Cinema 4D Particles RS渲染C4D粒子

Particles

粒子

Redshift supports a number of different particle setups that can be rendered inside of Cinema 4D. These include the native particle system, particles imported in through Alembic files from programs such as Houdini, as well as plugins like X-Particles. These particles can be rendered out as simple instanced primitives, custom geometry, or using Redshift's native optimized sphere primitive. You can view the benefits of each one here.

红移支持许多不同的粒子设置，可以在 Cinema 4 d 内渲染。这些粒子系统包括本地粒子系统、从类似 Houdini 的程序通过 Alembic 文件导入的粒子，以及类似 x 粒子的插件。这些粒子可以被渲染成简单的实例基元，自定义几何，或者使用红移的本地优化的球基元。你可以在这里查看每一种方法的好处。

Redshift Object Tag

红移对象标记

The Redshift Object Tag allows you to adjust different particle parameters, per emitter/source in your scene. This can be applied by right clicking our emitter and finding the Redshift tags section.

红移对象标签允许你调整不同的粒子参数，每个发射器/源在你的场景。这可以通过右键单击发射器并找到红移标记部分来应用。

Particle Parameters

粒子参数

Redshift allows you to control the individual shape of each particle from a list of presets, as well as letting you define the particle with custom geometry we can drag and drop. We can also control the overall scale of our particles with the Scale Multiplier.

红移允许你从一个预设列表中控制每个粒子的单独形状，也允许你用自定义的几何图形来定义粒子，我们可以拖放。我们也可以用缩放倍增器来控制粒子的总体尺度。

Mode

模式

There are 5 different particle modes that are described below, including the visual and technical differences.

下面描述了5种不同的粒子模式，包括视觉和技术上的差异。

Sphere Instances vs 球实例 vsOptimized  优化Spheres 球体

The benefits of using the native sphere primitive (Optimized Spheres mode) is that it's very lightweight, even more so than an instance also it can go out of core. Instances are also fairly lightweight in terms of memory, but when you start getting into the millions you can run into out-of-VRAM problems. When working with extremely high counts of particles the Optimized Spheres mode is recommended.

使用本机球原语(优化球模式)的好处是它非常轻量级，甚至比实例更轻，它还可以离开核心。实例在内存方面也是相当轻量级的，但是当您开始使用数以百万计的实例时，可能会遇到超出 vram 的问题。当工作的粒子数极高的优化球模式推荐。

Custom Objects

自定义对象

The Custom Objects mode allows you to drag drop objects that will be instanced throughout your particle setup.

自定义对象模式允许你拖动下拉对象，这些对象将在你的粒子设置过程中被实例化。

Distribution

分布

There are two options for distribution, Sequential & Random. Sequential will distribute our objects in a logical order. As you can see in the example below we have 3 different custom objects; Pyramid, Sphere, and Platonic. So the first 3 particles that come out will be a Pyramid, Sphere, and Platonic then repeat in that order every 3 particles. Random mode will randomly select through our custom objects for each particle and this will also allow us to use the Random Seed option as you can see in the example below.

有两个选择的分配，顺序和随机。顺序将按逻辑顺序分配对象。正如你在下面的例子中看到的，我们有3个不同的自定义对象: 金字塔、球体和柏拉图。所以最先出现的3个粒子是金字塔，球体，和柏拉图，然后按照这个顺序重复每3个粒子。随机模式将通过我们的自定义对象为每个粒子随机选择，这也将允许我们使用随机种子选项，你可以在下面的例子中看到。

 

Random Seed

随机种子

Used only in conjunction with Custom Objects and Random distribution, allows you to randomize the distribution even further.

仅与自定义对象和随机分布结合使用，允许您进一步随机化分布。
