Placement Target Modes Explained

The Placement Tool features several target modes to accommodate various asset-selection scenarios. Below are the available modes, along with descriptions and key settings.

Random Weighted Selection

• Purpose:

  • Chooses a random asset for each placement, using per‑asset weights to bias the probability.

• Ideal For:

  • Varying repeated props with controlled frequency (e.g., foliage or debris).

  • Procedural setups where some assets should appear more often than others.

• Key Settings:

  • Asset Weight: Set per entry to influence selection probability.

  • Random Seed: Ensures deterministic results across sessions if desired.

  • Reroll Hotkey: Immediately picks another random asset.

• Optional Settings:

  • Reroll can be triggered manually at any time to preview alternative assets.

Keep Index Selection

• Purpose:

  • Locks placement to a specific asset index until changed manually.

• Ideal For:

  • Repeatedly placing the same asset without random variation.

  • Manually stepping through a list to audition assets.

• Key Settings:

  • Current Linear Index: Specifies which asset to use.

  • Next/Previous Hotkeys: Cycle indices directly from the viewport.

• Optional Settings:

  • Wrap Cycle: Allows cycling to loop back to the start or end when navigating beyond bounds.

Cycle Selection

• Purpose:

  • Automatically advances to the next asset in the list with each placement.

• Ideal For:

  • Creating patterned layouts where assets should appear in a predictable order.

  • Rapidly iterating through a sequence of props or decals.

• Key Settings:

  • Starting Index: Defines the initial point in the sequence.

  • Next/Previous Hotkeys: Manually move forward or backward through the cycle.

• Optional Settings:

  • Wrap Cycle: Enables looping at the ends.

  • Reroll Hotkey: Temporarily overrides the cycle with a random pick if desired.

Reroll On-Demand Selection

• Purpose:

  • Keeps the current asset until a manual reroll chooses a new one.

• Ideal For:

  • Situations where you want a stable default asset but occasionally swap it out.

  • Controlled randomization at specific times.

• Key Settings:

  • Reroll Hotkey: Selects a new asset either weighted or uniformly at random.

  • Random Seed: Reproduces the same sequence of rerolls.

  • Unique Reroll: Option to guarantee the new pick differs from the current one.

• Optional Settings:

  • Disable unique reroll if repeats are acceptable.

Each target mode is easily selectable in the tool’s settings panel. Adjust the associated variables to match your project’s requirements.
