Catto is the player character of our indie game "Catto's Post Office" and he sleeps in a small cozy bedroom which used to be a storage room at the back of the post office. This was my first time using a particle system to create fine dust in the air to recreate the dustiness of storage rooms and it was such a fun experience as I find particle systems very interesting. At first my renders would not come out as expected and the dust particles were either too large, too saturated or just not showing up at all. I had to play around with the particle system settings and eventually found out that Blender Cycles doesn't render particle systems and so I rendered through Eevee instead. I'm excited to add this bedroom to our game and want to try experimenting more with particle systems for my future renders.
