Using Redshift For Cinema 4D To Render a Glass Ceramic Scene

Final Render In this article, Fox Renderfarm, the best could rendering service provider, will share with you a Redshift production breakdown and experience sharing from lighting/rendering artist Jiaxuan Wang.Introduction: Hi, everyone! This is Jiaxuan Wang. I’m so happy to have gained some popularity for my artwork and have seen my progress along the way.We were given a pretty complex theme, especially on the modeling and lighting. I rendered it with Redshift.!Render without LightingRender without Lighting We can separate the models into 6 sections: foreground, the bridge, architectures on both sides, the cathedral, background and the crowd. When I started dealing with the rendering, it took a very long time since there were too many polygons. Before I could optimize the models, it took nearly 6 minutes just to read the models. So I decided to separate the models. Coincidentally, I found that after dealing with some unnecessary UVs, and combining some models, the time of the input process and the size of the files both would shrink drastically. This allowed me to manage the lighting and rendering with all the models. Thus, for the second time, I input all the 6 files into one to render with Reference. Speaking of texturing, most of the models are attached with textures. Some silhouettes and simple models, I chose to use simple color texture to save time. And the lighting part, besides the radiating window, there are 240 lights in total. A lot of Area Lights were used. Through adjusting the position, strength and so forth to add more details.!A Redshift Production Breakdown and Experience Sharing from LightingRendering Artist-1The first render is not that satisfying. Since this is my first time dealing with this kind of fantasy style, I paid too much attention to working on the fog but ignored the importance of basic lights. Additionally, I just simply multiplied the lights without finding the main light source, which turned out to be a lot of shadows and strong contrast without fine details. My teacher recorded a long video to give me some advice, telling me details like the foreground is too bright, it is too hollow under the bridge, there is no visual focus in the image, etc. I was more experienced on my second render. And I began to think like a concept artist, considering the position of the lights and how I want the shadows and contrast to transit in the picture. Then comes the ambient adjustment, about the fog. Most of them were composited in Nuke afterwards according to my teachers’ advice.!Nodes TreeNodes Tree

This time, the cheapest cloud render farm for VFX, animation, CGI projects in the world, Fox Renderfarm wants to use a case to show the powerful rendering features of Redshift.In this case, C4D and Redshift are used to render a photo-level picture of fresh bamboo. The main elements in this picture are composed of several parts, bamboo and glass bottles, which are the most prominent places in the picture. The difficulty lies in the part of the bamboo, especially the part of the bamboo texture. Scene constructionThe elements of the scene are simple, including tables, books, clocks, bottles and plants in the foreground. It is also possible to use some existing models directly, and choose an angle that shows the bamboo. It is still very simple to see the entire project now.The bottle uses an existing model and there is a layer of water inside the model.There is still a problem. The bottle is empty and needs to add some stones and bamboo. So, to make a stone first, you can add a launcher under Simulate / Particles / Emitter to make a stone.!Zen Bamboo-1 Transmitter settings，!Zen Bamboo-2 Create a sphere to make a stone, then make a different shape, drag all the stones under the emitter, then play to a suitable height and convert the stone into an object. The floating stones can be hidden.!Zen Bamboo-3 Create a bamboo using a Tube.!Zen Bamboo-4!Zen Bamboo-5Create other items for the scene, the wall and the wooden table.!Zen Bamboo-6Place the camera:!Zen Bamboo-7 MaterialThe material starts from the simplest. All the props do not use the Redshift material, but use the Cinema 4D's own shader.The background wall adds a default material to place the lights.!Zen Bamboo-8Add wood grain to the board. !Zen Bamboo-9 Next, the bottle material uses the default Glass. After adjusting the value, copy a layer of glass material to the water level, modify the preset Water, and continue to adjust the value. !Zen Bamboo-10 The stone material uses a random color that makes the stone look more versatile.!Zen Bamboo-11 The bamboo material uses a gradual overshoot to increase exposure.!Zen Bamboo-12 Make a bamboo node using Vertex Attribute and Ramp.!Zen Bamboo-13 Lighting and adding other itemsIn addition to Dome Light, you need to add an Infinite Light to change the brightness and keep the scene from being too bright. Adding a plant from the own plant library to the foreground of the lens, you can see that the effect of the lens is already very good. But trying to achieve the best results requires constant experimentation.!Zen Bamboo-14 Add other items, clocks, books, milk cartons, and photo frames to the scene, all using existing models and materials. Then output the test results.!Zen Bamboo-15 Post-production adjustmentAdjust brightness, contrast, exposure, and change colors.!Zen Bamboo-16

Rendering and previewing in a flash! The craze for Marvel’s superhero movie Deadpool swept over the world.As the first full CGI realistic human feature film in Asia, Legend of Ravaging Dynasties dominated the headlines once the trailer came out.These two movies were rendered with GPU rendering engines.Obviously, GPU computing card and GPU rendering engines are gradually used in film production. It is a good start!Now, as the leading render farm in the industry, Fox Renderfarm launches GPU rendering. Let’s start free trial with Fox Renderfarm’s GPU rendering. Let’s get it started! What’s the differences between GPU and CPU? A simple way to understand the difference between a CPU and GPU is to compare how they process tasks. A CPU consists of a few cores optimized for sequential serial processing, while a GPU has a massively parallel architecture consisting of thousands of smaller, more efficient cores designed for handling multiple tasks simultaneously. Adam Savage and Jamie Hyneman made a painting demonstration to show the difference between CPU and GPU: Mythbusters Demo GPU versus CPU What’s the advantage of GPU Rendering ?In the field of graphics rendering, not only films and animations, but also CG art, GPU with its computing ability and architecture specially designed for graphics acceleration provides the users with a more efficient rendering solution, namely the GPU rendering solution. GPU rendering has great advantage of fast speed and low cost. Moreover, GPU rendering becomes more and more available now, lots of works with high quality rendered with GPU has come out. GPU rendering tends to be popular with users at home and abroad.Thinking of the CPU as the manager of a factory, thoughtfully making tough decisions. GPU, on the other hand, is more like an entire group of workers at the factory. While they can’t do the same type of computing, they can handle many, many more tasks at once without becoming overwhelmed. Many rendering tasks are the kind of repetitive, brute-force functions GPUs are good at. Plus, you can stack several GPUs into one computer. This all means GPU systems can often render much, much faster!There is also a huge advantage that comes along in CG production. GPU rendering is so fast it can often provide real-time feedback while working. No more going to get a cup of coffee while your preview render chugs away. You can see material and lighting changes happen before your eyes.GPU Renderer 1.Redshift is the world’s first fully GPU-accelerated, biased renderer and it is also the most popular GPU renderer.
