Name

The shader’s name. Enter any name you like, or leave the default.

Texture Space

Object Selection: When multiple objects are selected, defines whether changes are applied to all objects or a specific one. This control updates automatically as you select objects in the scene, as long as the property editor is not locked.

Property Selection: Lets you choose a Texture Support to use. If no texture support has been defined, you can create one by clicking New. If a texture projection is already defined, you can edit it by clicking Edit.

Projection Method

Defines how the image will be projected on the object(s).

Disabled:

UV: Projects the texture along the U and V.

XY: Projects the texture on X and Y coordinates only.

XZ: Projects the texture on X and Z coordinates only.

YZ: Projects the texture on Y and Z coordinates only.

Spherical: Surrounds the object with a spherical mapping across the whole surface with some distortion.

Cylindrical: Projects the texture as though it is a cylinder wrapped around an object.

Lollipop: Similar to spherical but the texture is more “pinched” at the poles.

Space Transformation

Unchanged: As is.

Object: The texture is mapped according to the object’s center (0,0 coordinate), and the texture will move with the object.

World Space: The texture is mapped to the scene’s 0,0 coordinates. The texture will remain stable, even if objects move, as though the object is “swimming” in a texture. As long as the object does not move, the texture will remain constant.

Camera Space: The texture is mapped relative to the camera’s center. In this coordinate system, the camera is the center of the “world,” with an up vector, looking toward the negative Z axis. The result resembles an image projected from a camera. The texture will move with the camera and will be affected by any scaling, rotation and translation.

Screen Space: The texture is centered onto the camera, projected like World Space, but the Z value is set to 0.

Light: The texture is centered onto a light, projected like World Space.

Triangle Intersection

At Intersection Point: The shader will use the coordinates where the ray hits the triangle to calculate the texture space.

Vertex 1, 2, 3: Will return the coordinates at the selected vertex of the triangle. For example, set to vertex 1, on a normally textured object, will lead to the same UV coordinate being used over the entire triangle.
