How To Train Your Dragon 3 Get A High Score For Its Visual Effect

Shenzhen, China – When it comes to cloud rendering services, Rayvision has made a marked impact in the IT industry. In addition to being a pioneer of self-service , Rayvision became one of the pivotal sponsors, in the exciting 3D CG Sci-Fi Challenge for talented graphic designers. At a recent conference, a spokesperson for Rayvision said, “We believe that the best way to grow and develop is to help instill fresh new talent and ideas in a positive direction. We have always been adamant supporters of promoting new talent. As sponsors for the 3D CG Sci-Fi Challenge this year, we are proud to help talented graphic designers exhibit their futuristic visions and dreams on a greater and more realistic scale.” The best, visionary proposals of the competition will receive some notable prizes. These include a $250 render fee for the first place winners, $150 for the first runner up and finally, a render fee of $100 for the second runner up. Along with sponsors DreamWorks, American Industrial Light and Magic, SKG and various other animation companies from all over the world, Rayvision provides talented individuals the chance to explore and grow in CG. The 3D Sci-Fi Challenge focuses on honing and testing the skills of talented individuals who have the capabilities to envision an “alternative” universe with respect to a dystopian or utopian future. This challenge will run from February 20th to April 17th, 2015 and is open to everyone, including teams, and talented graphic designers from all over the world. Each participant has the freedom to upload more than one entry model and stand a chance of qualifying for the portfolio category if they upload more than eight models. “We suggest that everyone try their skills by participating in this grand event!” added the spokesperson. The CGTrader Staff, will judge each entry on quality, innovation and presentation. About the Company Shenzhen Rayvision Inc. is an internet technology company that specializes in research into cluster rendering and parallel computing technology, providing computing services for . It is the pioneer of ‘self service could rendering’. Renderbus, its brand, was the first company in China to offer a cloud-rendering platform. For the purpose of providing consistent service for CG studios in the world, RAYVISION Inc. launched a family brand, “RAYVISION”, globally, based on Renderbus (its domestic brand) and Fox RenderFarm (its overseas brand), in 2014. Rayvision promises to provide global users with more excellent, stable and consistent .

Rendering is a very important part during the 3D production. This step will generate the final image including information such as models, scenes, textures, vfx and lights. Rendering in film and television effects is computationally intensive and requires a lot of server computing, especially for animated film production, where rendering time is almost a big challenge. So for the producer, is a good choice. ## Why the render farm can make you work faster and better? The render farm is also called the conputer cluster. It refers to the calculation method of a supercomputer built with an existing CPU, Ethernet, and operating system. The render farm are consist of thousands of servers. is an upgrade on the render farm. We can upload the material to the cloud and use the render farm for calculations remotely. And the server will distribute the files to multiple servers and render them according to the uploader's choice. For example, a 10 second special effect lens, 10 hours for a single machine rendering, then if you use 10 machines to render, then the rendering time becomes 1/10. ## Cloud rendering has the following advantages 1. No geographical restrictions, wider market scope, lower idle rate and cost savings. 2. Render farm with better server configuration to ensure user safety and efficiency. 3. Control the rendering progress anytime, anywhere. The emergence of cloud rendering has almost swept the CG industry. It not only brought great changes to the CG industry, but also provided strong support. For the fast-paced modern, it is more convenient, which is why more and more people choose the to render that works.

Step 1: Creating the ball as a simple animated scene. Step 2: Turn on motion blur: Render a reference to motion blur. Step 3: Follow the method given in the official Arnold documentation: Change the camera's Shutter Start and Shutter End to 0.5 (why changed to 0.5 because my motion blur type is Center On Frame). Step 4: Create a channel for AOV motion blur: Here I will create two motion blur channels: The first is the motionvector channel that comes with Arnold; The second is to use the custom motion vector AOV of motion vector shader (giving the aiMotionVector material in the AOV channel). Cloud rendering note: MBlur is named according to your preference. The setting of aiMotionVector was wrote in the previous article. Step 5: Render this image to see two motion blur conditions. It can be seen that both the motionvector and MBlur motion blur channels in our AOV channel are in the wrong direction. Step 6: Next I will officially explain how to solve this problem: From the beginning. A: Turn on the Motion Blur button in the render settings: I chose the Center On Frame mode here. B: Change the Shutter Start and Shutter End in the camera Arnold attribute to 0.5, respectively, corresponding to the Center On Frame mode. (Note: When rendering the motion vector AOV, the camera Shutter Start and Shutter End should be the same value.) C: Create a new MBlur_2 channel in AOV (to compare with the previous MBlur.) D: Open the material editor and find the two nodes aiMotionVector and aiVectorMap under Arnold's material panel. 1) Connect the outColor of the aiMotionVector node to the input of the aiVectorMap node. 2) Then connect the outValue in theaiVectorMap node to the DefaultValue in the Shader property of the MBlur channel in AOV. 3) Change the XYZ mode of the Order in theaiVectorMap node to YZX mode and remove the hook of the tangentSpace. 4) In the aiMotionVector node, enable Encoding Raw Vector. E. After the above steps are completed, start rendering the image and view it in Nuke. As shown in the figure: Maya's default motion blur is basically the same as the MBlur_2 channel we made in AOV, and the motion blur adjusted by Nuke is basically the same. Of course, I also found a bug in the Arnold renderer, its motion blur channel does not solve the shadow of motion blur, there can be seen in a big picture that cloud rendering attached below.
