I've taken and modified the Reflect function so I can pass it a pointer to a
finish like this
static void Reflect(VECTOR IPoint, RAY *Ray, VECTOR Normal, VECTOR
Raw_Normal, COLOUR Colour, DBL Weight, FINISH *Finish)
however whenever I pass anything besides a NULL pointer as the finish
parameter when POV-Ray reaches the object, it crashes and displays a message
about an error reading memory. Any thoughts on why it is doing this? I've
never encountered a problem like this and any assistance would be greatly
appreciated.
Thanks

Hard to say anything without more info.

The only other thing is that every time the is a call to Reflect(...) it has
been replaced with Reflect(..., NULL) except in the case of Reflect(...,
Layer->Finish) in compute_lighted_texture()

That's still not enough to analyze what's wrong with your code.
If you've added one parameter to the Reflect() function, most
likely you also added some code IN the function itself to handle this
new parameter. This added code is what you've been asked for...

Recompile all the povray source code including your change.
That might help getting rid of the crash.

Tried that several times already. I'm pretty sure it has something to do
with Layer->Finish, because I've tried a few other things with it since and
it appears to be the source of my grief.

Based on the prototype for the Reflect function you included earlier,
is Layer->Finish a pointer
to Finish? Or is it a Finish structure? Not knowing how the Layer struct
is
defined (as I haven't looked at the source code ever), but considering the
error your are receiving, I would guess it is not a pointer, in which case
you should use Reflect(...,&(Layer->Finish)).
Otherwise, maybe you are not properly populating Layer->Finish.

It is a pointer, so I can rule that out. If it wasn't a point then when ever
I compiled vc would give me error messages which I'm not getting. and I know
it is populated properly because I'm using in the same funtion just a little
before and it works fine.
This is starting to look more and more like one of those inexplicable errors
that no one can solve :-P
