The Essential Thinking of Roughness and Anisotropy (5)

As a leading cloud rendering service provider and CPU & GPU render farm, Fox Renderfarm published an article about “The Essential Thinking Of Roughness And Anisotropy (4)”.

In this article, we first learn the principle of directly creating an anisotropy rotation map by bypassing the flowmap. Since the flowmap is not so intuitive, it cannot be used directly in some renderers (vray, redshift). We can start by trying to make an anisotropy rotation map directly.

The tool used is of course the program texture overlord - the substance designer.

First of all, we have to clarify the goal, know exactly what the texture effect to achieve, and then want to make a plan. Now let's analyze what features have been verified and feasible.

We will re-combine the pixel process node in SD before, use -0.25 instead of -0.25, this will make the final output picture brightness completely within the range of [0,1], so that we can observe the picture characteristics. (The only meaning of this operation is for good observation).

Now the picture looks like this, it shines a lot. All brightness is between [0, 1].

At this time, we use a node called histogram select in SD to observe the picture, so we can see how the scratches of different brightness in the picture are distributed.

The figure below shows the effect of sweeping the original image from 0-1.

Here we can find two characteristics of this picture:

Carefully staring at one end of a line, you will find that the line has rotated 360 degrees completely in the process.

Under the same color gradation, the direction of the scratch is basically uniform. Why can such a feature create a ring-like scratch? This is related to the attributes on our shader.

The material sphere has an anisotropy rotation property that specifically controls the direction of rotation of the opposite sex highlights. The input range of this attribute is [0,1], and the value has a corresponding relationship with the angle:

0 : 0°

0.25 : 90°

0.5 : 180°

0.75 : 270°

1.00 : 360°

The middle is the linear difference, and you should understand this parameter very easily.

The figure below shows the effect of anisotropy rotation changing from 0 to 1. The highlight is turned 360 degrees:

So in fact, we only need to make a scratch map that meets these two characteristics to achieve the goal:

The brightness of each scratch changes with the angle

The same angle of scratch brightness is the same

This is shown by the diagram (rotate 0 = rotate 1)

After knowing the principles and goals, we have to find a way to achieve this, a simple implementation in Substance Designer.

This one we only want to talk about ideas, because friends who will use SD software should be in very few.

However, if you already understand the above ideas, you can do it in theory with ps, but it is quite a lot of trouble.

Node graph is relatively simple.

The main thing is to use the tile sampler to do the scattering, the shape node is a square, pressed very flat to make scratch elements. A Gaussian noise makes the spread random.

This gaussian noise should control the rotation and brightness of the scratch at the same time. The final effect is that the darker the gaussian noise is, the smaller the rotation angle is, and the lower the scratch brightness is.

The resulting aniRotation texture effect, SD is naturally seamless.

Then use the histgram select node to check the effect, because we are using a black background, so when the brightness is 0, the large area of the screen is selected, this does not matter, the overall effect looks the same as we expected:

Because this is the simplest implementation, this scratch is not a fancy thing, it is straight. The core principle is the content described above.

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 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.The 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 Tree
