have not a clue about what it can
be as I use - I guess - the demo scene as is.

Hmm, could be something like none of the autofocus samples actually found the
object - but I'l have to take a closer look and do some debugging.
Thanks for the report.
Cheers,
Edouard.

I can recreate it by having an extremely small object, so no autofocus samples
hit it...
You can try #declaring 'Camera35mm_AutofocusTightness' to a wider value like 1.0
(which means the who screen) or 'Camera35mm_AutofocusSamples' to a higher
number, so there are enough samples that the code hit the object.
I'll edit my code to print a warning, and set the autofocus point to the objects
center.
Cheers,
Edouard.

Excellent and thanks indeed! I shall try this as soon as my present render
is finished. The FocusObj is indeed very small in relation to the scene. I
had not considered that possibility.

Works!
I my case, I could scale-up the FocusObj to proper size.
