Struct GbModelPush 

#[repr(C)]
pub struct GbModelPush {
    pub cur_model: [[f32; 4]; 4],
    pub prev_model: [[f32; 4]; 4],
    pub roughness: f32,
    pub _pad: [f32; 3],
}

The G-buffer pre-pass push constant (shared GLSL PushBlock): cur_model then prev_model (two column-major mat4) then roughness, plus a trailing pad to 16-byte alignment. The motion vector reads cur/prev model; the fragment reads roughness.

Fields

cur_model: [[f32; 4]; 4]

This frame’s model matrix, column-major.

prev_model: [[f32; 4]; 4]

The previous frame’s model matrix, for velocity.

roughness: f32

Perceptual roughness in [0, 1].

_pad: [f32; 3]

Padding so the field layout matches the shader-side struct.
