VECTORTUTS has covered Illustrator's 3D effects a few times, so the nuts should already be familiar to you. In this tutorial, we'll be taking those skills up a notch and discussing how Illustrator deals with transparency in 3D objects. In but a few steps y'all'll have created a plastic cola canteen, which is ideally suited for those of you involved in production marketing.
Final Image Preview
This is what nosotros're looking to build with this tutorial.
Step 1
We need two symbols for mapping to our last 3D object; a canteen label and some texture for the screw top. Make yours with like proportions to those shown beneath and use whatever designs yous wish. Group the label components (Objects > Grouping) to make a label group and also group the top texture components.
One thing to bear in mind is the use of gradients within these symbols. Illustrator volition rasterize gradients when applying the symbols to 3D surfaces. This is fine and may well requite you the desired event, only in doing so y'all'll limit the scaleability of your final object.
Pace two
Open the symbols console (Window > Symbols) and drag each of the two groups into the window. Depending upon which version of Illustrator yous're using, you'll either be presented with the Symbol Options dialogue automatically, or you may have to double-click the symbols once they're in the panel.
Either way, enter a name for each of your two symbols within the Symbol Options dialogue and click OK. Y'all may also find it useful to display the Symbols panel as a list (as shown in the image beneath), which allows you to see the symbol icons plus their assigned names. Existing instances of the symbols on your artboard may now exist deleted.
Step iii
I'm now in Outline mode (Command + Y to switch between Preview and Outline) while working with simple vectors, only you lot can cull which view mode you prefer.
Utilize the diverse drawing tools to form the shapes needed for a silhouette of a cola canteen. Marshal them all centrally, but don't worry if the whole thing isn't perfectly symmetrical, nosotros're going to slice it down the middle anyway. There are many approaches to preparing shapes for revolving, this way gives you a reasonable impression of the concluding form before you applied the 3D outcome.
Step 4
Utilize the Pathfinder tools to join the shapes. Then aggrandize your shapes so yous then have i complete object.
Step 5
Depict a line vertically downwardly the center of your bottle object. So align the two together centrally. Now click the Pathfinder'due south Carve up tool and Aggrandize the result. Your object will have been split neatly in ii.
Ungroup the 2 halves (Objects > Ungroup) and delete i of them. It makes piffling divergence which of the ii halves you delete; more than on this after.
Step 6
Nosotros're going to continue splitting our object up, this time with a series of horizontal lines. What nosotros're aiming for is a collection of pieces so each area of the bottle can have information technology'due south ain color and transparency backdrop.
Start with a line to separate the bottle meridian from the balance, and then one which will begin the characterization, and another for the plastic underneath the characterization. Continue with this method until your design matches the image shown below.
Pace 7
Once more nosotros turn to our Pathfinder Tools. You lot've no need to group the horizontal lines together, simply select everything on the folio and click Divide. Expand your object as you've washed earlier. Then ungroup (Object > Ungroup) to release your canteen sections from each other.
Stride 8
Use the Direct Selection Tool to select iv of the nodes forth the border of your object (as highlighted below). Then press Delete to remove them. This should leave you with a segmented vector defining the outer edge of half of your bottle.
Step 9
If yous're currently working in Outline mode, switch to Preview (Command + Y) so we tin can determine some colors. Give each of the five canteen sections a color and exit the stroke width at it'south default of 1px (the stroke width volition effectively determine the thickness of your bottle's plastic, y'all may desire to play around with this).
Step 10
Select all your bottle sections and grouping them together (Object > Group). This is a simple but crucial phase in the 3D revolving procedure. We desire all the sections to exist treated as ane unit and for the furnishings to be applied to the grouping every bit a whole. Without grouping them, the revolve effect would exist applied to each department individually, creating five random 3D objects. Try it for yourself!
Step eleven
Select your now grouped canteen vectors. Get to Effect > 3D > Revolve and click Preview in the Options dialogue that appears. You'll be presented with a revolved 3D rendering of your vector, turned 360° effectually the left edge past default.
This brings u.s.a. dorsum to Step 5 when I mentioned "more on this later." Well afterwards is here now. When I split the whole canteen object into ii halves I chose to delete the right paw side, leaving me with the left. If y'all did the same, your bottle will have rendered as below.
You'll need to alter the settings so that the object is revolved effectually the right hand side, as shown in the second epitome below.
Step 12
Within the 3D Revolve Options dialogue click on Map Art, which opens the Mapping dialogue. Select the surfaces you need using the surface navigation arrows and map the appropriate symbols to them from the symbols dropdown. There volition be a lot of surfaces to choose from with a complex object like this, so information technology may take a while to find the ones you're afterwards. This is particularly true when revolving a vector, as surfaces on the inside of your object can likewise exist mapped.
Click Shade Artwork and then click on OK. Once dorsum in the 3D Options dialogue, play effectually with the bending, perspective, and lighting (under More than Options) until you're happy with the result. And so click OK.
Step thirteen
We now have a nice 3D canteen with a label and a bit of lid texture, simply the plastic and the cola is opaque; we need to resolve the issue of transparency (here comes the most important part of the tutorial). At that place are several ways in which you lot may think to approach this, then I'll outset cantankerous off the incorrect ways, and so demonstrate how it should be washed.
1. Past selecting the 3D bottle and reducing the opacity in the transparency console the whole object will fade. Furthermore, yous won't fifty-fifty be able to see the opposite side of the object, it volition have been treated equally a 2d image. This is because when Illustrator renders an object in 3D information technology offset flattens the transparency of that object (run across the first image below).
ii. Instead we could expand the group in the Layers panel or double click the object to reveal the group elements. By selecting only those we demand and altering their opacity we can give our bottle a transparent await (see the 2nd epitome beneath). The right approach! Correct? Wrong!
Step 14
Technically we've but accomplished the await we wanted, simply in terms of best practices this method isn't going to win a gilt star. Illustrator has flattened the transparency of the main object (in this instance the group of vectors) though now nosotros've contradistinct the properties of an object inside our group. This transparency isn't flattened and the consequence works.
All the same, imagine that we didn't have a group. Imagine instead that nosotros'd congenital a single vector to make a green drinking glass canteen and nosotros likewise wanted to apply a transparency. We wouldn't take a grouping to expand, yet we'd however demand to modify the transparency of an element within our vector, so this is where the third correct method comes into play.
3. Open your Appearance panel (Window > Appearance) and use the Directly Option tool to click on a vector whose transparency you wish to modify. In the Appearance panel yous tin at present isolate this object's stroke transparency properties. You lot do this by clicking on the Stroke aspect and changing the value in the transparency panel. You aren't altering the properties of the object, but the properties of it's stroke, which is every bit far downward the properties hierarchy equally possible! Guaranteed transparency!
Give the strokes of the plastic sections a Multiply Transparency of 40% and the stroke of the cola section a Multiply transparency of 60%.
Footstep 15
If you experience the bottle needs to be standing on something, make an ellipse, give information technology a radial slope from 50% black to white and scale it vertically, every bit in the image below. Position it underneath the base of the canteen. Make another (larger) ellipse, give it a radial gradient from twenty% black to white. Then Mask (Command + 7) the tiptop one-half with a rectangle. Position information technology behind the bottle equally a horizon.
Unfortunately, Illustrator doesn't (yet) cater for ambience such as dedicated 3D programs, so you'll have to imitation your own shadow.
Conclusion
There we take it! A transparent 3D plastic cola bottle! Indistinguishable your terminal bottle if you want to really demonstrate information technology's transparency. Scale information technology to let for distance. Bear in mind that when altering the scale of 3D rendered objects (or the stroke width, etc.) your image mapping may need to exist reapplied. Information technology's likely that your surfaces will have been assigned different numbers and that your symbols are attached in different places.
