specific Performer patches that I can see).
I have recently been playing with the different pfLayer modes using
the pfdConverterMode_flt function (I now see I could use
pfdConverterMode instead) for our flt files.
I want to use PFDECAL_BASE_HIGH_QUALITY as the particular application
suffers from Z fighting when PFDECAL_BASE_FAST is used. I can't reduce
the near/far clip ratio any further.
PFDECAL_BASE_HIGH_QUALITY solves the Z fighting problem, but *some* of
the subfaces tend to "poke through" when they should be hidden by
other parts of the model/scene. Is this is the problem that occurs if
the subfaces are not coplanar with, or bounded by, the parent face?
The problems seem to occur mainly on building models which are
provided with MultiGen's SmartScene tool, which I imagined would only
have subfaces which were coplanar and contained within the parent
face. I checked some of our own models which exhibit the problem and
the subfaces *are* coplanar and entirely bounded by the parent
polygon. Am I missing something?
Any advice gratefully received.
TIA.
Mark.
