Red Giant Software: Creating a Looping Particle System
The Red Giant Software program allows you to create a particle looping system, which can enhance your visual effects and help you achieve the impression you want. If you want to create this particle system to give the impression of rain or snow, you have to use 2 of the Red Giant products: the Starglow and the Trapcode Particular. Starglow will help you create a glow around the highlighted source. You can adjust the color map you want in order to achieve the desired result. You can use the particular effect on the footage you shoot from the camera. The effects you will create depend a lot on the original source you are feeding to Trapcode Starglow. Here is what you need to do to create the looping system.
Step 1: Start the Starglow Program
Import a footage file and apply Effect > Trapcode > Starglow. If you cannot see any change in the image, open the Pre-Process group and lower the Threshold value until you notice a change in the output. Now try and change the Preset pop-up to see the variety of different looks.
Step 2: Adjust the Glow
Using the Trapcode Starglow, you can adjust the glow properties for the particles you have. You should click on the Glow Sphere as particle type in order to activate the properties. You should then go to the Glow > Size control and set the pixel size of the glow. If you set high values, each particle will cover a larger area. The low values will make the particles dimmer, covering a much smaller area.
Step 3: Adjust the Opacity
Once you are done with the glow, you should adjust the opacity of the particle glow. The higher values here give you a solid outline, while the lower values will offer you a transparent glow. If you want to make the effect more impressive, you should apply high values.
Step 4: Adjust the Feather
Feather is associated with the glow softness; if you want to have a solid result, you should lower the values, but if you want the perimeter of your particles to be softer, you should apply higher values – the higher is 100.
Step 5: The Transfer Mode
In this step, you need to make the proper adjustments so as to compose the looping system and glow with the particles and the Glow sphere. Here is where physics come into game. The physics group can control the motion of the particles. You have to set several values and properties, such as Turbulence and Gravity and make the particles bounce on the other available layers of the composition.
Time factor is also very important because it enables you to take complete control over the looping rate. You can open the Physics Tab and click on time frame, adjusting the time the way it suits your effect needs. Adjusting time properly you can accelerate the movement of the particles or make them move in reverse. The key frame will allow you to control the simulation, beginning and finishing it whenever you want.
