VRayTexFalloff produces a gradient texture based on the angular falloff of the the surface of the geometry to which the texture is applied. The resulting map can simulate the falloff of opacity, reflection, and refraction for surfaces where these properties vary depending on the surface's angle to the camera, such as curved glass or water.
To create the texture, VRayTexFalloff starts with two colors, usually black and white. Placement of these colors on the surface is based on the Falloff Type and Falloff Direction selected. The remainder of the map is generated as a gradient between these two colors, with a gradual falloff between the colors.
For the example shown on the right, VRayTexFalloff is used in the Diffuse channel of a VRayMtl. The Falloff type is set to Perpendicular/Parallel with the Falloff Direction set to world Y Axis. Solid colors ofbright orange and dark green are used for the Front Color and Side Color parameters.
