Flicker Expression If you want to generate a curve with random values between 2 and 8 with a (low) frequency of 1 peak every 5 frames this is the formula: (random(1,frame*0.2)*6)+2 (random(seed,frame*frequency)*amplitude)+valueOffset If you want a curve containing random values between 0 and 1. (random(1,frame*1)*1)+0 simplified version : random(1,frame) Break it up rooftop bricks : break it up, some big, some small, less straight line, slight color variation fx expanding spell : don't expand like a circle, break it up, more starfish like, more organic fx spell trail dissipation : use wind to break up the straight line trail walls : add dirt, add moss, don't be too clean heat haze : break it up, some small, some big, some have some holes Framehold alembic how to framehold anim/cfx crowd alembic file? asset objects > load options tab > frame parameter default it $FF (frame number by default) clamp it by doing : clamp($FF, 1120, 1251) ie: clamp(val, min...
