🎬 Filters & Noise

These screenshots will be taken in LOOKDEV View and normal to more easily show them.

The images are shown on UE4 with the 2.0 version of the plugin, but it works the same under UE5 and PANORA|make 3.3.1

Reference image w/ no filters enabled.

The +/x/- buttons are explained in the next Blending Filters & Linking Masks section.

🎬 Noise

Normal View

LOOKDEV View

Element
Channel to Use	Uses the R, G or B values of the noise map to define the mask.
Contrast / Force	Contrasts the mask / Multiplies the mask by itself to increase its force
Tiling / Opacity	Tiles the mask / Changes max opacity of the mask

The Break UV Tiling affects the mask to give a more interesting result.

The options are the same as on the Materials or the Master Surfaces Shaders.

🎬 Directional

Normal View

LOOKDEV View

The directional filter acts as if a directional light was projected on the terrain and this light is what defined the mask.

Element
Contrast / Force / Opacity	Contrasts the mask / Multiplies the mask by itself to increase its force / Changes max opacity of the mask
Directional	Changes the direction the "light emitter" points towards. Goes from -1 to 1.

🎬 Slope

Normal View

LOOKDEV View

Advanced Mode

The advanced mode renders the slope using the angle of the terrain.

It's an heavier method but allows for settings min/max angles.

This can be useful for inputing rocks at the base of slopes, etc.

"Filter Using Normal" Option

This option uses a Normalmap to alter the filter.

The strength and UV scale of the normal used can be set and changed.

No normal filtering on the Slope filter

Normal filtering on the Slope filter

The map used can be changed in the Global Settings.

NOTE : The altered filter won't be used with Displacement ! These maps are sampled using the non-filtered normals so use with caution if you are using displacement !

Element
Steepness	The higher the value, the steeper the slopes will have to be to be affected by the mask. Recommended to not go below 0.51/0.52, otherwise all the terrain will be affected !
Contrast	Contrasts the slopes to get cleaner results.
Invert Slope	Inverts the Slope values.

🎬 Height-Based

Normal View

LOOKDEV View

The Height-Based has options to help with breaking the uniformity of the mask, as it only caps at a certain point. So multiple steps can be used and edited with a Noise.

The Medium Level Offset the mask, adding a second level of masking starting from the original value. The Lowest does the same thing starting fro the end of the Medium level.

This is useful for using a Mask map for both level, to blend maps together to have an impression of "organicness" for this mask.

HB with all levels and a mask.

Element
Invert Height	Invert Height, starting from the top or the bottom. The arrow on the mask thumbnail show the direction of the mask.
Height	Z coordinate of the start/end of the level of the mask
Fade amount	Subtracts smoothly from the Height the amount entered to get a smoother transition.
Mask Contrast	Contrasts the Mask (Medium & Lowest level only)
Mask UV Tiling	Tiles the Mask (Medium & Lowest level only)

The "Pick from selected" button sets the height from the Z coordinate of the selected actor.

Splatmap

Example with a default map

Example with a random Splatmap.

If you are using an external software like GAEA, World Machine, World Creator, or any other software to make your landscape, you can also import the Splatmap created alongside your landscape into PANORA|make, as a Mask.

Element
Contrast / Strength / Opacity	Contrasts the mask / Multiplies the mask by itself to increase its force / Changes max opacity of the mask
Layer to Use	Uses the R, G or B values of the splatmap map to define the mask.
Landscape Resolution	Samples the splatmap at the correct terrain resolution so that it can fit 1:1 on the terrain. Very Important ! You can click on your landscape and check the "Overall Resolution (Verts)" line on the details to see which values to enter. If your terrain is square and its scale hasn't been changed, you can click the "Guess" button to automatically get that value.
