i'm building a valve - it's a Mullard type QV05-25.
(photos of this valve)
what you see is the result of an evenings modelling (in blender), and (edit) rendered overnight.
i still need to model the rest of the innards - mostly metallic constructions.

a few questions though:

1. there is a circular disc within the valve that is supposed to be Mica i think. ( http://en.wikipedia.org/wiki/Mica ) it's transparent - but not as transparent as glass, and has kinda rough edges. how can i make this look more realistic?

2. the whole render looks kinda desaturated. the base is actually a brown bakelite colour in blender - but here it looks metallic. what gives?

and an observation:
the top cap is supposed to be metallic. i shall be making it lighter in the next session.

oh, one other thing - i will need to put the writing on the glass. i'm assuming i can do this with a standard texture map with alpha channel?
any advice here?

any other comments are welcomed.

cheers.

If it looks too metallic try sliding the spec down.

Nice start, looking good.

sorry, wrong choice of word - i meant metallic as in colour, grey... it should be brown.
i'm happy with the actual material properties.

You need to tun down the specularity on you bacolite material. The higher the spec, the less saturated your diffuse colour becomes. It doesn't just affect reflections. Try something around 0.2 if you still want it to look shiny.

ok... looking a bit better now. i'm resolving the materials issues:



just the modelling to finish then...

yeap looking good now!keep it up

thought you might be interested

your amp is what inspired me to do it.

if this goes well, i might build up a library of popular vales - 6L6, EL34, EL84, ECC83, KT66 etc and release them for people like yourself to use (that is, if you would want to).
I actually have a lot of these valves - it's certainly very helpful to look at the real object whem modelling!

thnx man....i have some tubes too..im electronic enginering and i have some just for collection!good luck with your work!
