Melt
Updated: 4 Dec 2023
Smooth a procedural.
Melt
Method #
This node smooths the shape a procedural in 3D space, much like how a blur smooths an image in 2D space.
Parameters
These properties control the 3D transforms of the node. Transforms will generally be inherited by child nodes, although they can be ignored through the Inherit Transform Channels attributes.
Parameter Details Position X The objects position along the local x-axis.
Position Y The objects position along the local y-axis.
Position Z The objects position along the local z-axis.
Rotation Heading The objects rotation around the local y-axis.
Rotation Pitch The objects rotation around the local x-axis.
Rotation Bank The objects rotation around the local z-axis.
Scale X The objects scale along the local x-axis.
Scale Y The objects scale along the local y-axis.
Scale Z The objects scale along the local z-axis.
Control the inheritance of the transforms from the parent.
Parameter Details Position Toggle inheritance of the Position from the parent.
Rotation Toggle inheritance of the Rotation from the parent.
Scale Toggle inheritance of the Scale from the parent.
World Position Only Inherit the world position from the parent only, rotation and scale will be ignored. Overrides above properties.
Inherit Time Toggle inheritance of time from the parent.
These properties control the core behaviours of the node.
Parameter Details Distance Offset Offsets the distance field values, causing the generated distance field to expand of contract.
CSG Mode These options change how a this procedural node combines with the existing of the procedural system.
- Replace : Replaces the previous procedural system with a new procedural shape.
- Union : Simply combines both the new procedural shape and the existing procedural system.
- Intersection : Interesects the new shape with the shape before.
- Subtract : Subtracts the new procedural shape from the existing procedural system.
- Blend : Blends between both the new procedural shape and the existing procedural system, driven by the CSG Blend Weight.
- Union Blend : A combination of union and blend which tries to preserve both objects more, with the blending being driven by the CSG Blend Weight.
- Smooth Union : The new procedural is added to the old, and smoothing (driven by the CSG Blend Weight) is applied to the outcome.
- Smooth Subtract : The new procedural shape is subtracted from the existing procedural system, and smoothing (driven by the CSG Blend Weight) is applied to the outcome.
- Offset : Blends one procedural ontop of the other another withing the area of the original procedural system.
- Custom Code : Allows you to enter your own expression code.
Filled Mode Thickness of the Shell wall, when Filled Mode is set to Shell.
Shell Thickness Thickness of the Shell wall, when Filled Mode is set to Shell.
Grid Width/Height/Depth Size of the SDF Grid used for generating this effect.
CSG Blend Weight How much the new procedural blends with the old procedurals, depending on the CSG Blend Weight.
Material Colour Modify the colour for the procedural material.
Custom CSG Code Type your Custom code here, using the HLSL language. Read more on Editable Code.
Iterations How many iterations of the melft function are run.
Error Tolerance Expands the allowable values for generating the Distance Field. Higher values often get rid of jagged edges and odd rendering behaviours, but with decreased performance.
Use Colour Affect the colour of the generated procedural system. only functions with ‘Generate Colours’ enabled in some Procedural Render nodes.
