AutomotiveConcept Development Rendering

Post  Admin on Fri Jun 05, 2009 6:12 pm



The goal for this project was to produce a fairly detailed sketch render of an open-wheel, mid engine sports car with deadly accurate perspective.

Instead of spending hours trying to work freehand lines into perfection I decide to throw together a quick concept model so that I could create an underlay for the final image.



I begin by laying out orthographic sketches of the initial design intent. (Profile view came first, followed by top, and finishing with the front end.) Once compiled, I start laying out basic curves and planes to get a basis for the concept model.



Once I’m content with the level of modeling for the purpose of the exercise, I turn on hardware shade with a few tweaks to enhance the highlights and shadows. For this image, I’m also looking for a reflection and a hard shadow to the passenger side of the vehicle.



Now I’ve found my positioning and decide to open the doors to create a more dynamic and aggressive stance. (The background colour has changed as I’ve switched from Modeling workflow to Paint workflow.) Here I could begin sketching onto a new overlay canvas. This allows you to draw on the canvas within the same file as the model at a specific bookmark. I prefer to take a screen capture and start a new Paint file, importing the capture as my base layer.



I add a new layer over the capture and flood fill with White. After pulling down the opacity so that I can see the sketch beneath, I add a new layer to begin the sketch. This is where I could start using the lines of the model to snap my pencil to, had I been using an overlay canvas.) However, I use freehand lines and predictive strokes to get the initial line drawing out. I’ve built up the door panels and interior as I didn’t get around to modeling it before the sketch. I also added a small insect-like headlamp to the front end. This is a process of creating layer after layer to avoid erasing or drawing over completed line work. Once the sketch is completed, I merged all the layers, except for the bottom two.



Now that the main sketch and reflection sketch are completed (on separate layers.)I add a new layer between the white and the two sketch layers. Here, I am trying to build up a pearl white base with a satin finish. So I first throw down a light tan airbrush stroke heavily on the lower edges of the body.



On another layer, more dark tones are added with the airbrush and any excess is erased using a hard eraser. This is the basic idea for all the painting operations.



A slight hard edge of the tan is added to attain a slight shine without having an overly glossy feel to the nose of the car. A quick sketch is drawn over the model’s heavy shadow. A layer is added below, and Airbrushed with a hard black. The lines of the sketch are used to erase the paint back to the confines of the shadow. The sketch layer is turned off and the shadow is tweaked with a Soft eraser and layer opacity. In this case, I duplicated the shadow layer and worked both layers to get the desired effect (most notably at the front “horns” of the underbody.) A quick stroke is added to a new layer below the sketch to start building up the reflection.



Now I begin with the detail work by painting the brakes and the horns. The brakes are built up of several layers: slate blue, darks, highlights, black circles for drilled rotors, and highlights for those holes. Once all the paint layers are created, they are merged to speed up the erase back process.



The decision was made to paint the horns a glossy gold.



Similar workflows are used to paint the centre hubs of the wheels. The paint is built up for both the main focus and the reflection. Suspension components and headlamp and test interior upholstery (in the reflection) have also been painted.



Now it’s time to punch up the contrast by painting the tires. They are simply filled with black and softened up with a soft eraser. A new layer is added on top to add the hint of a tread pattern. As I’m not looking for a perfectly finished photo real render, I spend little time on this by throwing down a custom texture brush based on a felt tip pen. (Lighter stokes on the bottom and darker on the top.) These, again are softened. Shading and reflections are added to the rims as well.



The interior is built up over 15 or so layers, and then merged. The same texture brush used on the tires is used to create a stitching effect on the seats and door panels. Three layers are dedicated to this alone: tan, darker brown below, and a lighter tan above all.




Now that the reflection paint is completed and merged, it can be toned down with a large soft erase and layer opacity. The main sketches are also altered at this point by fading out using the same process.



Now I take any design development from the sketch to the concept model and add them for later use. Headlamps and taillights were added at this time.
