The Essential Thinking Of Roughness And Anisotropy (2)

As a leading cloud rendering service provider, also a Redshift render farm, Fox Renderfarm published an article about “The Essential Thinking Of Roughness And Anisotropy (1)” last week. However, If you follow the view, you will find that you don't need the roughness parameter at all. The rougher the reflection, the better the texture with a higher bump strength is solved, let’s continue to discuss the roughness and anisotropy.

In theory, this statement is correct, and it is also very physical and in line with people's real life experience. But this kind of practice of using roughness to make roughness, there is a professional word to describe him, everyone who plays rendering should be familiar with it - brute force.

The reason is the same. This way, when you render GI, use the brute force algorithm to mean that the microstructure you express may be very accurate, but the rendering speed is extremely slow. maxAA = 4 maxAA = 117 maxAA = 1024 maxAA = 8192

As can be seen from this set of graphs, when the roughness parameter is used to adjust the reflection roughness, there is no noise at very low sampling. But with bump control, very high sampling is required to effectively reduce noise. And even if the sample is given to the system with a maximum value of 8192 (the pictures are rendered using the Redshift renderer, the sample unit of rs is the square of the value of the sample equivalent to subdivs, where 8192samples is equivalent to about 90 of the subdivs; In addition, using maxAA to improve quality rather than using lighting samples is because the noise is not caused by insufficient light sampling, but the texture is very fine and must be super-photocamera to sample, and still see obvious noise.

That is to say, this idea is only theoretically correct, but it is a big mistake in production and industrial processes.

Then the roughness parameter was introduced to solve the problem discussed above.

Now please follow the best CPU&GPU render farm and cloud rendering services provider to our next part: The Essential Thinking Of Roughness And Anisotropy (3).

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 services 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

Arnold\ V-Ray\ Octane\ Conora\ RedShift, Which Is The Best 3D Renderer?
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 services provider, it helps you to render 3D models effortlessly offline.
