There is one disgusting thing while rendering complex scenes in V Ray. It can make most V Ray users nervous. It can even fully disarm someone, killing any enthusiasm to continue any further work on the current scene. Especially unexpected and tricky this thing becomes when one is working on the commercial rendering with clearly defined deadline. All forums and discussion boards about V Ray renderer are just snowed under with the pleading requests for help in completion rendering of heavy scene DOf course, we are talking about the lack of RAM during rendering, which is the prevailing reason of 3ds Max and V Ray system crash. Why is this happening What causes this errorThe story behind 5SRW After more than 10 years of development, 5SRW is today the most important method to learn VRay following the photographic approach. Realistic VRay 3ds Max interior scene, fully textured with high resolution textures, realistic shader setup, with very detailed 3d. Realistic VRay 3ds Max. Il rendering un termine della lingua inglese che in senso esteso indica la resa o restituzione grafica, ovvero unoperazione compiuta da un disegnatore per. Cant you do anything simple Can it really be true that to complete a big project we inevitably need to increase the amount of RAM, installed in computer Is it true, that the only way out is to go to the computer store and buy a few more sticks of RAM To answer these questions, let us see how V Ray uses the memory and what tools of managing the process of its use are available to us. REAL TREES is a highly realistic tree model library for architectural visualization in 3ds Max, CINEMA 4D, LightWave and MODO. These files are available under a sort of open source concept. They are intended for educational use but really can be used for whatever the fuck you want. FAQ and answers for some common questions about Corona Renderer, and some places to ask for additional help. Heres a free Kitchen Layout Scene for you to download originally modeled in 3ds max 9 then exported to Lightscape and the Lighting setup with radiosity was done. In any software, the memory management and the way of placing the data there is a very complicated and routine material. Well, at least it is a true for 3d artist. There is absolutely no sense to go deep into describing the data arrays and the ways of addressing to them. Such details are deeply rooted in the programming field. For easy managing the RAM of any software at a professional level, you have enough to know only the general idea about the processes occurring in it. Especially, considering that the user is entirely limited to the proposed interface. V Ray is not exception here. Raycasting, the Basis of V Ray Rendering. Before start the rendering, V Ray has to load into RAMthe scene geometry for operative using it during calculation of the final image. This is the initial aspect of the entire rendering process. After realizing such necessity of renderer, the importance of memory management in the rendering immediately becomes clear. But, of course, we wouldnt just stop on this and will follow the order of rendering step by step. Once data is loaded into memory, V Ray rendering can begin. The calculating of each pixel starts with the basic operation, namely the probing the geometry. This is done by using a special algorithm, the so called ray casting. The essence of this algorithm is that camera shoots a ray, which that flies until it hits some object in the scene. Each ray intersection is fixed and thus V Ray determines the location of geometry in the scene, its basic properties and other information required for further rendering. Disadvantages of Not Organized Data. The process of calculation of the single raycast, i. However, the number of raycasts during photorealistic rendering can exceed manyfold the number of rendered image pixels. For example, the HD 1. This scale changes the situation fundamentally, making the raycasting process very resource intensive. Let us take a formal analogy to the technically complicated raycasting algorithm. This analogy will greatly help us understand the specific problems of memory management in V Ray. So, lets imagine the scene geometry as a set of usual green tree leaves, and the raycasting algorithm as a tireless ant, which have to find the most delicious yellowish leave amongst all green ones. In our analogy, this yellow leaf will embody the needed data about the geometry, hit by a raycasting ray. Initially, the data on the scene geometry, which will be loaded into memory, is arranged randomly in terms of raycasting process. Let us similarly suppose that all the leaves were chaotically thrown into pile. Our hard working ant knows that he needs to find a yellow leaf among the myriad of unnecessary for him green ones. How can he do this Of course, he will have to go sequentially through a bunch of green leaves, starting from the closest to one, until he find the one and only yellow leaf. He will have to approach first leaf and see whether it is yellow. Then, come up to the second and look if he needs the second leaf. After this, he has to go to the third one, and again check if that is yellow. Thereby, our ant needs to go through literally every leaf until he finds the desired yellow one. The situation when the ant reaches the yellowish leaf at the beginning of his search is probable. However, there is also absolutely no guarantee that the yellow leaf not be the latest in pile. In such case, to find a single yellow leaf, our ant would have to go over the whole pile of greens. A similar situation can occur with unorganized data on the scene geometry. Raycasting algorithm will be forced to sequentially go through all the geometry for determining the properties of a single point in the scene, which was intersected by raycasting ray. This method of finding the required information is too tedious for our imaginary ant, as well as for the computers CPU, which instead of actual rendering has to busy oneself with non rational searching of data in memory. BSP tree and Convenient Data Structuring. To expedite the process of determining the properties of the scene geometry by raycasting, V Ray organizes all the geometry into a special convenient structure. V Ray lays out the geometry on the shelves of the hierarchical tree structure into RAM. This structure is called the Binary Space Partitioning BSP tree. It is a special method of presenting an array of data as a binary tree structure. The BSP general idea is that scene with all geometry is subdivided into two parts. This action creates the two branches extending from the origin the scene, which is called the Root of the tree. After the first subdivision, each of the data branches emanating from the root, are again divided in half, forming new branches. Points from which the new branches emanate called the Nodes of the tree.
