最佳HOUDINI渲染器-材质工作流程BEST HOUDINI RENDERING ENGINE – Shading Workflow Equivalence

Hi ! This video is going to be a bit different than usual. See that rather as a documentation that can help you move from one engine to an other, or simply get the shading fundamentals of the engine render of your choice.

Video plan :

02:20 : Material Builder / base Shader – Mantra / Renderman / Vray / Redshift

04:40 : Geometry Parameters – Mantra / Renderman / Vray / Redshift

06:07 : Displacement workflow / Mantra-Karma
07:26 : Displacement workflow / Renderman
09:09 : Displacement workflow / Vray
10:54 : Displacement workflow / Redshift

12:46 : Textures with UDIM / Mantra – Karma
13:30 : Textures with UDIM / Renderman
14:21 : Textures with UDIM / Vray
15:15 : Textures with UDIM / Redshift

15:45 : Correcting & Mixing Textures / Mantra – Karma
17:42 : Correcting & Mixing Textures / Renderman
19:26 : Correcting & Mixing Textures / Vray
23:40 : Correcting & Mixing Textures / Redshift

25:16 : Layer Shaders with Attributes / attribute setup
25:42 : Layer Shaders with Attributes / Mantra – Karma
29:36 : Layer Shaders with Attributes / Renderman
31:59 : Layer Shaders with Attributes / Vray
34:53 : Layer Shaders with Attributes / Redshift

The main reason of this tutorial is a lot of you asked me what would be the equivalent workflow to achieve my previous tutorial about Megascan shading using something else than Redshift.

So I figured I had to do something so you can at least translate some workflow I am showing into the engine of your choice.

Just to be clear I’m not here to argue which one is best… I couldn’t care less about that, nowadays everything is able to achieve photo-realistic results. Now your choice may depends on on your taste, pipeline but also your hardware.
In my case I have been using a gaming laptop for my personal projects and tutorials … so a GPU engine like Redshift was the best fitting my needs.
So today I’m going to focus on a tight selection :

– Mantra/karma which is integrated by default within Houdini. So there is a high chance you may use those at some point. Karma supports USD which is great to work within Solaris. And Mantra can render your Obj context for free.

– Pixar’s renderman which is a pretty powerful combo with Houdini since it handles USD and Solaris. Also side note, you can use renderman for free for non-commercial project. So no excuse to try this out. https://renderman.pixar.com/

– Redshift : one of the promising GPU engine on the market. Personal favourite because very straightforward and powerful.

– VRAY : Extensively used in the VFX Industry. And is now compatible with Houdini. Chaosgroup offers 30 day for free, I invite you to check this out if you’re interested

We won’t talk here about octane, arnold or 3delight. But there are also very solid renderer and very well integrated with Houdini ! Maybe we’ll see that next time.

嗨！该视频将与平时有所不同。而是将其作为文档，可以帮助您从一个引擎转移到另一个引擎，或者只是获得您选择的引擎渲染基础知识。

本教程的主要原因是很多人问我，使用Redshift以外的方法来实现我以前的Megascan着色教程的等效工作流程是什么？
https://youtu.be/5QeCKNnso0A

因此，我认为我必须做一些事情，以便您至少可以将我正在显示的某些工作流程转换为您选择的引擎。

为了清楚起见，我并不是在这里争论哪一个是最好的。。。我对此并不在乎，如今，一切都可以实现照片般逼真的结果。现在，您的选择可能取决于您的喜好，流水线，还取决于您的硬件。
就我而言，我一直在为个人项目和教程使用游戏笔记本电脑……因此，像Redshift这样的GPU引擎最适合我的需求。
因此，今天我将重点介绍一个紧缩的选择：

-咒语/业力默认情况下集成在Houdini中。因此，您很有可能会在某些时候使用它们。 Karma支持USD，这在Solaris中非常有用。 Mantra可以免费渲染您的Obj上下文。

– Pixar’s renderman which is a pretty powerful combo with Houdini since it handles USD and Solaris. Also side note, you can use renderman for free for non-commercial project. So no excuse to try this out. https://renderman.pixar.com/

-Redshift：市场上有前途的GPU引擎之一。个人最爱，因为非常直接和强大。

-VRAY：在VFX行业中广泛使用。并且现在与Houdini兼容。 Chaosgroup免费提供30天，如果您有兴趣，我邀请您查看

我们在这里不会谈论辛烷，阿诺德或3delight。但是也有非常坚固的渲染器，并且与Houdini很好地集成在一起！也许下次再见。
