Sorry, but when converting a sphere in 1.40, got:

Loading  pydough.geometry_export

Loading  pydough.geometry

Loading  pydough.hair

Loading  pydough.from_poser

Loading  pydough.to_lux

 

LuxPose Version alpha 1.40, exporting files to /Applications/Poser 8/Runtime/Python/poserScripts/luxrender/toLux/poser/poserscene_alpha 1.40.lxs

 

Using sampler metropolis

Using integrator bidirectional

Using accelerator kdtree
