The making of OLD TOWN . . .

SketchUp – model set-up and test render
a. First I would like to show you the set of Components in this model with the Camera position.

Model Setup and Camera
b. Here is the whole scenario with copied model Components and reflected Sun Shadows.

Complete Scene with Components and Shadows
c. Just a rough test render with Override Materials selected (Global Switches), except the glass windows.

Tips and Tricks – Option Editor Settings
1. Tip to avoid crashing your rendering if the scene is to ‘heavy’. Change the Dynamic Memory Limit from default setting .

Change the Dynamic Memory Limit
2. To remove the splotches in the scene, adjust the noise threshold from .01 to .002.

Remove the Splotches in the Scene
Sun Settings
Open SketchUp Option Editor and use the following settings.

Sun Settings
Day Scenario
Hide the Omni and Emissive Lights.

Day Scenario
Option Editor Settings – Test Render
I always do a test render just to check if my global illumination and shadows are OK.

Test Render
Day scene render with adjusted color corrections.

Adjusted Color Corrections
Day scene render – raw PNG image.

Night Render - Option Editor Settings
HDRI Settings

HDRI Settings
Night scene render with adjusted color corrections.

Adjusted Color Corrections
Night scene render – raw PNG image.

Raw Render
Photoshop – Post Processing
a. Open the raw image output or the adjusted color correction image from SketchUp render output.

Open Image in Photoshop
b. Adjust Brightness and Contrast (Image>Adjustments>Brightness/Contrast).

Adjust Brightness/ Contrast
c. Add background image to the scene.

Add Background to Scene
d. Put  the Background Layer below the render image Layer.

Background Image Placed Below Render Image
e. Duplicate Background Layer. Turn off the original Background Layer. With the duplicated Background Layer active, remove the sky using Lasso Tool. We want to achieve a nice dusky/night sky for the nightime render.

Remove Sky
f. Choose a suitable sky for the night scene. Place it below the duplicated Background Layer so it shows behind the mountains.

Place Sky Below Duplicated Background Layer
g. Select your duplicated Layer again (mountains) and adjust the Brightness/Contrast (Image>Adjustments>Brightness/Contrast).

Select Brightness/Contrast
h. I Used these settings for Brightness/Contrast. Brightness -100 and Contrast 50.

Settings
i. Add some effects to the water now. With all the other Layers turned off, except the duplicated Background Layer which is active (mountain), using the Lasso Tool select an area similar to the red outline area in image below. Add a Feather Radius (Select>Modify>Feather) to your selection (to soften it). I chose a Feather Radius of 50. Copy and Paste this selection over your duplicated background Layer (mountains Layer) we have been working on.

Water Selection
j. Again adjust Brightness/Contrast for this new pasted water Layer, Brightness 30 and Contrast 20.

Water Brightness/Contrast
Light Effects
a. Now I am going to add some volume light effects to all the white lights. First we create a new Layer first and place it at the top of the Layer stack.

Create New Layer
b. Next locate the rendered image in the Layer stack, should be second now in the Layers. Using the Magic Wand Tool, select all the white bulbs.

Select White Lights
c. Fill your new Layer with White.

Fill Layer With White
d. Duplicate White Layer.

Duplicate White Layer
e. We have two white filled Layers now. Locate the top white filled Layer so its active.

Select Top White Layer
f. We are going to add some Gaussian Blur too this Layer (Filter>Blur>Gaussian Blur). Set the Radius to about 10.

Gaussian Blur Filter
g. Now duplicate this Gaussian Blur Layer. You can now see the effect it creates around the white light bulbs.

Duplicate Layer
h. The more you duplicate this Layer the greater the effect.

Duplicate Layer for Greater Effect
Entourage
Finally I add some PNG people on a new Layer to complete the image.

Add Entourage
Final Night Scene Image

Final Day Scene Image

Day Scene
NPR – FotoSketcher
I am using the final night scene image for the NPR. Open it in FotoSketcher and use the following settings:
  • Drawing Style – Pencil Sketch 5
  • Edge threshold 0
  • Edge intensity 180
  • Blending intensity 50
  • Darken/Lighten 140
  • Color intensity 200
  • Texture – Strong Texture

Featured Visualizer: Zernan Suarez
Some of us can still recognize these excellent images done in Vray SketchUp. Who could believe that most of these works were done with the old VraySU 1.05.33.Well, the man behind them is Zernan Suarez, aka "Zdesign". Zernan is one of the famous visualizer at http://www.cgpinoy.org/ using Google SketchUp and VraySU. I myself is a fan and  follower of  this man. I love the way he creates his scene with dramatic lighting. Zernan's is also a generous and regular contributor of excellent tutorials when it comes to visualization.

If you remember, this vray for sketchup rendered image is one of my entry in September 2010 Chaos Group Vray Render Contest and it's included in one of the pages of CatchUp – SketchUcation Community News – Edition 1
Thank you very much to sketchucation and the Daily Catchup
