3D Render - Match to a Real Object
Object - Teacup
Using a DSLR camera to take multiply photos of the object's decoration, pay extra attention to avoid any highlight and reflection.
These pictures are then imported into Adobe Photoshop for further adjustment and alignment. "Wrap" tool under "Edit" - "Transform" is very helpful when aligning a series of pictures into flat surface.
The aligned patterns are then color corrected, and clean up into a set of asset images with transparency alpha channel.
The teacup reference pictures were imported into Autodesk Maya as image plane. Teacup model was made using basic polygon modelling tools.
Textures are imported into Autodesk Mudbox, and paint on teacup model using projection and stencil tool.
Then, multiple texture layer were painted, included Diffuse Color, Specular Color, Glossiness, Specularity and Bump.
