Modifiers

Blur

Geometry Blur Modifier UI

Opacity

Impact amount on the modifier's final output

Blur Opacity Example

Iterations

Number of repetitions of mixing value with neighbors.

Blur Iterations Example

Weight

Effectively the blur factor

Height Only

Only blur the Z axis

Blur Iterations with Height Only Disabled

Curve

If the height anchor for the terrain is set to anything other than None the terrain will most likely not meet up with the curve.

Curve Object

The curve object to use with this modifier

Add Curve

Create a new curve, set it as the active on on the modifier, enter edit mode for the curve, set Blender's Draw Curve tool to be the active tool in the viewport for quick adding of curves.

Note

The height of the curve while drawing is set by the 3D Cursor by default.

Info

Pressing Enter will exit the mode while pressing Esc or Right-Click will exit this mode and remove the curve(s).

Valley Width

Vary the width of the valley floor.

Cliff Slope

Vary the steepness of the valley's walls.

Orginal Details

Add back in the details from before the modifier was applied.

Valley Shape

Similar to falloff easing choose the shape of the valley's walls

See Easing Functions for more information.

Smoothing

Curve Resolution

Artificially vary the resolution to remove lines.

Smooth Extra

Smooth out the valley even more if lines are still there after maxing out Curve Resolution.

Randomize

This is a different type of randomize than the others since it's a long path.

Smooth

Blur noise result to remove sharp edges as a result of the noise.

Amount

The intensity of the noise.

Scale

How close together the randomness of the noise is

Detail

Vary the detail level

Distortion

Amount of distortion.

Seed

Randomize the noise.

Dilate / Erode

Not compatible with Adaptive Subdivision grid type

Effect Type: Dilate

Effect Type: Erode

Iterations

The amount of times to repeat the process. Higher iterations will result in a stronger effect but will also increase the processing time.

Dilate Erode
0 - 60 iterations 0 - 60 iterations
Noise Amount

Add noise to the dilation/erosion effect to create a more natural and less uniform result.

Flatten Area

Choose an area to create a flat(ter) surface to put landmarks, houses, cities, or just to modifier the terrain to your use.

Here the Flatten Area modifier is used to extend the top surface out for the statue. Please someone create a better example image.

Location Type
  • Location: Set the location manually where the terrain should be flat
  • Object: Let an object's location decide where the terrian should be flattened

Note

Regardless of Location Type the Z axis will decide the height of the flattened area either what is set in the Location setting or the Z axis of the object

Radius

How far away from the location to flatten the terrain.

Invert

Flatten everything outside the radius instead.

Height Offset

Offset the flattened area's height from the Location Type.

Info

Only visible if Use Object Height is disabled

Use Object Height

Use an object to set the height value.

Offset Object

The object to use as the height of the flattened area.

Info

Only visible if Use Object Height is enabled

Falloff

Distance outside of the radius to fade out the flattening effect.

Easing

Choose a different method to falloff. See the Easing Functions for more information.

Randomize

Add noise to the Radius to have a more organic border to the flattened area.

See the Randomize Settings for more information.

Terracing

Terracing modifier example.
Send in a better example image of terracing to be featured here!

Cliff Heights

Distance between each terraced cliff.

Surface Width

Increase/decrease the flat surface area.

Inflate/Deflate

Geometry Inflate/Defalte Modifier UI

Opacity

The amount this modifier is applied

Amount

Home much to inflate/deflate the terrain

Inflate Amount Example

Deflate

Invert the effect. Helpful to sharpen the details of the terrain.

Deflate Amount Example

Blur Iterations

The amount of times to blur the inflate/deflate effect

Blur Iterations Example

Blur Factor

Reduce the blur amount

Path

Curve

The curve object to use for the path modifier.

Add Curve

Click to draw a curve in the viewport to use for the path modifier. Pressing Enter will exit the mode while pressing Esc or Right-Click will exit this mode and remove the curve(s).

Width

How wide the path should be.

See Randomize Settings for more information on the randomize width settings.

Path Type

How the path should be applied to the terrain.

  • Deform: Deform the terrain up or down to match the curve.
  • Follow: The terrain will follow the path but not be deformed to match it, like a dirt path.

Path Type: Deform

Raise or lower the terrain to match the curve. This is good for creating things like roads or land bridges that are sunken into the terrain or traverse valleys.

Intersection Height Method

When curves intersect with each other or themselves, this setting will determine how the height of the intersection is calculated.

Minimum

Choose the lowest height at the intersection.

Average

Choose the average height at the intersection.

Maximum

Choose the maximum height at the intersection.

Apply Paths Mode

Lower Only

Only lower the terrain to match the curve. This is good for creating things like roads or land bridges that are sunken into the terrain. Any sort of "bridge" for the path will need to be created otherwise.

Conform

Both lower and raise the terrain to match the curve. This is good for creating things like roads or land bridges that are traversing valleys or hills.

Raise Only

Only raise the terrain to match the curve. This is good for creating things like roads or land bridges that are traversing valleys or hills. Any sort of "bridge" for the path will need to be created otherwise.

Falloff

Vary the distance outside of the path's width to fade out the effect.

Split Falloff

Split the falloff into two separate values to have more control over the falloff on places where the terrain is higher than the curve and lower than the curve.

Falloff - Cliff

The distance outside of the path's width to fade out the effect when the terrain is higher than the curve. This is good for creating sharper cliffs on the edges of paths.

Falloff - Downhill

The distance outside of the path's width to fade out the effect when the terrain is lower than the curve. This is good for creating smoother falloffs on the edges of paths.

Handle Intersections

Enable or Disable special handling for curve intersections. When enabled, the terrain will be modified to meet up with itself at the intersection. When disabled, the terrain will raise or lower according to the closest point on the curve.

Path Type: Folow

A path that smooths the terrain without raising or lowering it. This is good for creating things like dirt paths or trails that follow the terrain.

Ignore Heights

When enabled, the terrain will be smoothed to follow the curve regardless of how far above or below the curve the terrain is. Useful if you do not care if the path does not bridge over valleys or hills and just want a path that follows the terrain.

More Defined Edges

Ignore Heights is enabled in both images.

When enabled, the edges of the path will be more defined and less smooth. This is good for creating things like dirt paths or trails that follow the terrain but still have a bit of definition to them.

Smooth Amount

From 0.0 to 1.0

The amount to smooth the terrain around the curve.
