Skillshare – Blender 3D Cycles Rendering Essentials
In this course we will cover the essential techniques of rendering in Blender using Cycles. For those of you who new to Blender, Cycles is a rendering engine that is comparable to V-Ray, Corona, Arnold, Octane etc. Essentially Cycles can simulate real world lighting condition, so it enables us to produce photorealistic images. But unlike the other rendering engines, Cycles comes bundled with Blender so it is free and you don’t need to download or install anything separately. Basically if you use Blender then you already have Cycles.
What we are going to cover
First we’re going to cover how GI rendering works, then we move on to discussing the differences between GPU and CPU rendering. Next we will discuss about rendering samples and different rendering methods. After that, we will cover in depth about light paths and how it can help us to optimize the rendering time. Next we will cover how to control transparency and caustics in Cycles. And then we will cover how to control light range and use the filmic tone mapping. We will learn how to create environment light using HDRI images. Then we will cover more lighting techniques using different types of lamp object and then learn about creating custom shaped light by turning any geometry into a light source.
After we cover the render settings and lightings, we will then move on to materials. We will cover a lot of aspects about the principled shader such as the difference between metallic and dielectric material, creating transmissive materials, subsurface scattering, sheen, anisotropy, clearcoat, specular etc. As a bonus, we will discuss the workflow of how to create any material you can think of and then how to manage materials by creating your own material library. At the last part of this course we will discuss how to do final rendering, creating camera and how to control it. We will have a final project of creating this fish robot rendering. Basically in this project we will apply all that we have learned before, plus we will learn how to take our rendering result from Blender to Krita to create the final composition.
搅拌机三维循环渲染要点
在本课程中,我们将使用循环来描述搅拌器中的渲染技术。对于那些刚接触Blender的人来说,Cycles是一个渲染引擎,可以和V-Ray、Corona、Arnold、Octane等渲染引擎相媲美。Cycles基本上可以模拟真实世界的光照条件,因此它能够使我们产生逼真的图像。但是不同于其他渲染引擎,Cycles与Blender捆绑在一起,所以它是免费的,您不需要单独下载或安装任何东西。基本上,如果你使用搅拌器,那么你已经有循环了。
我们将要做什么
首先,我们将介绍GI渲染是如何工作的,然后我们讨论GPU和CPU渲染之间的区别。接下来将讨论渲染样本和不同渲染方法。之后,我们将深入探讨光路,以及它如何帮助我们优化渲染时间。接下来我们将讨论如何控制周期中的透明度和焦散线。然后,我们将介绍如何控制光范围,并使用电影色调映射。我们将学习如何创建环境光使用HDRI图像。然后我们将涵盖使用不同类型的灯物体的更多照明技术,然后学习如何通过将任何几何形状转换成光源来创建定制形状的光。
在我们覆盖渲染设置和照明之后,我们将继续前进到材料。我们将涵盖许多方面的原则着色器,如金属和介电材料的差异,创建透射材料,地下散射,光泽,各向异性,透明涂层,镜面等。作为奖励,我们将讨论如何创建任何材料的工作流程,你可以想想,然后如何管理材料,通过创建自己的材料库。在本课程的最后部分,我们将讨论如何进行最终渲染、创建相机以及如何控制它。我们将有一个最终的项目创建这个鱼机器人渲染。基本上在这个项目中,我们将应用所有我们以前学到的,加上我们将学习如何把我们的渲染结果从Blender到Krita,以创建最终的构图。
