如何创建在After Effects中烟雾的影响

有几种不同类型的动画烟雾效果,你可以在After Effects中创建,并几种方法来创建它们。在本教程中,我要告诉你一个快速的方法来模拟一个密集的篝火晚会或烟囱冒烟,使用粒子游乐场。


第1步 - 应用粒子游乐场

First, make a new composition of 10 seconds or so, at whatever resolution you like - I'm working at 1280x720, as usual. Add a new black Solid (Command/Ctrl-Y), and make it the size of the comp. Apply Particle Playground to the comp (Effect > Simulation > Particle Playground) and set up Cannon as follows:

请注意,我感动大炮发射的比赛帧的底部,并设置零重力,使粒子将不属于正在排放后回落。另外请注意,我已经设置粒子的颜色为浅灰色。 (这些设置只是指引 - 与他们的实验,以建立不同类型的烟雾效果。)

第2步 - 添加高斯模糊

Next, add a Gaussian Blur (Effect > Blur & Sharpen > Gaussian Blur) to the Particle Playground comp. Set Blurriness to 15, and Blur Dimensions to Horizontal and Vertical.

第3步 - 添加蒙版,并使其在墙上


点击钢笔工具,绘制一个简单的2点的面具,在您的计算机窗口直接粒子流的权利。曲线稍微拖动的面具的处理,并拖动大炮流中心的最高点,所以行。 (Escape键。命中后,画第二点,使一个开放的面具)面罩应该是这个样子:


第4步 - 创建一个属性映射


添加一个新的固体您的比赛,在比赛一样大小,并运用斜坡的影响 (影响



第5步 - 应用属性地图

最后一步,再次选择粒子游乐场层,滚下来的持久化属性映射 twirly箭头,并设置使用层作为映射到您的斜坡前比赛。

其次,根据影响,地图设置为红色规模,最小值/最大值为0和25,分别 - 这将使粒子变大,因为它们在屏幕上流动起来,并因此使烟“clumpier”,因为它上升。然后设置地图绿色不透明,最小值/最大值,分别为1和0,如下所示:

确保您的地图绿色最小设置为1,最大为0(默认值相反) - 这将使烟雾粒子淡出他们的做法框架的顶部。

Hi Richard,
This looks like something you could also do in Motion. Any thoughts on how these two compare?
