I've been playing with the Montespan room, and one of the walls is supposed to contain a mirror, but all I get in renders is black. Am I supposed to do something to it to make it reflective, and if so, what? if it's in the advanced part of the materials room can anyone who knows please use simple language as all the fancy jargon in it frightens the bejazus out of me. Thanks!

Assuming the material is set up to do reflection already, you don't need to go in there.
Probably what is happening is you forgot to enable raytracing or you have bounces = 0 - you need to enable raytracing and have at least one bounce.

Aha! thank you very much. I usually enable raytracing, but I cannot recollect what, if anything, I did about bounces. I flunked Physics....

YES YES YES! thank you very much!
I WILL get to grips with the technical stuff one day, but getting a result with that has made my day. Thanks Bagginsbill!

I also read on your page about using at least 6 bounces for glass for internal reflections [that part I did pass in Physics] so I shall be happily playing with glass now...

Well, show us a render now! :)

Gimme a chance... I need to unzip something made of glass now to play with! I'll have half an hour free time in the morning before I have to get mother up and feed her.

Ok, I'm a little disappointed with the glass, which isn't as transparent as I'd like it. this is the share CG freebie 'Green Vase' which is the only bit of glassware I currently have...

Hey, I got it, I managed to make it transparent in the advanced settings! It ain't anything to shout about, but the more I experiment the more I'll learn. I turned off the IBL as well.

It's lookin' pretty good, though. :) Maybe you could screenshot your render settings and the advanced material room setup for the vase - we could tweak it. I'd try giving it transparency falloff of 0.6 and set transparency edge to about 0.15
I have some wine bottles which would work well - just delete/hide the wine.
A jade tumblehome mug (delete the coffee/tea, and try to give it some light from behind to exploit subsurface scattering.
The silver (mithril?) ewer from Galdriel's mirror would look nice as glass.

Oh wow, thank you for those links, and for putting up such fun freestuff; and especially for the settings suggestions because I'm at the WTF?!!! stage with them.... I'll need to install the screenshot software on the computer I use for graphics, hadn't thought of it! I'm faffing around in the dark here, I'll have to print some pages of the manual out I guess! Can't assimilate information I read on screen, too old I suppose...

Reflections and refractions must be used (not transparency and specular) and they must obey the Fresnel equations. (Which you don't need to know - it's in the Fresnel_Blend node.)
On the left, the abomination as it loads without modification.
On the right, the way it should look.
I'm going away for the weekend so I'm not going to be able to post, but others should be able to help you find the dozens of threads I've written on this kind of material.

Wonderful! I do appreciate all the kind people who understand how this works who are ready to give tips
