Accessors

oitMode

Get Signature

get oitMode(): "sorted" | "weighted" | "depth-peel"

Defined in: src/materials/Material.ts:69

Order-independent transparency mode opt-in.

• 'sorted' (default): back-to-front sorted alpha-blend. Cheap, correct between meshes, but in-mesh triangle order is geometry- based not depth-based so self-overlapping meshes (spheres, torus) show banding.
• 'weighted': McGuire-Bavoil 2013 Weighted-Blended OIT. Single- pass, order-independent, no in-mesh banding. Approximate — accum.rgb/accum.a degenerates to a depth-weighted average so α=1 looks averaged-milky at small scene scales (the front-vs- back depth-weight ratio saturates the paper's z/200 norm). Use for unbounded transparent layer counts: particles, smoke, foliage, hair cards.
• 'depth-peel': Dual depth peeling. Multi-pass (passCount × 2 layers), order-correct over operator. α=1 is cleanly opaque — front fragment dominates because subsequent layers get multiplied by (1 - frontColor.a) = 0. Hard layer count limit (default 10). Use for hero glass, scientific visualization, layered architectural geometry.

All three only take effect when engine.setting.render.useOIT is true (otherwise everything falls through the sorted path).

Setter notifies attached renderers so the corresponding derived pass(es) get lazily generated when flipping mode at runtime. Without this, callers had to follow up with an alphaMode setter call to provoke refreshRenderClassification → castNeedPass.

Documented at Material-level (not LitMaterial) so any future material subclass (particle, decal) can opt in.
