The Size property determines the size of the flame particles. It must be in the range of [2, 30]. Unlike
ParticleEmitter/Size, the actual size of the flames will not match 1-to-1 with the equivalent size in studs; it is somewhat smaller.
To make your environment more cohesive, try adding a
PointLight as a sibling to the
Fire object. Set the
PointLight/Range proportional to this property so that larger flames produce more light.
This code sample adds
Fire to all
BasePart in the
Workspace named “Torch”.
