On VrayProxy production in the 3dsmax scene to optimize management of large application analysis

Paper Keywords: VrayProxy; 3dsmax big scene optimization
Abstract: With the continuous improvement of visual requirements, industry 3dsmax making a higher quality requirements, rendering the whole model is the way to meet this demanding one with the full model rendering application how the limited computer resources under the conditions to accelerate the production process, the successful completion of the project, the industry needs to solve the problem. the author through years of practical experience, their own juice VrayProxy principle and application of tools to do the research skills to explain, for the above problem provide a solution.

An impact speed of problem analysis produced 3dsmax
3dsmax production of higher quality requirements, it means that models need to produce more sophisticated, more realistic lighting, more complex material, more realistic special effects, more precise movements, etc. This is not just a simple ring sum, but the project will be doubling the production cycle and rendering the output of the time. and the scene beyond the computer the number of faces of the affordable range, but also cause crashes, file corruption and other serious conditions. to building animation example. a complete architectural animation, the need for construction of the main building with King, Green and landscape. the number of construction related to the construction of surface appearance and image quality is not a great deal of streamlining. Usually we will streamline the number of faces in the scene and with think of ways on the green, usually in green architectural animation, using maps instead of the model; building animation with King used instead of model geometry and other methods to save face.

In pursuit of better results, and now the whole industry to use the basic model rendering, rendering the whole model is in the scene using the model of each object, so it tends to be more realistic visual effects, but the effect is closer to the true model, then used of the more natural faces, taking the greater the computer's resources. a lot of graphics will increase the number of faces show a great burden in view of the operation time will be delayed, often just a few minutes of the steps, sometimes need to wait ten minutes or longer to complete the calculation. when the cause of serious crashes and 3dsmax automatic pop-up phenomenon.

2 3dsmax rendering process status
In the early production, animation, rendering uses a built-in lighting system and 3DSMAX renderer with the default output of this production method has the advantages of speed, but because the scene is the production of light physical phenomena were simulated by , so the effect of rendering is not true, especially in the big scene, you need to play a lot of light, the program is more complex.

But with the introduction of advanced renderer, the rendering process has been optimized, high-level renderer is based on an algorithm to calculate the physical phenomena of light in the scene, so the effect of rendering more realistic, lighting settings are also just follow the actual lighting can be arranged and it was such a big production team have chosen to senior project production renderer, while in many of the advanced renderer, VRay, with its rendering quality and speed in finding a good balance between the advantages to be industry recognition and is widely used.

3 VrayProxy works
Vray Chaos Group is a well-known developed renderer, but VrayProxy is one of its tools. VrayProxy 3dsmax rendering tool is to allow external file leaders from mesh, so your work can save a lot of resources in . analogy, a scenario tree model requires a lot of precision, but too many trees in the production process model is resource-intensive. At this point we can export VRay proxy object tree, then the object by the VRayProxy tool to guide agency back to the scene in which, at this time scenario in the model is only a proxy for the external object model, not the number of faces, do not take up resources that we use this technology can render tens of millions or more of the surface, far beyond the affordability of its own 3dsmax range and can also speed up the process. effective to avoid too many faces, resulting in delayed or not rendered operational view, pop-up phenomenon.


4 VrayProxy to use
Vray renderer is because third-party plug-ins, so you need to install to use, each has a corresponding renderer Vray 3dsmax version, only in order to properly install the corresponding version. VrayProxy tools Vray1.5 version of the introduction of new features, so you need to install Vray 1.5 or higher to find the first step to open the menu rendering 3dsmax render settings panel in the "public" tab find "Assign Renderer" rollout in the "product class", choose VRay renderer. The second step in the scene select agent model, "the script input bar" input "doVRayMeshExport}" or select the state in the model, right click Choose '`VRay meshexport" tool in the pop-up "VRay mesh export" panel "Folder" column set the save path in the "File" field input the name of export agent object, click "OK" to save to complete the third step in the main toolbar 3DSMAX "Create Panel" found under the "geometry" in the drop-down menu to find the "Vray" module, click on "Vrayproxy" tool, click the left mouse button in the scene, the object selection dialog box will pop up agency , choose to export just a proxy object, to complete the creation.

Use a proxy object in the scene model is usually established after the completion of rendering the test before, so keeping the original location of the scene model is important in VRaymesh export panel, we can check Automaticallycreate proxies option to solve this problem. Automatically createproxie, options are automatically replaced by proxy objects in the scene model, and maintain the same position the model for the composition of objects by a number of models, such as the tree by the trunk, branches, leaves form. We need to collapse into the first model an object, then the agent into so you can more effectively conserve resources.

For more than two or transformation of objects, we can through the VRay mesh export panel, check the Export as multiple files option to achieve the multiple objects combined into a proxy object.

In the new version of the Vray1.50.sp2 renderer, regardless of the number of faces of the original model number, its agent, the display of objects in the scene plane number 10000, we can set up two ways to achieve the purpose of optimization.

The first: the object into the agent's "Edit" panel to find the "Display" tabs, here are three display modes to control the display of proxy objects, the number of faces. "Bounding box ', so that proxy objects to the shape shown BOX In the view, take the number of faces of 12 triangles. "Preview from file" to proxy object to the original shape of the object shows the number of faces as the default number of 10000 faces. "Point" proxy objects to point to the shape shown number of a display surface.

The second: "Vray mesh export" panel "Faces inpreview ', column, this parameter is to control the proxy object in the display mode to" Preview from file "state, the scene shows the number of faces.

6 VrayProxy analysis of the use of
Using Vray proxy objects, you must use VR renderer rendering, otherwise the results can not be rendered correctly. Once the model into a proxy object, the can not be modified, so the proxy object into the model should be determined in the model into a proxy object after material can not be set, and create a proxy object is not material, so the material in the model set before conversion, and save the material has been prepared called. Repeated in the scene for the model, such as trees, flowers, lamps, etc., we only need to convert a model, then copy it associated. Associated with replication advantage no matter how many copies of your copy, the memory is the same , so as to avoid a memory overflow error situation. agent object type should not be too often repeated the scene more proxy objects, because objects of many kinds of agents will take a lot of resources, slow down.

7 Conclusion
Whole-industry model rendering in the case, because the number of faces caused by excessive speed the production process to reduce the production cost increases, the industry has been eager to solve the problem, and rational use of Vray proxy object tool to solve this problem provides an effective program.
