This document summarizes the process of rendering an architectural model of Iwasa House using Vray and Sketchup. It describes: (1) Choosing the camera angle to focus on, (2) Setting up ambient lighting and HDRI to establish mood, (3) Texturing the walls, floors, and stairs by remodeling for realism, (4) Positioning IES lights, (5) Adding trees and accessories, (6) Setting render options and doing a raw render, (7) Applying post-production in Photoshop. The full process is explained over several sections to achieve a realistic final rendered image of the house.

2. Hai all .. thanks again to all for the support, also for SVA for choosing me as one of Iwasa challenge
finalist, but all the participant is truly the winner .. In this time, nothing special with the render
settings, its all actually the same concept like my previous tutorial, but i will try explain the method
how i doing from the begining.
A. Learning the model
When i download this model from the link given by SVA, i opened, and then i confused, because
almost all of the sides is very beautiful camera angle. Its very various and huge building. Trying
from the stair, but its too dark, i tried another from upper balcony, but need a vocal point to
shown whats the special of Iwasa House. Ahaa.. i choose from the downstair .. like the original
photo, its nice i think .. Actually, why i am telling you this phase? Because, for me, choosing the
camera angle is important, about 75% sense of the scene is depend on how we take the angle
shot.
Here is my view angle, so i will focus on this view only.
Make sure you adjust the angle especially the vertical line is exactly straight. This model can be
downloaded on SVA website or on the 3dwarehouse site.

3. B. Preparing the Ambience
If you notice from the original model, this scene dominantly consist with concrete material. And I
dont want to change it because Iwasa House is has this special concrete type. Then, testing
render for the first time, like this:

4. Usually, for the first step of work, i set out the lighting (ambience). Why? because the scene is
not to heavy to testing render to get a better ambience mood. Thats why i didnt touch the
material until I got the scene mood.
This time, i use HDRI. Here is the preview of the HDRI i am using.
And here is the setting on the render option
And here is the test render with HDRI applied:

5. C. Setting out the Texturing
Now, after i get the "afternoon mood" in my scene, now I learning the texturing.
The Wall
I didnt change the setting out point from the original scene because its already correct. I just
create a new bitmap for the texture of the wall. Here is the map i used :

6. and here is the material setting

7. And here is the preview render with concrete wall material applied.
The arrow on the image is the points that i dont satisfied with the material setting. Although i
already set the bump, but still need more deep on these part. So? i re-model the wall, so the gap
and the holes is really based on the texture i used. Here is the scene after i re-model the wall
(including re-model the stair and the floor).
So, you can noticed that almost all the wall, floor and the stair is re-modelled, and here is the full
preview of the scene.

8. I know this is not the best way by re-modelling, but, for me, to get the exactly to match to the
reality, i am realy satisfied .. you can check here is the render test..

9. The Floor
For the floor, the map i used is :

10. And here is the material setting for the floor

12. D. Lighting
I use IES light in this scene, the position is like the image below
Each of those light using this setting

13. E. Adding environment
Adding some trees and accessories to avoid the scene from "emptiness" .. ^_^
F. Render
Until all done, now is setting the render option. I use simple setting like the following images

18. And here it RAW Render
G. Post Production
I use some tools on photoshop, like :
- Exposure
- Color Balance
- Brightness contrast
- Magic Bullet Photolooks
- Knoll light to make the lens effect on the downlight
I am not explaining this part, because this is the same like my previous tutorial " THE MAKING OF
ATIKAH LIVING ROOM INTERIOR" you can find on this SVA website. ^_^

19. And here is the final result
