Transforms UV texture coordinates on the source geometry.
The UV Transform operation transforms UV texture coordinates on the source geometry. Unlike the UV Edit operation, UV Transform supports animation of UVs.
UV Transform will automatically detect whether the input geometry uses point or vertex UV attributes, and will affect these attributes appropriately.
3D transforms are allowed in the UV Transform operation, as the UV attribute is actually 3 coordinates: U, V, and W. When used interactively, translates and scales are along the U/V axes while rotations are about the W axis.
Using UV Transform
Click the
UV Transform tool on the Texture tab.
Note
You can load the texture image as the background in your UV viewport to easily view edit changes.
Drag the verticies using the UV Transform handles to to move the UVs.
Parameters
| Group | Subset of geometry to apply current operation to. |
| Group Type | The type of elements referenced in the Group field. |
| Transform Order | Order in which transformations occur. |
| Rotate Order | Order in which rotations occur. |
| Translate | Amount of translation along uvw axes. |
| Rotate | Amount of rotation about uvw axes. |
| Scale | Non-uniform scaling along uvw axes. |
| Shear | Amount of shearing. The three values represent U on UV plane, U on UW plane, and V on VW plane respectively. |
| Pivot | Local pivot point for transformations. |
| Pivot about Group Centroid | Set the pivot to the center of the input group. |
| Soft Radius | Area of influence. |
| Soft Type | Type of rolloff function. |
| Tangent Angles | Angles of the cubic rolloff function’s tangents. The first value applies to the tangent farthest from the source point, the second applies to the tangent closest to the source point. |
| Kernel Function | Metaball kernel to use when rolloff Type is “Meta-ball” |
| Metric | Measure of distance to use when performing a soft transform. |
| Ignore Point Connectivity | Affect only points connected to the points in the group, or all points within the radius. |
| Ignore UV Connectivity | Affect only vertices connected to the vertices in the group as seen in the UV viewport. |
