Debris

Overview

The Debris Simulation adds larger amounts of individual particles to your terrain using a physics simulation. The particles are spawned based on a density value per level step, unlike the other simulation layers. Gravity and interactions with each other affect them, creating a realistic distribution across the terrain.

Spawning debris on all levels allows for a greater variety of element sizes. This means that debris spawned on lower levels will be much larger than debris spawned on higher levels, creating a more natural ratio between large boulders and smaller pebbles.

Parameters

• Density The spawn density of debris on the terrain.

Simulation

• Delta The time step delta of the simulation. Can be used to speed it up or slow it down (in relation to the iterations).

• Friction The amount of friction that will be applied to the debris.

• Acceleration How fast the elements accelerate on the terrain.

• Collision Bounce Controls the strength of the reaction when colliding with another particle.

Shape

• Insert Level The level in which the simulated debris will be added to the terrain. Densities on levels above the insert level will be ignored!

• Shape Offers you a variety of different shapes, from imported textures and meshes to procedural 2d splats.

• Texture/Model Reference to your custom linked texture/model.

• Shape Detail Amp (only procedural shapes) Noise scaling for the procedural shapes.

• Height Height multiplier for all rendered elements.

• Size Range of randomized size of all rendered elements.

• Rotation Range of randomized rotation of all rendered elements.

Tint

• Gradient Allows you to apply additional coloring to your distributed debris. To see this on your terrain you have to have a material with "Use Shape Layer Color" enabled. For more info on the gradient itself please refer to the info in the Gradient Material.
