PyroCluster Tips and Tricks
Ever since computers have been used to create images and animations, artists and animators have been on the hunt for more computing power.
自从计算机被用来制作图像和动画以来，艺术家和动画师就一直在寻找更强大的计算能力。
It can be easy to bring a renderer to its knees, especially when using particle systems. In the following we will give you a few tips on how to more efficiently calculate PyroCluster effects.
它可以很容易地使渲染器的膝盖，尤其是当使用粒子系统。在下面我们将给你一些关于如何更有效地计算 PyroCluster 效果的提示。
Reduce the number of particles!
减少粒子的数量！
PyroCluster works best with a particle count of 200 to 600. Instead of increasing the number of particles, increase the size of the puffs and their density. In most cases, this should do the trick. You only need to increase the number of particles when animating fast movement or diverse particle systems.
当粒子数在200到600之间时，PyroCluster 效果最好。与其增加颗粒的数量，不如增加气泡的大小和密度。在大多数情况下，这应该可以解决问题。你只需要增加粒子的数量时，动画的快速运动或不同的粒子系统。
我需要更快地看到结果！
If you want to fine-tune your particle system, go to the Volume Tracer settings. Here you can adjust your particle system to optimize rendering speed. Changing just a single setting can save loads of time. This magical setting is the use distance setting. Increase its value as much as possible without causing render quality to suffer. Rendering can be increased by up to 100 times (or more)!
如果你想微调你的粒子系统，去体积跟踪设置。在这里你可以调整你的粒子系统来优化渲染速度。只改变一个设置可以节省大量的时间。这个神奇的设置是使用距离设置。在不影响渲染质量的情况下尽可能地增加它的值。渲染可以增加100倍(或者更多) ！
We suggest manual splitting in order to be able to ascertain the most effective value. Start with what you think is the highest acceptable value (e.g., 10). The image will probably look terrible - no detail at all. Now reduce the value to 5 and take a look at the result. Depending on the result, increase or decrease the value to get the best result.
我们建议人工分割，以便能够确定最有效的价值。从你认为可接受的最高值开始(例如，10)。这张照片可能看起来很糟糕——一点细节都没有。现在将值减少到5，并查看结果。取决于结果，增加或减少的价值，以获得最佳的结果。
You can achieve even faster render results by increasing the ray depth limit.
你可以通过增加光线深度限制来达到更快的渲染效果。
