Hi Kosmo,
could you please post your tests about the rendering with hot tubes, this would be really interesting
(perhaps in work in Progress)
And also how you modelised the tube.
I suppose the sucsess of such a rendering (in my opinion) is the quality of the model, because indigo is so perfect.
So I think we must create better model (more precise and more detailed).
And your scene is right know really detailed (I mean the amplifier)
This really a lot of work
(But perhaps it will be sufficient to see a test with one tube)
And finally, I like this picture.
It remembers me on another picture here in the indigo gallery with a lamp which was also incredible realistic, but I can not find thie link (sorry).
regards, Phil
