This shader is the same as the mib_lookup_spherical shader, except that it accepts one texture mapped on an infinite cube. This is useful for environment shaders.
| Name |
The name of the shader node displayed in the render tree. Enter any name you like, or leave the default. |
| point |
The view location. |
| dir |
The direction to sample. If connected to the mib_texture_vector shader, a select value of -10 is useful. If this is the null vector, the ray direction is used. |
| size |
The size of the box. |
| tex |
The texture to be looked up at the computed coordinate. One texture contains all six sides; it has six times the number of scanlines required for a single face, with the subtextures stacked in the following order, starting from the top and going down: -x, +x, -y, +y, -z, +z You can Edit the image clip, or get a New image clip from file or from source.
