transparency

[Fouad B.]

Think one day that we will have a shader glass with refraction and transparency ? (without playing with flatten layer) bus at present, except matter on the refraction, the transparency have criteria which escape to me. Note the two bottles which overlap that of the bottom does not appear through the first.

Hi Fouad
The key of transparency is put each object on a different layers !
Rendering transparency can play at this only condition !
Hope this help!
Pilou
Ps Quicklinks + transparency in the window research of Navigator will give some advices :)
Some tuts indeed :)
This of Pixolator is always the best :)
I believe that is inside the prog :)

And this one super cool ! (http://www.pixolator.com/zbc-bin/ultimatebb.cgi?ubb=get_topic&f=1&t=001234)

Hi Fouad I like this tip is very practically¡¡
Thanks for share¡¡

thx Pilou and André.

Pilou, I'm right .. and saw these tuto about transparency, but all seems some "do-it-yourselfing" not really transparency.

in fact, I am astonished to see that glass is still not treated correctly in Zbrush, knowing that we have tools extraordinary and that on the level of the shaders the Pixologic team with already done a work of more successful, we have shader indeed allowing to create all and anything, only... glass is the poor relation of the software. Another thing, the tool Sweep, very powerful lack a little ergonomics I find the Zoom in the graphs of adjustments (and it is valid for all the curves of reglages) is an excellent idea but difficult to manage the double clic for Zooming adds sometimes by accident a point and it misses the possibility of scroll in zoom mode on the curve.

Hi Fouad B in the meantime this ZGlass Cameyo script will help our eyes looking for the tip of the curve in the sweep tool¡¡¡hehe

Hi Fouad
And this thread (http://www.pixolator.com/zbc-bin/ultimatebb.cgi?ubb=get_topic&f=1&t=012782&p=)? (2 eme page script by Alan) seems very good !
Yes the window of the sweep profile is a little little :D

[Fouad B.]

double clic on it (window sweep profile) and you will have a zoom Pilou.
I saw this script.. but.. not really transparence or refraction.
only some manipulation to simulate.

Hi Fouad
Yes but the Zoom window is also a little little ;) (for me :)

For your transparency and without put rgb to small value

I think that the solution is realy a layer by object
Here just 2 layers cube and the little green sphere big spheres on another one
2 Objects on the same layers seems don't intesected (big spheres)
The little green sphere has a material transparent but on the last layer as the cube so not transparente!
And without flatten layers I don't see how resolver that !
For just an object = a layer :)
But I have no time to test it !
So long!

Yes Pilou I know that... but..

but you are obliged to work with layers to exploit the transparency, during my compositions I work already with much layers and I am often limited, with the transparency you are obliged, moreover, to juggle constament with handling often unpleasing and not very convivial. As you can see it on the image below the bottle was added on a different layer but that does not solve of it the problem of the bottom of bottle which does not appear in transparency. The transparency is not allowed to manage at the same time the effects such as shade "Zmode" fog etc. Too bad.

I have to try post the pic on the other topic in order not to reveal the image on the zone of preview, and it appears!!. arff I have failure a trick.
