Different ways to add Gamma in your renders Share with your friends! Every real device to take pictures adds gamma. We actually are “producers” of images and we need to correctly setup the gamma in 3ds Max, in order to imitate the behavior of real cameras. In 3ds Max the options we have to add gamma are various: Gamma in “output” / preferencesGamma / color mappingDon’t Affect colors / color mappingsRGB button /V-Ray Frame Buffer (VFB) Every option in this list affects gamma. I’m going to show you how many combinations are possible and you’ll see just one way is the correct one. COMBINATION 1 : Gamma in.. - Gamma in “output” / preferences = 2,2 - Gamma in color mapping = 1,0 - Gamma in VFB (sRGB button) = disabled Brief Explaination: You’re adding 2,2 to the final image. COMBINATION 2: Gamma in… sRGB button (follow the green arrow) - Gamma in “output” / preferences = 1,0 - Gamma in VFB (sRGB button) = enabled Brief Explaination: You’re adding 2,2 with the sRGB button but it’s just a “preview” of gamma. COMBINATION 3: Gamma in..
CAVE | Database: Database of Contaminants' Patterns Textures or patterns of the contaminants play an important role for photorealistically reproducing the effects. We model the patterns as 2D optical thickness texture, τ(x,y). To measure τ(x,y), we use the shadow map generated by attenuation from the contaminant layer. The following image shows our setup. Copyright The database is the property of Columbia University. Download The database contains 36 samples, including various kinds of contaminations, such as dust, dirt, fingerprints, lipids, soap water deposit, oily smudges, clay, and so on.

Vray rollouts explained - free V-ray 2.0 tutorial | Aversis Caustics are light patterns formed by refracted/reflected light. Take a look at the rendered image, these are caustics. There are two types of caustics: GI caustics and direct light caustics. In the GI rollout, you may have noticed two check-boxes: reflected and refracted GI caustics. Also, if you have for example a max omni or directional light in your scene, they will not generate caustics as it is not GI light. But, if you want caustics from max lights, or very sharp detailed caustics, you have to enable the Vray direct light caustics (also called photon mapped caustics). For now, just remember that there are GI and direct light caustics, reflected and refracted caustics, and that if you want GI light to pass transparent objects, you must enable refractive GI caustics.
Compositing V-ray Render Layers in Photoshop In this tutorial Ahmed Fathi takes a look at how to composite together V-ray render layers using blending-modes and masks in Photoshop. Once completed, this process allows you to change or tweak any aspect of your image in seconds without having to re-render a thing! Ahmed also covers a few extra post production techniques such as Chromatic Aberration and Depth Of Field, as well as how to emulate a Cross-processed look. Republished Tutorial Every few weeks, we revisit some of our reader's favorite posts from throughout the history of the site. This tutorial was first published in July of 2010. Additional Files/ Plugins:Download the Project Files for this tutorial Step 1 As this is a compositing tutorial, not a lighting/rendering tutorial, I'll assume that you have at least a basic knowledge of V-ray, and that you are able to render out your own scenes already. Step 2 We'll start with the VRayZDepth element. Step 3 Step 4 Step 5 Step 6 Step 7 Step 8 Step 9 Step 10 Step 11 Step 12 Step 13 Step 14 Step 15
Exponential and linear colour mapping in Vray Within Vray there are various processes and tools that we use to generate what we would consider to be a realistic rendered image. Options such as tone mapping, light intensity and camera exposure are fully configurable and can be moulded into what a 3D visualiser would name as their workflow. There are no right or wrong processes as they all lead to the same goal, to produce a high quality render. If you choose not to use a linear workflow, it may not be physically correct in terms of light intensity but it might look correct and is therefore acceptable. Blown out lights are caused by the camera settings. Vray renders through a camera and that is why in a linear workflow you will see blown out lights. There are other colour mapping types available such as exponential that help eliminate blown out areas, but usually bring in a new factors that need to be controlled such as washed out renders. Exponential – This mode will saturate the colours based on their brightness.
Indirect illumination gi seting Hello! We are pleased to share with you a new portion of 3d stuff. Continuing the theme of the correct configuration of V-Ray renderer, in this and the following three tutorials, we look into the second important part of V-Ray settings, the Indirect illumination. This tutorial answers the following questions: - What is the indirect illumination? - How do indirect lighting looks in nature? - How does the global illumination differ from the secondary? - What are the diffuse reflected rays? - How the GI algorithm implemented in computer graphics? - What are the primary bounces and how they differ from the secondary ones? - How the hemispheric diffuse reflections look schematically? - How to setup the GI in Vray on practice? - How the global illumination affects the overall scene lighting? - What is color bleeding and how to fight with it? - What are the GI caustics? - What are the correct values for the primaries and secondaries? Introduction Indirect illumination in nature Why is this happening?
Lesson #04 AE Premult in Nuke « janburda Today´s Lesson is about the great possibility in After Effects to perform a Premultiplied – Matted with Color. Imagine you got a 3D Rendering not on black but for instance on white. At this point I want to say thank you to Christian Zilliken an awesome Lead Shading Artist, I worked with on numerous shows. He supports this tutorial with a little 3D spider Website IMDB: The above rendering is how it should look like, and the below one is how you get it for Compositing. If you just do a Premult on the white Background Image you get something like this Do you see the white Outline, that´s not good. Please, NEVER EVER NEVER run first to your Supervisor complain about the CG Artist and say you won´t start until your Renderings are perfect. Even because you can fix these problems within less than one minute. First we start with with creating a constant with your actual background color, in our case it´s white. It will look like this one.
Surreal Structures Blog | Fran's works, tutorials and industry news I did the cloth simulations in Marvelous Designer 2, the rest of the modeling in 3ds Max, and the textures and lighting with Arion for Max. Hi everyone. Here is my latest pet project: This was rendered using Arion for 3ds Max. Thanks for watching! Hi everyone. Happy New Year everyone! I hope this greeting finds you all well. Does anyone else feel uncomfortable with the new Adobe CC pricing/subscription scheme? Since I’ve just upgraded my CS5 to CS6, I think I won’t have to worry about it for the next few years, but I wanted other people’s input on this issue. RandomControl recently released Rhino LIVE, which is the Arion gpu/hybrid render engine fully integrated into Rhino 3D. Image by Vitaliy Khramoykin Render by Paul Sherstobitoff RandomControl, makers of Arion and Max LIVE have announced the release of Rhino LIVE, fully-integrated Arion for Rhinoceros 3D. See all the details here: Hi everyone, Rendered with RandomControl Arion
The Making Of Country Home Hi all. My name is Nicolás Molina managing partner of sharing with you from Cordoba, Argentina this tutorial on our work "Country Home". Thanks Jeff for giving us this opportunity. This is a project for a future presentation townhome "country" in an environment that emphasizes the architecture. In this case it was based on a model from 3DDD.ru, which was then completed with a new roof, ridges, drains, curtains, deck etc. Original model. Detail and ridge tiles, beveled walls. Detail of drains, curtains and beveled corners. 3D Deck planking added. Detail of the deck. The scene is illuminated by a VRaySun and a 3D dome with a VRayLightMtl applied, which uses a map from VizPeople HDRI. VRay Sun Settings. Material applied to the 3D dome. PhysicalCamera configuration. The materials used are basic. Vegetation was from Evermotion for flowering plants and Itrees for the trees and shrubs. The final image was rendered at a resolution of 2500px wide using a fairly simple setup.
