... only small update

it is better to use for Octane render (ver. 4.04) mesh export "Quads & Triangles" with CHECKED "Weld vertices along edges" (MoI ver.3).

This configuration generate smaller file, as Michael mentioned, and "Weld vertices along edges" allows to use function Rounded edges in Octane:



... without checked "Weld vertices along edges" function rounded edges doesn't work correctly:



Function Rounded edges helps to render more realistic pictures without needs to edge filleting in CAD programs.
