Houdini Spawn by distance
If you’ve used 3ds max PFlow then you are familiar with this important feature, a self explanatory title it helps you create trail of particles with a fixed predefined distance. This feature is also present in Cebas Thinking particle as (TrailBorn).

I added a couple of features and parameters for you to control:

• Distance.
• Inherit Velocity.
• Life.
• Id (a hidden one but will help you sort trails by their parent), I color coded them in the video.
• Trail Group, so you can isolate them later.

The possibilities are endless since I used a vex code, I tried it with different scenarios and it survived. Sometimes it misses a step or two not sure why and I couldn’t replicate this problem, also some fast moving parents requires you to up the dop substeps in this video I set it to 5, the system will take this into consideration so don’t worry no need to modify the code.

This technique relies on the seeds (parent particles) to have a velocity attribute so it can calculate the path right, sometimes when you add a drag force the results will be affected abit.

胡迪尼距离繁殖
如果您使用过3ds max PFlow，那么您熟悉这一重要功能，这是一个不言自明的标题，它可以帮助您创建具有固定预定义距离的粒子轨迹。这一特征也出现在Cebas思维粒子（TrailBorn）中。
我添加了一些功能和参数供您控制：
-距离。
-继承速度。
-生活。
-Id（一个隐藏的Id，但可以帮助您按父项排序），我在视频中对它们进行了颜色编码。
-追踪小组，这样你可以稍后隔离他们。
自从我使用了一个烦人的代码，我在不同的场景下尝试了它，它就活了下来。有时它会漏掉一两步，不知道为什么，我无法复制这个问题，而且一些快速移动的家长要求你在这个视频中升级dop子步骤。我将其设置为5，系统会考虑到这一点，所以不用担心，无需修改代码。
该技术依赖于种子（父粒子）具有速度属性，因此可以正确计算路径，有时当您添加阻力时，结果会受到影响。
