Grid size

I’m testing out renders in LuxBlend, and I was wondering how big one blender unit is? Since there’s nothing to specify what size cube/plane/sphere you create, what are the defaults? What size do the grid markings represent? Basically, anything that could help me get things to a ‘realistic’ size would be great.


1 grid unit = 1 blender unit (BU) = whatever you want it to be.

Generally for things like the physics engine or some external renderers etc it is best for 1 BU = 1m but if you’re not bothered with anything that needs explicit units use what ever is most appropriate fomodel you’re making.
