To create a snowfall effect in Niagara, the first step is to create a new Niagara System asset and add a Particle Spawn module. Then, set the particle spawn rate and lifetime to control the density and duration of the snowfall. The next step will be to add a Particle Update module to apply gravity and wind forces to the particles, simulating their movement in the air. Finally, by using a Material module to add a snowflake texture to the particles and adjusting the colour and opacity I was able to add snowfalls into my scene.
A weight shift is when a character shifts their weight from one foot to the other, creating a natural sense of balance and movement. At our session, George told us about the importance of distributing the weight correctly and always keeping the centre of gravity in mind the way we can do that is by imagining a line through the middle of the pose and checking the balance of the positive spaces. Here you can see my planning and also the blocking of the weight shift animation.
