Blur

Opacity

Impact amount on the modifier's final output

Iterations

Number of repetitions of mixing value with neighbors.

Weight

Effectively the blur factor

Height Only

Only blur the Z axis

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.

Pressing ENTER will exit the mode while presssing 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.

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.

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.

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.

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

Cliff Heights

Distance between each terraced cliff.

Surface Width

Increase/decrease the flat surface area.

Inflate/Deflate

Opacity

The amount this modifier is applied

Amount

Home much to inflate/deflate the terrain

Deflate

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

Blur Iterations

The amount of times to blur the inflate/deflate effect

Blur Factor

Reduce the blur amount
