In this Architectural Visualization workflow overview you will learn how to use GoogleSketchup for photo matching, create a Vray-proxy in 3ds Max, use Max script to speedup your workflow, reduce render times when creating a large scene, set render layers in3ds Max, and do some post production in Digital Fusion.

Step 1

Start Google Sketchup 7.1 (sketchup 6.0 at least), go to (File > Import). Use use asnew matched photo as the import option. This will help you quickly step intoPhotoMatch, Sketchups new function.

Step 2

Spacing = 1000 mm, meaning 1 meter per grid unit when the Grid option is set toOn.

Step 3

The Red and Green axis stands for the two vanishing points of the original photo, andthe Yellow line should be matched by the photos horizon line. These points should bematched the photos V.P as correctly as possible.


6/77

Step 4

Go to (Draw > Rectangle) to create a rectangle based on the original photosperspective, and then use the Push tool to generate a cube.


7/77

Step 5

Right click the top line, and chose Divide, then use the Line tool to create lines.Divide the cube by 17x19x5 segments.


8/77

Step 6

Use the same method to create a new cube on top of the original one. All of the

segments should be created based on the original photo.


9/77

Step 7

Use the Circle, Push, and Offset tools to create a column. Copy it by pressing N(N=1,2,3).


10/77

Step 8

This is the final result of the Sketchup modeling portion.

Step 46

Select a new material ball, change the material type to VrayBlendMtl, and select White

Plastic as the base material and Black Plastic as the Coat material. Make sure the UseInterpolation option is on. For the Blend Amount option, use a black/white jpg as amask, where the white part will be the Base material, and the black part will be the Coatmaterial.


52/77

Step 47


53/77

Select all of the window frames and apply the VrayblendMtl material to them.

Step 48

Select a new material ball, change the material type to VrayMtl, and set the diffusecolor to (219,203,180). Set the Reflection Color to (168,168,168), and make sure theUse Interpolation option is on. Select all of the interior walls, and apply it. Click to seethe larger image.


54/77

Step 49

This is the final result of the material part.


55/77


56/77

Step 50

Now to plant some trees. Here I use Evermotions product. You can buy and download

it fromhttp://www.evermotion.org/modelshop/show_product/sassafras-plant-24-am61/933/0/0/It has a lot of polygons on this tree, but it looks amazing to me, so I usedit to detail this scene. 40EUR per models may be a little pricey for your taste, butanyway you can find any tree models to finish the scene.
http://www.evermotion.org/modelshop/show_product/sassafras-plant-24-am61/933/0/0/http://www.evermotion.org/modelshop/show_product/sassafras-plant-24-am61/933/0/0/http://www.evermotion.org/modelshop/show_product/sassafras-plant-24-am61/933/0/0/http://www.evermotion.org/modelshop/show_product/sassafras-plant-24-am61/933/0/0/http://www.evermotion.org/modelshop/show_product/sassafras-plant-24-am61/933/0/0/http://www.evermotion.org/modelshop/show_product/sassafras-plant-24-am61/933/0/0/


57/77

Step 51

Select all objects that make up the tree, and go to (UtilitiesPanel > Collapse > CollapseSelected) to convert them into a single object.

Step 52Right click > Vray Mesh Export.


58/77

Step 53

Select a Folder to store the .vrmesh file, and make sure the Automatically CreateProxies option is on.


59/77

Step 54

Set the Display mode to Preview From File. 3ds Max just created a proxyautomatically.


60/77

Step 55Use the Instance Copy and Scale tools to duplicate the proxy in front of the building.


61/77

Step 56

This is the final result of adding trees.


62/77


63/77

Step 57

Create a plane VrayLight, and set the color to (249,132,74). Set the Invisible option to

off, change the Multiplier to 70, and Instance Copy this VrayLight to fit all of theceiling lights. Click to see the larger image.

Step 58Go to (Render panel > Vray panel > Global switches), and you will see that it is at draftrender settings.


64/77


65/77

Step 59

Open the Indiect Illumination panel and hit render (467700). My render time is around

57 seconds (ASUS C90P Notebook,cpu:Q9550, ram:4G, GC:9600MGT).

Step 60


66/77

Go to (Create panel > Lights > Free Ligh) to create a photometric light using an IES file.Move the photometric light under the Vraylight, and Instance duplicate. Here I have 114IES lights in this scene.

Step 61

Here is the result of adding photometric lights. The render time is 1 min at 467 x 700.


67/77


68/77

Step 62

Create another VrayLight, set the color to (255,163,82), and make sure the Invisible

option is off. This means the light can be seen by the renderer.

Step 63

Instance duplicate the light to the interior corridor (match the photos position ascorrectly as you can). Use the Scale tool to get light to fit the interior walls.


69/77


70/77

Step 64

Go to (Render Setup > Vray:Envirorment), and set the GI multiplier to 1.0. Use theFine.jpg to generate GI. Use a jpg to generate the reflection and refraction, with themultiplier set to 2.0 to give brighter reflections. Notice that the mapping is set to

Spherical.

Step 65

Here is a test render done at sStep 64. The render time is up to 5 min because of theVrayLight subdivs are set to 14 with 144 VrayLights. You can reduce the subdiv value tospeed up the render time. From this test render, you can see that the interior was a littlebit dark.


71/77


72/77

Step 66

Create a big Vray Plane light. Set the color to (255,188,82), with the Invisible option

on, but the Affect Spec and Reflections off.

Step 67

These are the final render settings in the render setup panel (click for the large version!)


73/77

Step 68

And the final render layers settings and render results (again, click to see the largeversion!)


74/77

Step 69

Now for the final compositing step we will use the software Digital Fusion 5.3.


75/77

Step 70

Drag the final exr file into fusion, and rename it as BeautyPass. Go to the Importpanel, change the depth to Float32, and set Post -Multiply by alpha to On. Whenyou save the .exr file in 3ds Max, Vray also puts every pass to a single file, so you can

change every render pass easily. Here are two examples (Diffuse and reflection pass).Click the Format panel, and change the RGB channels the way you want it to be.When you are done with a pass, use Ctrl+C to copy, and Ctrl+V to paste another node.Then go to the Format panel to change the channels. You should have a Diffuse,Raw_GI, Raw_LT, Reflection, Refraction, Specular, Sell_Ill, and Beauty pass. Click tosee the large version of this image!


76/77

Step 71

Here is the final result (click to see the large version!) Thanks for watching. If you haveany questions or suggestions, please let me know. Hope you liked this tutorial. EnjoY!!
