Hi everyone,

there are two keywords mentioned in PoV3.1 docs section Inverse, as are
internal_highlights and internal_reflections.
As far as I know, these are nowhere explained otherwise in the docs nor
they appear in the doc's keyword list.
I tried to use them as statements in interior{} as well as in
texture{finish{}} (just like phong or specular) but they only are parsed
as 'undeclared identifiers', that means, that PoV3.1 dos not know these
keywords.

Does anyone (perhaps from the PoV team?) know something more about these
'forgotten' features?
