Type – Specifies the type of gradient ramp to create:

Four corner – A gradient that transitions linearly between colors assigned to each corner. 
Box – A gradient with a box radial transition.
Diagonal – A gradient with a diagonal transition.
Lighting – A gradient based on the light intensity.
Linear – A gradient with a simple linear transition.
Mapped – Specifies a map to use as a gradient.
Normal – A gradient based on surface normals and the camera.
Pong – A gradient with a diagonal transition that repeats in the middle.
Radial – A gradient with a radial transition.
Spiral – A gradient with a circular transition.
Sweep – A gradient with a linear sweep transition.
Tartan – Creates a gradient with a plaid pattern.
Position – Allows the user to specify a Gradient Position.

Gradient Position – Specifies the position of color in the gradient that is returned when Type is set to Position.

UV Name – The name of the UV channel that is used.

Repeat U – Multiplier for U values.

Repeat V – Multiplier for V values.

Coverage U – U values are remapped to 1.0.

Coverage V – V values are remapped to 1.0.

Translate Frame U – Translates the frame in U direction after applying rotate_frame (and before wrap, coverage, clamp).

Translate Frame V – Translates the frame in V direction after applying rotate_frame (and before wrap, coverage, clamp).

Rotate Frame – Rotates the frame after applying UV noise.

Rotate UV – Rotates the UVs after mirroring.

Offset U – Offset added to U before mirroring (after wrap, coverage, clamp).

Offset V – Offset added to V before mirroring (after wrap, coverage, clamp).

Noise U – Noise magnitude multiplier in U direction.

Nose V – Noise magnitude multiplier in V direction.

Mirror U – When enabled, every other tile outside the [0;1] range is mirrored in U.

Mirror V – When enabled, every other tile outside the [0;1] range is mirrored in V.

Wrap U – When enabled, U values outside the [0;1] range wrap back to [0;1].

Wrap V – When enabled, V values outside the [0;1] range wrap back to [0;1].

Stagger – When enabled, tiles in the V direction add +0.5 to the U value for a 'staggering' effect.

Projection Camera – Selects a camera.

Projection Camera (LOP)Same as Projection Camera parameter but for use in the LOP context.

Fit Fill – Specifies how the projection is fitted.

Fit Fill – Fitted to fill the space.
Horizontal – Fitted horizontally.
Vertical – Fitted vertically.

Fit Type – Specifies the type of fitting to use:

U / V Angle – Specifies the U / V mapping angle.

Film Gate W / H – Specifies the width / height of the film gate.

Hide Backface – Determines whether to project on back faces of polygons.

Hide Occluded – Determines whether to project on occluded points when using the Perspective Type.

Object Space – When enabled, the projection is applied in the object space of the currently shaded geometry.

Mapping Type – Specifies the type and shape of the texture from the following: Spherical, Angular, Cubic, Mirror Ball, Screen, Spherical (3ds Max), Cylindrical (3ds Max), Shrink Wrap (3ds Max), and Spherical (V-Ray).

Horizontal Flip – Flips the environment horizontally.

Vertical Flip – Flips the environment vertically.

Horizontal Rotation – Specifies the horizontal rotation (left and right).

Vertical Rotation – Specifies the vertical rotation (up and down).

Texture Rotation – Specifies the texture rotation.

Wrap U – If true, U values outside the [0;1] range wrap back to [0;1]. You can choose between the No Wrapping, Wrap and Mirror Tile options.

Wrap V – If true, V values outside the [0;1] range wrap back to [0;1]. You can choose between the No Wrapping, Wrap and Mirror Tile options.

Wrap X – If true, X values outside the [0;1] range wrap back to [0;1]. You can choose between the No Wrapping, Wrap and Mirror Tile options.

Crop U / V / W – Enables or disables cropping in the U / V / W direction.

DUVW Scale – Specifies an additional scale factor for the texture derivatives.

Ground – Enables ground projection of the texture.
