Each segment of the model is modeled as a separate object (yet properly parented and grouped into single group for easier appending / linking).
Bounding dimensions (approx): 49 x 59 x 59 cm.
Materials: all procedural PBR, based on Principled / Emission shaders, thus widely compatible with modern PBR renderers. No texture files (raster images) used.
UV maps unwrapped.
HDRi environment map (En Suite, public domain) packed in .blend for more realistic reflections, as well as put into supporting items separately. See product imagery for additional environment lighting examples.
All imagery is done via Cycles / Filmic (Base Contrast profile), no post-processing.
