Opacity¶
Cut-out by a mask: fences, nets, grates, torn cloth, leaves. Asset (Mask Map channel), Foliage / Decals (Base Color alpha by default).
Blend Mode Masked
The masters are Opaque. In the instance: Material Property Overrides → tick Blend Mode → Masked. Masked costs more: only where something is cut out.
| Parameter / switch | What it does | Typical value |
|---|---|---|
| Use Opacity? + Opacity Channel | Turns the cut-out on (Asset) / which Mask Map channel | |
| Opacity Offset | + = more solid, − = more cut | 0 |
| Opacity Contrast / Opacity Invert? | Edge crispness / swap visible and cut | 1 / off |
| Use Soft Opacity? | Smooth wires and edges without stairs or shimmer at any distance. Needs TSR / TAA | on for fences, nets |
| Soft Opacity Edge | Where the cut is; lower = thicker wires | 0.333 |
| Soft Opacity Width | Edge width in pixels | 1, softer 2–3 |
| Use Camera Fade? | Dithers the surface out near the camera (camera inside a bush) | Foliage |
| Camera Fade Start / Length | Fade distance in cm | 50 / 100 |
Tips¶
- Chain-link fence: Masked + Use Soft Opacity?; thin wires disappear far away → lower Soft Opacity Edge.
- Shadows always get a clean cut.
- Cost: Soft Opacity +10 instructions, Camera Fade +14.
