Blender Scene and Modeling Units

Post by Snowcarver »

Hi,

What units should I use to model the scene in order to get the correct lighting? Meters, Millimetres, Blender Units or not care?

I would hope that it doesn't matter as I'm used to work in centimeters. And just for clarification it would be nice to know if a "Unit Scale" other than 1 has any impact on rendering (I'm using 0.01).

1 Blender Unit = 1 meter in LuxCore.
Just like in Cycles, unit scale is ignored. So if you want parameters like f-stop in depth of field to work exactly like expected, use 1 Blender Unit = 1 meter. Otherwise you will have to do the conversion yourself.

Unless materials and lights in Luxcore aren't affected, I'm fine with using a Unit Scale of 0.01. If it's only about f-stop and DOF - I don't mind.
