Jurassic World Evolution 3 Guide | How to Adjust Slopes and Create Waterfalls

Here's an easy guide on the tools and waterfall.

When loading into a new map and opening the terrain tools, the slope setting is automatically set two bars below the maximum. While this setting works, it can be inconsistent when forming waterfalls.

Increasing the slope

Increasing the slope to its maximum creates smoother, more continuous waterfalls along inclines. A steeper slope ensures that water flows properly without breaking up or stopping in midstream. If waterfalls aren't forming as expected, increasing the slope often fixes the problem.

However, there's a limit to how tall a waterfall can be. Beyond a certain height, waterfalls stop generating properly. The water may disappear or refuse to connect between the top and bottom of the cliff. Shorter waterfalls, on the other hand, work much more reliably.

River Rapids or Cascades

By slightly adjusting the slope, it's possible to create natural river rapids or gentle cascades. Reducing the slope too much, though, will stop the water effect entirely. When waterfalls aren't working, it usually means the slope is too shallow or the height exceeds the limit.

Full Terrain Tools Guide

The terrain tools include several functions to shape the land.

Raise and Lower: These options raise or lower terrain freely.

Flatten: This levels the terrain to match the height under the cursor.

Both Raise to Flatten and Lower to Flatten move the terrain in one direction — upward or downward — but they adjust it to match a flat surface.

Roughen: This adds more natural-looking lumps and unevenness to the terrain. Roughing adds reality to perfectly flat terrain, which frequently appears unnatural.

Smooth: Softens sharp edges and evens out bumps.

Smooth Top and Smooth Bottom: These concentrate the smoothing on a single cliff face. While "Smooth Top" softens the upper portion and maintains the lower edge crisp, "Smooth Bottom" smooths off the base.

Slope settings

Slope settings and ramps provide connections between various terrain levels. Dragging farther results in a longer ramp while maintaining the same steepness because the Fixed Ramp maintains the same angle regardless of length. The Dynamic Ramp automatically modifies its angle to fit between two specified positions.

The strength of the terrain tool's impact on the land can be changed. It modifies the landscape more slowly at low intensity and reacts rapidly at extreme intensity. Cliffs' steepness is determined by their slope. Lowering the slope produces gentle hills, whereas a maximum slope produces very vertical faces. The sharpness of the tool's transitions between untouched and modified terrain is influenced by falloff. Sharper peaks are produced by a lesser falloff, whereas smoother edges are produced by a higher one.

Painting and Surface Textures

The texture of the earth explains why rocks may be seen on some cliffs but not others. Rocks and plants are automatically included on slopes when the terrain is created with textures that incorporate them.

Painting with a "bush" texture, for instance, will create bushes on level ground; elevating that terrain will create rocky slopes. Repaint the area with a texture that excludes the rocks to remove them.

It's much simpler to create convincing cliffs, smooth hills, and flowing waterfalls in natural environments when you know how slope, height, and terrain tools work together.
