very nice, is the leather part detailed in ZBrush? how did you do the stitching? by distributing single stitch along the path or opacity map inside shader? How many polygons?

The model was made in 3ds max, all made of poly modeling. Stitches made with geometry and multiplied along the way, on the surface. I added ties on the little hairs, the Hair and Fur modifier. The model has correct texture coordinates, which allows to correctly configure the materials.

The model of a chair without stitches: 15564 polygons
The model with the stitches: 137900 polygons

Nice detailing, but for the stitching it's more optimal to use single spline and imitate the stitching with opacity map, saves ton of geometry weight.

Looking for what purposes )
If the General plans, then Yes, but if to large, I prefer geometry )

The render with materials applied looks awesome already!

Thanks maru! )

What can you say about this option?

Personally I prefer the previous leather. The new one looks more like concrete. ;)

Texture detail on leather is great (on both), but they lack speculars to my eye. Almost like you clamped your reflection channel (which ideally, you wouldn't use) with aggressive bitmap which only should go to glossiness.

Of course, without compression of highlights is better, but not always it turns out difficult to achieve in bright places (not in this case)
Without compression looks in more detail )
