Recently I found some free time to make a few tests in V-Ray and Rhino. My aim was to achieve as realistic fabrics as possible. Starting with leather was not pretty good idea, because I tried to draw a bump map by myself in Photoshop and it just looked bad.
Then I realized that it is almost impossible to get nice wrinkles using 200 pix PS brush, so I got some reference images from the Internet, stacked one above another in Photoshop layers and what I got was pretty nice bump map. I made a few test renderings, and just then after 9 attempts it looked good.
Big challenge in Rhino was to unwrap this set of simple NURBS surfaces to one and single UV map, to have a control over the model using the only V-Ray material. Fortunately, I was successful :)
For making these textures as optimized as possible, as a Diffuse and first Bump maps I used a single texture, which was even cropped and scaled down, therefore for the correct mapping of this fauteuil, You have to repeat both of these 10 times in both U and V directions (all set in V-Ray material settings).
Of course, this 3D model with all textures is available for free from my website, FlyingArchitecture.com. Click here to download this “fauteuil bas”

Let me know in the comment area below, what do You think about the final result, or even better – give me some suggestions about Your workflow for objects like this. I will be very grateful :)
