2D Rendering using AliasStudio 2009 Part 1 & 2

A Tutorial of how to render using Alias Studio by an Indian Industrial Designer.

With a series of posts I will demonstrate a procedure for preparing motor bike renderings in AliasStudio. I will upload the source file at the end which can be opened using AliasStudio 2009. Perhaps his is not a tutorial, it is just the way that I like to work when it comes to presentation renderings. Presentation renderings are prepared for the few selected concepts when we want to present it to the management, and it should convey the message clearly that, how will the bike look if a particular concept is going into production.

Here for the demonstration I will render the new Honda Fireblade using some reference photographs. First try to get a sufficiently large layout image and import it into AliasStudio.

The Layout had a studio background which I removed in Photoshop. A layout is very helpful to stay in proportion and sometimes gives us an idea of the volume the panels have to cover when it goes around the inner parts and unlike automotive renderings, we have to deal with a lot of machinery which is part of the bike’s looks.

And then using reference photographs, trace a sketch on a new layer! I keep the lines as clean and well defined as possible; this is to avoid confusion later on as we have to trace it using CV curves.

The sketch is reasonably clean, we can trace it to make masks. Before that I shall introduce masks and how it works in AliasStudio.

Part 2
Masks are very useful while rendering and will help you to save a lot of time and the work tends to be cleaner and well defined. The behaviour (i.e. what they do.) is very similar to masks in photoshop but setting them up and usage is a bit different.

Consider the following sketch, which we are going to render it in grey-scale using masks.

Now the sketch is traced along its boundary and main features. I usually use CV curves for this purpose.

Once it is traced with cv curves, we can create masks. Notice that, the masks created will appear below the normal image layers in canvas layers window. Now select and hold Palette>Paint>Shape then from the popup sub-menu select the mask shape option.

Now select the boundary first and create a mask for the boundary.

Now try creating a mask as shown in the following image by selecting a combination of curves. Create as many masks as you require by selecting any area enclosed by the curves you created. Note that, masks can be inverted also; by inverting the mask in the following image you can protect that area.

All masks are in place; now how to use them..

Unlike photoshop and lots of other image editing applications, where mask is a property of a layer (yes, you can unlink a layermask and relink it to another in photoshop but still that’s the idea, its kind of one per layer and more towards single layer oriented); in AliasStudio you can link any mask to any layer, any number of them together.

So create a new layer, make sure it is selected, and click on the link button corresponding to any mask (it is a small square on the right hand side of any mask, appears just before its preview). Now the mask is associated with the layer. Whenever the layer is selected the masks associated with it are highlighted in pale blue colour. Make sure the mask is active, a little tick mark on the left side of it. Now you can try painting on to that layer.

In the image below you can see that, I have filled certain areas of the sketch with various shades of Grey.

Then I would block different areas when I’m working and use large brushstrokes to bring about the form on to the canvas using 2 or 3 layers.
