Utility
Utility nodes remap the values depending upon the node’s algorithm.
Curve
Remap Value to custom curve.
- Fast Eval
- Use a custom multi-threaded formula for evaluating the curve.
- Curve
- The visible result of the function used to remap input values.
- Reload Curve
- Blender doesn’t allow for creating or saving of UI curves. In order to get a node as we have in NodeScapes we create an RGB Curve shader node in a hidden node group. If this node group or the source node is deleted, the curve in the NodeScapes node will disappear and reveal this button. Clicking it will recreate everything it needs to in order to have the curve again. It will also recreate the curve if the curve node had been executed previously.
Understanding the Curve Node
The curve node is just a graph. It takes the values (heights) and passes them through the curve. The curve is just a visual representation of a mathematical formula or function or func (y=x, y=2x, y=2x^2, etc.). So if we look at the example curve here we see that if we plug in an input value of 0.0 (y=func(0.0)) we will get an output value of 0.0 because where the x-axis equals 0.0 the y-axis also equals 0.0 on the curve (ex. 1 below). If we plug in 0.5 as the input value (y=func(0.5)) we get an output value of 1.0 because where the x-axis is 0.5 the curve is at 1.0 on the y-axis (ex. 2 below).
Example
Using a gradient node we can visualize the curve in the geometry.

Normal Mask
Results in a map of values from 0-infinity relative to how close each vertices' normal is to the target normal and the threshold value
- Clamp
- Values higher than 1 and lower than 0 are ignored and set to either 1 or 0 respectively
- Target Normal
- This is the large sphere in the node
- Click and drag to rotate the sphere in order to choose the normal value. Default value is a normal facing directly up, usually meaning a flat surface
- Show Normal Sphere
- Display the target normal as a sphere to easily rotate the normal
- When off the target normal is displayed as 3 float values
- Normal Picker
- Click a place on the object to choose the normal in that area
- Coordinates
- Connect the output of the nodes you’d like to use for creating a mask here
- Threshold
- How lenient to be when including normal values close to the targeted normal
- Falloff
- How far from the target normal + threshold value to fade out the mask

Vertex Edits
The 'Vertex Edits' node allows you to save manual edits to the geometry from Sculpt Mode or Edit Mode and keep adding and changing node settings.
- Save From Edit Mode
- Enter into Edit Mode to make changes. Only changes to the Z axis will be saved. The mesh will be reverted and changes not saved if an vertices or edges are added during this mode.
- Save From Sculpt Mode
- Enter into Sculpt Mode to make changes. Only changes to the Z axis will be saved. Do not turn on Dynamic Topology or else the mesh will be reverted and any changes unsaved.
- Clear Vertex Edits
- Clicking this button will clear the edits saved to this node
Saving Edits:
Changes are saved when clicking either of the Save from Mode buttons which enters into its respective mode for changes to happen. Once Object Mode has been re-entered the new coordinates are compared with the original coordinates and the difference is added to what was saved previously.
- Each Vertex Edits node can save a new and completely different edit.
- The mesh will be updated to the point the Vertex Edits node exists in the tree. So what is visible in Object Mode may change once Save from Mode has been clicked
- Making changes to the Grid node may cause errors. To fix these errors go back to your original density and size OR clear the edits and do them again.
