Best V-Ray Settings – GI Engines Choice

In this tutorial we will decide, which of GI rendering algorithms such as Brute force, Photon Map, Irradiance map, and Light cache, are the best for calculation of the global illumination. This tutorial answers the following questions. Which GI rendering algorithms are best in Vray? Which rendering engine should we choose for primary bounces and why? With what engine should we render the secondary bounces and why? What problems exist in GI maps and what should be done to eliminate them? Why does the noise or dirt on the fine detail of the scene appear? How to get rid of the smudges in the corners and on the cornices?

Best V-Ray Settings - Light Cache

In this tutorial, we will learn about the GI bounces rendering algorithms Photon mapping and Light Cache. Also, we’ll study in detail the working principle and each function of Light cache, as well as learn about the optimal values of its settings. This tutorial answers the following questions. What a photon map is and how it works? What are the disadvantages of using the photon map? How does a modified photon map algorithm Light cache work? What is a cell of Light cache? How can Light cache store direct light and calculate the diffuse reflections? How and why do the Light cache filters work? What is the difference between Pre-filtering and Filtering? What are the values in the Light cache settings that provide the most acceptable result?

Best V-Ray Settings - Irradiance Map

We continue to setting up the global illumination in V-Ray. In this tutorial, we will look into the principles, parameters and arguments for and against the calculation algorithms of secondary GI bounces Brute Force and Irradiance Map. This tutorial answers the following questions. How does Brute force GI engine work? Where is the Quasi-Monte Carlo GI engine gone? How does the Irradiance Map algorithm work? How does the three-dimensional irradiance map look like? How IM detects the details of the scene? What is IM prepass? Why we should not set the same values of Min and Max rate? How does Detail enhancement option in the Irradiance Map work? What Multipass does? What value of interpolation gives smooth, but detailed Irradiance Map? Why there may be bright light spots on the rendering and how to get rid of them?

Best V-Ray settings - Indirect illumination

This tutorial is about theory and practice of the Global Illumination in 3ds max V-Ray. 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? Global illumination is one of the modern rendering engine algorithms, which adds to the final image an additional render element. For ease of understanding of the rendering engine, the simplest way to imagine forming of final image as...

Free 3D model - Built-in transparent shower cabin

Modern shower canite. Free 3d model designed exclusively for installation in a niche in the bathroom or shower room. The 3d model itself is the double doors to a niche that opens inward and outward by more than 90 degrees. It comes with the matching door shower tray. Door design allows installation at floor level, if the door will be used as a simple partition, but not as part of an improvised shower cabin. Each door leaf is made of large steel rack, fastened to the wall, which with the help of large flat loops hung the glass door. Doors of shower cubicle are also called barn doors. The glass of doors is completely transparent. It is firm and secure through a special hardening firing. Both the vertical face of the glass sheets are equipped with sealing profile that removes the moisture and allows taking a shower, boldly splashing drops of water inside the cabin. Both glass doors are equipped with a handle in a circular design. All parts of this free 3d models, except the actual door glass paintings, stylized by chromed steel material. Shower pan is a solid ceramic part. Porcelain tray is much more robust than plastic tray. Tough ceramics eliminate sagging, even at very large weight of a man who takes a shower. Free 3d model of a pallet is equipped with a drain hole, covered with a special metal cap of the same steel as the 3d models of parts of doors. This stopper allows user to securely protect drains booths from penetrating into the third-party items, hair, particles of soap and so on. In addition, it completely eliminates an annoying loss of jewelry, which were not removed before taking a shower. Niche for the organization of the cubicle can be a recess in the wall, and formed through an extra wall, next to one wall of the shower room. To prevent the destruction of the walls inside the booths, they should be lined with moisture-resistant tiles. Ready-assembled cabin is an enclosed and technically equipped area for showering. Taking a shower in this cubicle turns into something more than just a bath. The ease and adaptability of its design will completely relax in the morning shower and give strength for the day. At the same time in the evening it will help to relieve tension and relax. This 3d model consists of three parts. The first part is a door frame of two uprights with a tray. The second and third parts of this 3d model are the wing doors. Centers of rotation of each set to correct points that allows you to freely open and close winds 3d models, ensuring the most advantageous their position in the desired perspective of created 3d visualization. This free 3d model is a copy of an actually existing shower cabin made in Germany. Modeled in 3ds Max 2008. Rendered with V-Ray.

Free 3D model - Cosmetic extendable mirror

Free 3d model of a remarkable double-sided Italian mirrors in a circular frame. 3d model of a mirror attached to the arch with a handle, which from a distance resembles the slingshot. The mirror itself rotates freely in the fixture by 360 degrees on the horizontal axis. Feature of two-sided mirror is the fact that one side of it is quite normal mirror, while another is magnifying. The second side of the mirror has a five times magnifying, thanks to the special curvature of the surface. This allows user to perform easily a professional make-up right in his apartment or just to get rid of small speck in the eye. This woman's make-up mirror, with a bright light directed at a person, allows her to perform daily facial care, eliminating all even the tiniest flaws on skin. However, it would be useful in clean shave for most men, attentive sensitive to their appearance. Such a mirror greatly simplifies the procedure of putting on contact lenses. Arc, holding the mirror frame is attached to the slide mounts. 3d model of the holder consists of a six flat-connected strips, fastened with rivets. Rivets on the straps are not fastened tightly. They have enough clamps to hold the sliding design in a fixed position. At the same time, they allow its unhindered flexion and extension on telescopic principle, depending on the individual needs to use. This flexibility allows user to precisely position the mirror at the desired distance, increasing the comfort of use, as in this case it obviates the need to stretch oneself to the mirror and balance in front of its face. Sliding mirror holder mounted to the wall. Despite its mobile telescopic design, strict wall-mount makes sliding glass a decorative stationary element of the interior. Everything except the actual reflecting mirror surface is made of steel plated in gold. The most appropriate position of this mirror is the zone on the wall to the right or left of the main bathroom mirror. That is, the mirror is not the main bathroom mirror, it merely complements it. This 3d model of a mirror with a sliding mechanism and rod fastened to the wall, are made separately. This allows you to rotate the mirror, positioning its 3d model in the best perspective on the 3d visualization. Modeled in 3ds Max 2008. Rendered with V-Ray.
