Decal Scatter

Short Description

Scatter decals on meshes.

Description

The Decal Scatter tool allows users to scatter decals over meshes, enhancing the visual details of 3D surfaces. It provides extensive customization options for scaling, density, and masking to achieve diverse effects based on the user's needs.

Properties

Base Properties

• Surface: Meshes to scatter on.

• Decals: Decal assets to scatter.

• Density: Scatter density.

• Min Scale: Minimum scale for random scale.

• Max Scale: Maximum scale for random scale.

• Surface Align: Adjusts the alignment of the decals to the surface.

• Depth: Depth of decals.

• Scale: Default extent of decals in cm.

• Sink: Pushes your instanced objects downwards, which is very practical for trees.

• Max Count: Maximum count of scattered decals.

• Seed: Random seed for variability.

Feature Masking

• Slope Mask: Masks objects by the angle of the underlying surface area under them.

• Min Height Mask: Minimum height at which objects should be clamped.

• Max Height Mask: Maximum height at which objects should be clamped.

Noise Mask

• Breakup: Controls the intensity of the noise/breakup.

• Breakup Scale: Frequency of the noise mask. This basically controls the scale of the noise.

• Smoothness Noise: This value controls how sharp/soft the noise mask is.

• Warp Noise: Deforms the noise mask, which can result in some really interesting swirly mask shapes.

• Noise Scale Multiplier: Multiplier for scaling noise effects.

• Noise Scale X: Controls the scaling of noise in the X direction.

• Noise Scale Y: Controls the scaling of noise in the Y direction.

• Noise Scale Z: Controls the scaling of noise in the Z direction.

Border Masking

• Border Offset: Masks the scattered objects along the surface's borders.

• Border Min: Minimum distance offset from the border mask value.

• Border Max: Maximum distance offset from the border mask value.

• Border Noise: Applies a noise on the border mask.

• Border Sampling: A higher value results in more precise border masking, but at a heavier cost.

Proximity Mask

• Proximity: Proximity meshes ensure that only scattered objects nearby are kept.

• Distance: Controls the proximity distance.

• Sampling: A higher value results in more precise proximity masking, but at a heavier cost.

Object Masking

• Objects: Samples objects near the meshes using raytracing for proper mesh proximity masking.

• Distance: Controls distance of the padding we add to the inside mask.

• Keep Inside: When set to true, ensures that we only keep what's inside of our meshes.

• Invert: Inverts the mask.

Rotation Properties

• Uniform Angle: Adjust the spin of the decals. Has no effect if 'Spin' is turned on.

• Spin: Give random spin to decals, which ensures great rotation variation.

• Rotation Jitter: Additional random spin.
