Important parts to read: the first two sections of instructions and the second part of notes and credits. The rest you can read if you want. I recommend the bottom of the instructions. It's some cool presets. Read the second to last part of the instructions to read about the superiority of pen. Move your mouse to the top of the screen to show options. Adjust the variable then click the flag so it can take effect. You can use this if you have an atmospheric game you'd like to improve (that means @2030). Works best with bitmap because pen "Why pen?" you might ask. Well, you can have a lot more particles. For cloning you can only have up to 300, while with pen you can have unlimited (but it will lag then crash, so maybe not...). But seriously? It works just fine at 3,000 particles. That's 10 times the clone limit. Cool presets: Particles 5,000, Size 2, Base Transparency 190. It's snow! Particles 50, Size 4, Base Transparency 255. It's fireflies! NOTE: For this one, decrease the blue in RGB to give a nice firefly yellow. Particles 5,000, Size 4, Base Transparency 225. It's a blizzard! DEFAULT VALUES. Dusty ambiance. Particles 200, Size 4, Base Transparency 150. It's @griffpatch's dust project!
