Bump Shader Properties Shader Property Description Amplitude Drag the slider to the right, or enter a value if an edit field is available, to increase the relative differences in height of the indentations Blend Drag the slider to the right to increase the amount of blend at the edges of the pattern Brick Amplitude Specifies the height of the bricks above or below the surface Cast Amplitude Drag the slider to the right, or enter a value if an edit field is available, to increase the amplitude of the surface displacements (bumps) which form the irregular casting pattern Cell Amplitude Drag the slider to the right to increase the height of each cell in the pattern Center Blend Drag the slider to the right to increase the size of the blend between the dimple sphere and the surface Center Depth Enter the distance beneath the surface of dimple sphere centers; this value should be less than the Radius value Cloud Amplitude Specifies the height of the cloud regions above or below the surface Cubes Amplitude Specifies the difference in height between the cubes Curve Amplitude Drag the slider to the right to increase the number of curves in the edges of the cells in the pattern Curve Detail Drag the slider to the right to increase the level of fine detail in the grooves between the cells, providing a more creased appearance Curve Frequency Drag the slider to the right to increase the wiggly nature of the edges of the cells Dent Amplitude Drag the slider to the right, or enter a value if an edit field is available, to increase the amplitude of the indentations which form the irregular casting pattern Dent Scale Scale values above one make the indentations appear larger Dent Threshold Drag the slider to the right to increase the relative contributions made by the surface displacements and indentations Detail Drag the slider to the right to increase the level of fine detail Fold Amplitude Drag the slider to the right to increase the amplitude of the large-scale folds or wrinkles in the surface Fold Detail Drag the slider to the right to increase the level of fine detail for the large-scale wrinkles in the surface Fold Frequency Drag the slider to the right to increase the number of large-scale wrinkles in the surface Graininess Drag the slider to the right to increase the graininess of the paving Grain Scale Drag the slider to the right for larger grains Grain Size Scale values above one increase the size of the grains Height Sets the height of the fragments Height Variation Drag the slider to the right to increase the variation in height across the surface Height Variation Scale Drag the slider to the right to increase the size of the height variations Height Noise Drag the slider to the right to increase the variation in grain heights, making some grains taller than others Height Noise Scale Scale values above one increase the size of the grain height variations; values less than one decrease the size Irregularity Drag the slider to the right to increase the irregularity of each cell that makes up the pattern, or to the left to make the cells more square Mortar Center Height Specifies the height of the mortar joint centers above the surface Mortar Edge Height Specifies the height of the mortar edges above the surface Mortar Height Variation Drag the slider to the right to increase the variation in height across the surface Mortar Height Variation Scale Drag the slider to the right to increase the size of the height variations Mortar Irregularity Drag the slider to the right to make the mortar joints less straight Mortar Size Specifies the size of the mortar joints between the paving slabs or tiles Shape Smoothness Drag the slider to the right for smoother paving shapes Shape Variation Drag the slider to the right to increase the irregularity of the paving shapes Slab Size Specifies the average size of the paving slabs or tiles Radius Values between zero and one define the radius of the dimple spheres Radius(tread plate) Enter the fractional radius of cylinders and spheres that make up the tread plate pattern; a lower value creates long, thin patterns (Range: 0.0 – 1.0) Ring Amplitude Specifies the height of the rings above or below the surface Ring Height Specifies the height of the wood rings above or below the surface Rough Amplitude Drag the slider to the right to increase the amplitude of the bumps in the surface Rough Detail Drag the slider to the right to increase the level of fine detail for the bumps in the surface Rough Frequency Drag the slider to the right to increase the number of bumps in the surface Scale Scale values above one make the pattern larger; values less than one make the pattern smaller Separation Enter the distance between the centers of adjacent dimple spheres Sharpness Drag the slider to the right to increase the abruptness of the transition between the peaks and troughs of the displacements Smooth Min / Max Drag the slider to the right to change the smoothness of the cell edges Spot Amplitude Specifies the height of the spots above or below the surface Stripe Amplitude Sets the height of the stripes above or below the surface Vein Amplitude Specifies the apparent height of the bumps Wood Height Specifies the height of the wood above or below the surface
