Layering is broken in Performer 2.0 and is fixed in 2.0.1 and 2.1 .

Attached is some earlier email discussing the problem ... I'll be happy to send
the small test file mentioned in the attachements (zsubf.flt) to anyone who is
interested.

Regards.

You're welcome :)  I'll check out the WEB page then!

Yeah it was great fun and work ... afterwards I had some time off in Amsterdam
and London. :-)

Now it looks like Graham and Co. want to package these cool things into a demo
for the iR CDROM!  No rest for the wicked ;)

I told Jenny I'd be sending you all a loader update in a week or so ... some
refinements and bugs fixes.  Next, I begin developing some new feature support,
i.e. the OpenFlight V15.2 loader is coming (V15.[01] == V14.2) "soon".

Regards.

Subject: Re: layer problem


I've made these changes, but the layer behavior is not different using my test
case zsubf.flt .  I had already taken steps that effectively give the same
state.  I had called perfly -q0 -Q0 to disable your sharing stuff and had added
PFSTATE_DECAL inheritance to the loader.

The PFDECAL_BASE_FAST and PFDECAL_BASE_DISPLACE with[out] PFDECAL_LAYER_OFFSET
do not work using IRISGL as I said before.  I've read the pfLayer and pfDecal
man pages wrt NOTES and BUGS.  pfDecal gives a better indication that problems
are likely using _DISPLACE mode.  Both man pages imply that adding _OFFSET to
displace will correct any problems but this is not 100% true.  Could some
clearer language be added to these man pages?  I would say that support for
decals and transparency rate up with texturing in terms of "must be right".

BTW: PFSTATE_SHADEMODEL is not mentioned in the pf[Geo]State man pages.

Thanks again.
