SketchUp Render using Blender and Photoshop
by Jean-Pierre Hurel
Jean-Pierre Hurel (better known as Orgelf in the Internet design communities), a visual artist, explains his simple technique on how to achieve this render of a SketchUp model he made by using Blender and Photoshop . It produces what has been described as a cartoon/comic book effect.
.
To produce the final image below you will need two renders from Blender, that you will then mix in Photoshop.
Final Image
The two output renders in this tutorial are:
1. Ambiant Occulsion Render
a. In the Material panel (1), Create a new material (2), Name it “White” (3). Choose a pure white color (R=255,G=255,B=255) (4) and set the Diffuse at 100 (5).
Settings 1 and 2
Settings 3 to 5
b. In the World panel (6), Tick the box to activate Ambiant Occlusion(7) and enter the parameters as shown in the image below (red rectangle).
Settings 6 and 7
c. Now place your camera and render at 1600 pixels wide (press F12 to render). Save your image.

2. Edges Render
a. First we will set the scene. Turn off any light source and the Ambient Occlusion. In the Material panel, select your material “White” and check “Shadeless” (8).
Settings 8
b. In the World panel choose a pure white color (Horizon Color) (9), the same as that of the material.
Settings 9
c. We will now create the “Edges”. In the Render panel under the “Post processing” section, make sure to check the “Edge” box (10) and set the cursor “Threshold” to the maximum 255 ( 11 ). This slider sets the importance of the number of edges when post processing.
Settings 10 and 11
d. Make a render of 6400 pixels wide (we can reduce the size in Photoshop) for this image to give us fine lines and and save it. You can render the image at a smaller size if you don’t mind thicker lines. The problem with “Edge” is that the line width is not configurable in Blender. Therefore a line that is 3 pixels wide will be 3 pixels wide. If you want fine lines you need to render at a huge size but that will increase render time dramatically and probably crash the software.

3. Final Post Processing in Photoshop
a. Open both images in Photoshop. Make sure the “Edge” image is the same size as the “Ambient Occlusion” image and place it on top of the “Ambient Occlusion”. Set the Blending mode to “Multiply”.
Set Blend Mode to Multiply
c. If the “Edges” are not dark enough for you in the final image, nothing prevents you from duplicating the “Edge” layer in Photoshop.
