- | ====== Position Maps ====== | ||
- | The Position maps within Knald are generated from high to low polygonal meshes via [[the_baker_knald_1.1|The Baker]] & contain RGB information which correlates to specific positions found on the High Poly mesh. When multiple channels are rendered they form a volumetric gradient, with each pixel within the map pointing to a unique area of the mesh (no two values/colors within the position map contain duplicated positional data). They are viewable in the Position tab when selected. | ||

- | **Normalized:** The toggle between Uniform & Non-Uniform normalization. This can be changed at any time without the need to re-bake. | ||
- | |||
- | * **Uniform:** Applies uniform normalization to the resulting position map. | ||
- | * **Non-Uniform:** Applies non-uniform normalization to the resulting position map. | ||

- | |||
- | **Use Median Anti-aliasing** This check box is a toggle between Average & Median anti-aliasing. | ||
- | * **Average:** Results in a smooth blending of values between contiguous elements. | ||
- | * **Median:** Results in a hard edge between values of contiguous elements. | ||
- | |||
- | // | ||
- | |||
- | **Invert:** Inverts the Position map. | ||
- | |||
- | **Render Axis:** Allows the choice of which axes you wish to render position information for. | ||
- | |||
- | * **X:** Enables rendering of position information on the X axis (left/right). This data is contained within the red channel of the resulting texture. | ||
- | * **Y:** Enables rendering of position information on the Y axis (up/down). This data is contained within the green channel of the resulting texture. | ||
- | * **Z:** Enables rendering of position information on the Z axis (front/back). This data is contained within the blue channel of the resulting texture. | ||
- | |||
- | **Axis Rotation:** Allows the independent axis rotation of rendered position information. | ||
- | |||
- | * **X:** Rotates the Position map on the X axis (red channel). | ||
- | * **Y:** Rotates the Position map on the Y axis (green channel). | ||
- | * **Z:** Rotates the Position map on the Z axis (blue channel). | ||
- | |||
- | Any combination of axes can be rendered as per the users wishes. | ||
