Units and scale
The platform works in centimetres. Blender works in the units of your scene: metres, unless you changed the Unit Scale under Properties ▸ Scene ▸ Units.
You don't need to change anything. The addon converts between the two in both directions:
Positions and sizes of objects
Lengths in materials, such as displacement height and the real-world size of textures
The size and brightness of lights, so a light shines as brightly on the platform as in Blender
Lights from Blender 5 that use Exposure, Temperature, or have Normalize turned off arrive on the platform with the same brightness and colour.
