Terracotta tile floor "Vintage Handbaked"

Full procedural material for vintage handbaked terracotta hexagonal floor.

It usually looks better on a real floor than on the preview scene :

This uses quite strong deplacement and needs a lot of polygons to look right.

Recommended values for a 10cm x 10cm UV tiling on a 10cm x 10cm grid mesh :

<normal_smoothing> : false
<max_num_subdivisions> : 8
<view_dependent_subdivision> : true
<subdivide_pixel_threshold> : 0.005
<subdivide_curvature_threshold> : 0.01
<subdivision_smoothing> : false
<displacement_error_threshold> 0.00002

Bump only version coming soon...
