Gumroad – Imperfections for Texture and Look Dev By Zak Boxall

这些纹理与任何渲染器或软件包兼容。作为奖励，我刚刚上传了我慢慢增长的 Mari Gizmos 收藏的 v1。

如今，我们越来越接近我们的模型，这就需要我们的表面具有更高的保真度。在过去的几年里，我一直在进行更多的程序化工作并分层我的纹理。

但我一直遇到的问题是试图让这些瑕疵感觉自然和现实。现实世界充满了在 CG 中难以重现的随机细微差别。我使用了从我在网上找到的图像生成的纹理，并尝试重新创建蒙版，但失败了，我使用 Designer 从程序上从头开始制作我需要的东西。然而问题是，很难将你需要的东西与图像区分开来，而且程序生成的垃圾没有我一直在寻找的保真度或自然主义的细微差别。所以我决定手工制作我自己的材质包。

利用我在纹理和外观开发方面的经验，我制作了这些纹理以尝试完成您在现实世界中看到的细微瑕疵。此包中包含 50 个手工创建的灰度扫描。它们清晰锐利，中点为 0，这使得覆盖或混合到您的材质堆栈或着色器网络中变得非常容易。使用这些叠加层的美妙之处在于，它们可以像您需要的那样沉重或微妙。没有任何地图被剪裁以确保良好的衰减，并且可以对它们进行分级以执行您需要的任何操作。我做了很多超级快速的示例来向您展示如何使用这些地图来创建许多不同的外观。

如何使用这些：

• 涂抹在表面以破坏镜面反射

• 在表面添加微尘

• 颜色的自然有机缺陷

• 显示着色器的划痕——例如油漆划痕

• 表面的微划痕、凹凸、位移，可以转换为法线贴图。

• 大量各种高频和低频的垃圾，以在镜面反射上添加细节，在表面、凹凸、位移和位移中添加细节。

• Grunge 可以用作程序蒙版来显示不同的着色器，例如污垢、泥浆、油、血、油漆碎屑——任何你想要的。

• 滴水图模拟玻璃上的干燥残留物——频率变化。

您可以使用 4k 或 8k 尺寸。它们都是手工制作的，以确保它们是无缝的，质地没有柔和的过渡。您可以将这些贴图用于 VFX、游戏、拱形视觉 – 基本上是任何需要在表面自然分解的 CG 模型。

These textures are compatible with any renderer or software package. As a bonus I’ve just uploaded v1 of my slowly growing collection of Mari Gizmos.

Nowadays we are getting closer and closer to our models, which is creating the need to have a much higher level of fidelity on our surfaces. Over the past few years I’ve been working more procedurally and layering up my textures.

But the problem that I’ve always had is trying to make those imperfections feel natural and realistic. The real world is full of random nuances that are so hard to recreate in CG. I’ve used textures generated from images I found online, and tried to recreate masks of what, failing that I’ve resorted using Designer to make what I need from scratch procedurally. However the problem is, it’s so difficult to separate what you need from images, and procedurally generated grunges don’t have the fidelity nor naturalistic nuances that I’m always looking for. So I decided to make my own texture pack by hand.

Using my experience in texturing and lookdev, I’ve made these textures to try to accomplish the subtle imperfections that you see in the real world.Included in this pack are 50 hand created greyscale scans. They are crisp and sharp, with a mid point of 0, which makes it really easy to overlay or mix into your material stack or shader network. The beauty about using these overlays is they can be as heavy or as subtle as you need them to be. None of the maps are clipped to ensure a nice falloff, and can be graded to do whatever you need from them. I did a load of super quick examples to show you how these maps can be used to create lots of different looks.

How you can use these:

• Smudges across surface to break up specular reflection

• Add micro dust onto surface

• Natural organic imperfections in colour

• Scratches to reveal shaders – such as scratching of paint

• Micro scratches in surface, bump, displacement, can be converted into a normal map.

• Massive variety of grunges both high and low frequency to add details onto specular, add details into surface, bump, displacement and displacement.

• Grunges can be used as procedural masks to reveal different shaders, such as dirt, mud, oil, blood, chipping of paint – whatever you want.

• Drip moisture maps to simulate dried residue on glass – variation of frequencies.

You can use either the 4k or 8k sizes. They are all made tillable by hand to ensure they’re seamless with no soft transitions in texture. You can use these maps for VFX, games, arch vis – essentially any CG model that needs natural breakup in the surface.
