SpriteBlendMode

Enum SpriteBlendMode 

Source 
pub enum SpriteBlendMode {
    Alpha,
    Additive,
}
Expand description

Blend modes the GPU pipeline understands. MD2 specced more (decal, overlay, multiply, …) but corpus sprites overwhelmingly use Alpha or Additive — the renderer’s two pipelines cover both. Unknown / unsupported blendmode values from the per-frame eval snap to Alpha.

Variants§

§

Alpha

Standard alpha blend (src.a, 1 - src.a).

§

Additive

Additive (one, one) — useful for glow / particle effects.
