Hi all, thanks to the CGarchitect team for this great site and thank you for all who give comments, feedback and encouragement. In this article I will try to write the Making Of Siek Box House. This is my work for challenge the facebook group “3D Render Party”, and this box house is the 5th season of this group's challenges. The building model was provided by Arya Siek (the organizer/administrator of this group/challenge).
CONCEPT AND WORKFLOW
I believe that the preparation and planning step is very important in every visualization project. I was imagining which environment would be good for this box house. I had a simple picture in my mind about a silent river beside the house, with many stones on the river. I used Linear Workflow for gamma setting in my scene, and I turned the gamma to 2.2.
As I mentioned before, this model was provided by the organizer of this challenge. But I remodeled this whole part of the house because I wanted to put some details with chamfered edges on every corner edge. I believe in reality most of the corner edges around us are chamfered, not sharp like a knife. I also made some details like screw heads on the railing.
Most of the textures that needed dirt, like the concrete wall, the window frame, railing, back-wall panel, pool andconcrete, used the VrayBlendMaterial. I used VRayDirt for the 1st and 2nd blend amount. But you have to swap occluded color and unoccluded color in it. One of the V-Ray dirt is normal, and the other one is invert normal, to put the dirt on both directions of corner (inside and outside). The last blend amount is for the leaking part at the bottom of the wall, I used a leaking texture from www.cgtextures.com. Many of textures in this scene came from there. Here are my material setting for concrete wall:
I needed to put different map channels for the dirt, so here are my UV mapping for the wall:
I used the same method for the railings, pool concrete, window frame and back panels textures.
Here is the ground material where I applied the VrayDisplacement modifier:
Next, we have to define the environment background and GI. I used two slots for the material, one of them for the background, and one for lighting (GI). Both were made the same, but just in case I needed to make some changes, I made them in separate slots. For the environment background and GI, I used a mix of material between VraySky and Bitmap. The bitmap is a 360° sky bitmap that I downloaded from www.cgtextures.com, I choose the dusk one. I did many tests for this to define the mix amount (which one is better, close to the VraySky or close to the bitmap sky). In the bitmap, I also brought the RGB levels up to get the right level. Here is the mix:
GRASS, PLANTS AND SCATTERING
I used models from iTree and Evermotion for the trees in this scene and of course I proxied them. For the grass I used models from iGrass, and then I scattered them using multiscatter and multipainter. I also painted some gravel on the ground. Here you can see the scatters I used:
Gravel (I used the asteroid generator script to create many different shapes of stones):
I rendered this scene with V-Ray, my favorite render engine. Here are the render settings:
In this post-production step, I used Photoshop and MagicBullet PhotoLooks. Actually this is not a heavy post production. I only did color corrections, added contrast, glow and fixed the saturation on grass. Here are the layer/steps:
Darker water and stones
Color correction and add contrast
Color correction and sharpening
More sharpening on the gravel and stones area
Reduce grass saturation
More contrast and sharpening on the left/foreground tree
Adding sky glow
Adding a little bit fog using Z-depth
Add darker part at the bottom of the stones:
As you can see, the post production for this scene is not complicated, it is only about adding contrast, color correction, and adding fog and glow. But the most important thing is to think creatively when we compose the image.
Here are the wireframes for every single view that I posted before:
Well, I hope you enjoyed this article, and may it help you in some way. Please feel free to ask if there are any questions.
