Step 8: Exporting from SketchUp to Painter
Goal : Export a line drawing from SketchUp to Painter.
Input : My 3D model.
Tool : SketchUp.
I eventually choose camera 2 as my favored viewing angle, and export my
scene as a 2D image. I export the image as a .tiff file, which seems to be the
most reliable uncompressed image format to use from SketchUp, at a resolu-
tion of 4000 × 2700 pixels.
In Painter, I copy this image into a new layer, and set it to the “multiply” blend
mode. I then clear the canvas layer beneath it.
Anything I paint on the canvas will now sit “below” the exported image, allow-
ing me to be quite rough with my brush strokes.

Step 9: Laying Down Rough Colors
Goal : To lay down the “underpainting” as a rough color wash.
Input : My original rough sketch.
Tool : Painter.
Using a large digital watercolor brush, I lay down rough areas of color. This
is the digital equivalent of the “ink wash” technique I used when painting
traditionally. Initially, I use the Eyedropper tool to pick color from my original
sketch in order to capture some of the “feeling” and “atmosphere” that I like
about it. I then block out the major forms of the boat using a square chalk
brush.
