V-Ray Final Setting
[ Part 2 / Read the first part: V-Ray Interior tutorial ]
It’s time to render. Until this step images usually comes with noise and splotches. It’s due to a test settings: these produce not perfect outcomes but really fast to render. Now, the goal of this step is to get clean images. For this I usually apply these four settings:
- Antialiasing: Progressive
- Brute Force + Light Cache
- Light Cache 1500 (as a security margin)
- Noise Threshold: 0,005 (0,008 shoud be fine as well)
90% of cases this works fine for stills and produce really clean images, Chaos Group also indicates these settings in some of its vray interior tutorials :-)
In the movie “Gravity – 3D” often objects pass near the camera, giving a strong depht sensation. The most obvious way to achieve the same feeling is using the deph-of-field (Dof)
Recreating Dof in V-Ray is really very simple if you know photographic concepts, because V-Ray just reproduce exactly the same conditions.
Basically Dof depends on 3 factors:
- Distance from the object;
- Focal Lenght;
- f aperture.
To understand how Dof works, check the LESSON#13 (in the 5SRW Course for V-Ray)
Post-Production (after V-Ray)
Below you can see the final result after the final render. Many people call this raw render:
It’s time to give it a mood :)
No Render Elements was used for post production. To create the “space station” mood I just used a simple and great tool recently added in Photoshop CC: “Camera Raw Filter” (if you are a photographer this should be very familiar to you!).
I strongly turned the image to cold colors, increased the contrast and whites, and finally closed a little bit the darkers. It’s enought to enhance the render, bringing it to the next level.
Finally, adding an human figure in a realistic way could seems very complicated, but also in this case it’s not true if you have the correct approach. You can’t believe how simple it is: just take your shot using the real light in the same way how the light is used in your render!
Original shot: directly light on the legs, diffuse light on chest and head ———–> Final Shot: everything correspond to our lighting (more or less)
I hope you liked this breakdown in 5 step, following the method “5-Step Render Workflow”.
Use V-Ray like a DSLR in your hands and get photorealistic results easily :-)
