You'll have to forgive me if this is an old bug or it's my own fault, but
I've simplified my code as much as I can and looked it over, and I can't
figure out what the problem with it is. A quick explanation is that there's
an object inside another object, they both have the same IOR and the inside
object is transparent, yet it causes strange black internal reflection on
the outside object.

I made the scene just about as short and simple as I could.

The scene is commented, so if you read through the comments you should be
able to figure out what's wrong.

Again, sorry if it's just a problem with the code, or if it's a bug that's
not new to v3.5. Hopefully you can figure it out or set me straight.

The source is attached.

Try adding:

global_settings { max_trace_level 8 }

-- 
#macro N(D,I)#if(I<6)cylinder{M()#local D[I]=div(D[I],104);M().5,2pigment{
rgb M()}}N(D,(D[I]>99?I:I+1))#end#end#macro M()<mod(D[I],13)-6,mod(div(D[I
],13),8)-3,10>#end blob{N(array[6]{11117333955,
7382340,3358,3900569407,970,4254934330},0)}//                     - Warp -

Raise your hand if you feel like an idiot!

Heh... should have thought of that, thanks. =)

If I come up with something else, hopefully an actual bug, I'll tell you...
=)
