High resolution Croissant Sofa.
The above presentation images are rendered using the Vray version (HDRI is included).
The materials assigned to the model use the following textures: 1 1024x1024 diffuse and 1 2048x2048 bump map for the pillows; 3 diffuse textures for the frame (512x128, 64x64 and 512x256).
The model doesn't need any smooth modifier, since it's already modeled at the final resolution.
Note: the pillows use 2 texture channels, the first one with packed uv's for the bump/displacement map, and the second one with overlapping uv's for the tileable diffuse texture; in the OBJ format, due to its limits, the second channel isn't available.
