With these, UVs, individually or as part of a larger collection, can be manipulated relative to the square workspace grid that represents the area occupied by an image, the Texture Space, it’s this area that determines the ‘what’ and ‘where’ placement of UVs with respect to any image mapped to an object. Each has a corresponding UV Selection Mode so the different elements can be selected and manipulated individually, or as part of a larger group or collection, using the Move ( G), Rotate ( R) and Scale ( S) tools available in the UV Editor Toolbar ( T) down the left side of the editor. a Vertex, Edge, Face, and UV editing specific, Island. UV maps are edited, manipulated and managed in the UV Editor, or UV Editing Workspace, using the same basic compositional and selectable elements as a mesh in the 3D Viewport, i.e. UV Editing Workspace showing a simple (default) Cube mesh object UV Unwrapped (right) to create a UV Map (left) ready for an image to be mapped so it appears in the 3D Viewport. This map is the objects UV Map, the process of creating it, UV Unwrapping.ĭesign note: although UV Unwrapping and UV Mapping are technically distinct terms they are often used interchangeably to refer to the same process mapping or preparing an object for image assignment. In other words, for a mesh to appear as though its made from wood, a 2D map of the object is needed for the wood texture to appear correctly positioned on the mesh when viewed or rendered. UV Maps are essentially two-dimensional representations of three-dimensional structures that have been processed, or unwrapped, to form an otherwise flat layout or map of an object to which an image or material can be assigned. Important: see UV Editing (Workspace) Basics for more on UV editing generally. For correct display this means objects need to be UV Unwrapped, and images UV Mapped to those unwrapped surfaces, before anything is seen, requiring a basic understanding of UV Maps. The dominant grid is the continuous grid with the largest area.For newer versions of Blender UV Maps play a more important role because, with the removal of the now obsolete Blender Render engine, textures and materials are not rendered on surfaces without them. unwrap the rest of the selected vertices pin grid area with largest area and unselected vertices Align the grid area with largest area to a grid like uv layout Filter out the grid area with the largest area Filter out continuous areas with gridlike topology Supporting multiple grid areas are not important at the first implementation of the operator The dominant grid is the continuous grid with the largest area. The topology that is not built in a grid like fashion (selected/green), or is not part of the contineous grid like topology with largest area, will be adjusted to fit nicely to the rectified UV’s. The topology that is built in a grid like fashion (selected/orange) is aligned to the U and V axis. Selected UV island shoud be automatically aligned to a to U and V as much as possible for the topology which is built in a grid like fashion
