A while ago I made an attempt at creating an effect of kicking dirt. After reading this, I believe it may be possible to adapt that technique in creating a "bullet hitting the ground" effect. My attempt at creating dirt being kicked up can be found here
, along with steps on how to create it below.
The video found here
is an example of what this effect could look like when altered to resemble a bullet hitting the ground. As I write the steps for the first effect, I will include a variation of the steps that I took to create the second effect.The settings and steps to create these effects are as follows
Import the textures "Smoke_1
" and "Smoke_2
" that come standard with EffectsLab Dv. (If you require instructions on how to find these textures, and how to import them, please feel free to ask) 2)
Make sure the "Texture Button" is set to "Single
" and not
"; this is because you are not dealing with an animated texture, so you will not achieve the desired effect if you are selected on animated. I am not sure how this may affect this effect, so it is best to stay on what is used in the videos above. Although the default setting is "Single", be sure to check by locating the "texture button"
In both of the example videos above the emitter is set to its default, which is "Emitter Point
", "Free from origin
". This means that the particles will be emitted from one single point on the canvas, and are enabled to go about their own movement once emitted.4)
- For these example clips, max particles does not need
to be set very high. If you watch the videos, the effect does not last for a very long period of time, and there for, does not need many particles to be created at any given time. This is also not generally a big effect in most cases anyway. For the dirt example clip it was set to approximately 4000
, and that is more than enough for both.Particle Rate
- For the dirt example I used a particle rate of 50
. As for the dust example, a particle rate of 200
was used.Life Time
- The "Life Time" determines when each particle will disappear. In the first example life time was set to 61
. In the second example life time was set to 25
. Although this can be changed if you like, changing this too much can drastically change how the effect will play out. It is up to you to see how the effect is changed.Emitter angle
- The rotation wheel is used to choose the angle from which particles are ejected from the emitter. The first and second examples are set to almost the direct top. The numbers are:
- "Absol." -8.76
- "Relative" -8.76
- "Turns" -0.02
- This can actually have a big impact on how it appears the "dirt" or "dust" spreads (flies), and how it lands. To achieve the exact look in the first example clip, you want this to be set to 54
. For the second clip, you will want this value to be set to 178
- This is really a personal preference setting. Going much bigger then the example clips may change the overall look to the effects, and may make you have to change other settings to compensate. Both the first, and second video clips were set to 0.20
: In the examples, new particles are being created in front of the existing ones. To do this, locate "Draw new particles behind" found in "Particle Creation" and change it to "Draw new particles in front". 5)
".Color Gradient/Opacity Gradient
- As you can see, this is different for both the clips. This will basically just depend on the surface you are adding the effect to, so I can't really tell you which way to go with this one. If you are not sure how to change the color gradient, I would suggest reading the manuals as soon as you can, they can prove very helpful.
Again, if you have little to no experience using this gradient, I would recommend you refer to the manuals. If you can not locate your manuals, please ask, I would be happy to guide you to them. For now I will quickly tell you what to affect, and the percent of opacity to add to each tab. These are the values you want to affect
For the first clip, start by selecting the tab on the left
of the opacity bar
(by left clicking it) and set the value
with the slider tab at the top. You can see what the value is at the right of the gradient window. Now select the tab on the right, and set the value to 40%
. For the second clip, set the left tabs value to 4%
, and the right tabs value to 5%
- Both the dirt, and the dusts speed randomizer is set to 1.00
. Size Randomizer
- Size randomizer is set to 0.90
in both of the clips as well.6)
This allows for the particles to behave more like dirt or dust, which eventually tend to fall, and do not just continue being pushed in one direction. In the first clip, the gravities direction and strength are set to:
- "Absol" 230.97
- "Relative" -129.03
- "Turns" 0.64
- "Strength" 0.16
The direction and strength for the second clip are set to:
- "Absol" 172.81
- "Relative" 172.81
- "Turns" 0.48
- "Strength" 0.02
Now, all of the parameters are set, we are almost done. You may be wondering why the effect in the example clips does not keep emitting. This is because the emitter has been turned off. For the first clip, advance one frame, then turn off the emitter on that frame. Do this by looking to the right under "Particle Creation". Change the emitter from "Emitter On" to "Emitter Off" by clicking the green button. The emitter will now stop ejecting until turned back on, but the particles previously emitted will continue to live out there life time.
In the second clip, I didn't start the effect until the seventh frame in. I then created the effect, advanced two frames, then turned off the emitter (which would mean I turned it off on the third frame of the effect). The same idea as the dirt example clip, but just a little different.
That covers how I accomplished those effects. If you have any questions, or if there is an area that I did not cover, or simply does not make any sense, please let me know, and I will try to clarify. I hope this is close enough to what you are looking for ashman69erdude, or at least gives you enough to go off of in your efforts to create this effect.Note
