How to render large scenes with Redshift in Cinema 4D

How to manage large scenes in Cinema 4D's Redshift renderer, how to optimize things in the scene, and how to optimize rendering settings in the Redshift renderer. These are relatively far-reasonable things. How to optimize them is very helpful for scene management.

  • Proxy file

For the Redshift renderer, you can generate proxy files from the scene and export them before rendering. For trees, the scenes with a lot of flowers and grasses are very suitable for the Redshift renderer. This is the theme that the leading cloud render farm in the CG industry, Fox Renderfarm, brings to you in this article.

How to generate a proxy file? Now you need to generate the proxy file and export the Redshift Proxy (*.rs) to where it is needed. Proxy settings: after the ‘Add’, ‘Proxy to Scene’ are checked, the generated proxy file will generate a proxy file in the location where you want to export the file. If the exported file is animated, then ‘Range’ must be changed to ‘All Frames’. Then the generated proxy file will not occupy too many scene resources, and the production software operation will be smooth. And if you use a proxy file for replication, it will also reduce the resources of the system.

Like the scenario below, most of the models are proxyed, so the rendering resources needed are even more economical. Take the following scenario as an example. Its number of faces is very large, and it will be stuck when it is operated. And all the models in the scene do not use proxy files, so you must optimize the rendering settings.

  • Sampling

Before optimization, you must have a certain understanding of the working principle of Redshift. In the default case of Redshift, it does not emit light to the object through the light to show the light and dark effect. Redshift is the light emitted by the camera, hit on the object, and then the object will look for the source of the light to present the light and shade, which is somewhat different from other renderers.

The two values in the picture below are generally used to reduce noise. Samples Min means that the minimum amount of light emitted from the camera is four, and the value below Samples Min can adjust the secondary reflection of the object.

Sampling principle

Noise

The Samples MAX value, if adjusted too high, the camera calculations consume more resources, rendering time will increase a lot. In general, the values are around 64. However, if the motion blur is turned on, then the value should be at least 256 or so.

Samples Min=4, Samples MAX=256

Samples Min=4, Samples MAX=16

If the noise is obvious, try to adjust the ‘Brute Force GI/Number of Rays’ under GI.

GI adjustment

The ‘General/Primary GI Engine’ under GI is a primary feature, and the Secondary GI Engine controls the number of bounces.

Calculating the GI information of the scene under /Primary GI Engine/Irradiance Caching will be faster. The number of light carried by Num Rays, Adaptive Amount represents the attenuation ratio of divergent rays. If Num Rays is 200, then Adaptive Amount 0.8 will decay by 80%.

The above are several ways to optimize large scenes and rendering. By optimizing the scene and rendering settings, you can save more time and resources during rendering, and better complete the scene production.

Arnold\ V-Ray\ Octane\ Conora\ RedShift, Which Is The Best 3D Renderer?
Nowadays, many people use 3D software to create their works, so the use of the renderer is essential. There are many popular renderers, including V-Ray, Octane, Arnold, Conona, RedShift. Of course, there are those who will choose cloud render farm for their rendering. But for many new 3D artist, which renderer is the best?The principles of these renderers are basically the same, but the operation methods are somewhat different. Of course, the focus of each rendering is different. Let us take a look at it now. Which is the Best 3D Renderer?The work from the Runner in Evermotion 2017, rendered by V-Ray: V-Ray The V-Ray renderer focuses on interior design and outdoor design for 20 years. The biggest feature is that it is almost half of the building performance, and the latest 4.0 version of the various functions are also very perfect, many works can be fake.Disadvantages, perhaps because V-Ray has too many setting parameters, material adjustment and lighting performance is very difficult, not very friendly to novices! ArnoldArnold renderer is very powerful. The physics-based ray tracing engine CPU renderer is the most stable! Of course, the CPU is not strong enough, the rendering speed is also anxious, especially the rendering of transparent objects such as glass, as well as its powerful node-like operation, so that novices love and hate it!Of course, as an attitude to study the renderer, Arnold is highly recommended to learn! RedShift Next, talk about RedShift, the GPU-based renderer, the most intuitive experience is that the real-time preview and rendering speed is fast, and has a powerful node system like Arnold. It is more suitable for artistic creation, especially for animation. As for the authenticity of the rendering effect, it takes a lot of time to practice and accumulate knowledge. Octane Octane is also a GPU-based renderer. First of all, its SSS and replacement functions are quite good.The speed is also very fast, the light is softer, and the rendering looks very comfortable. Similarly, if the slightly larger scene is solved by PL, the efficiency will drop, but the speed is not fast. There are also problems with dryness that can sometimes become one of the features of the work!PS: The current version of OC does not support A card, nor can it exclude lights. CononaThe work from the first place of Evermotion 2017, rendered by Corona: Conona is also a highly recommended renderer. It comes from V-Ray. It can be seen as a simplified version of V-Ray. LightMix lighting solves the trouble of late dimming. The material system will not have to worry about it by default. Very small and practical, quick to get started, of course, just out of the official version, it is said that next year will be a node system, while the animation is somewhat weak!If you do indoor and outdoor design, static frame rendering can be used, after all, it is best at the ray tracing rendering engine! ConclusionIn fact, the renderer is just a step in the work, we can choose different renderers according to different work content, find the best for you. There are also many people who choose Fox Renderfarm because as the best CPU & GPU cloud rendering service provider, it helps you to render 3D models effortlessly offline.

A Redshift Production Breakdown and Experience Sharing from Lighting/Rendering Artist Jiaxuan Wang
A Redshift Production Breakdown and Experience Sharing from Lighting/Rendering Artist Jiaxuan Wang
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

Using redshift to render a work Zen Bamboo
Using redshift to render a work Zen Bamboo
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
