Struct u32 field is always 0

[Steveplays28]

Hi, I'm trying to move this struct from the CPU to the GPU, but the material field is always 0. On the other hand, the position and radius fields get sent over correctly.
I tried moving the padding fields around, but the order doesn't matter. This same struct fully works as intended if I use position: Vec4, radius: Vec4 and material: i32 instead, which is what I had previously (I wanted to change it to Vec3 for ease of use).

Why would this occur?

#[derive(Debug, Clone, Copy, Default, Pod, Zeroable)]
#[repr(C)]
pub struct Voxel {
    pub position: Vec3,
    pub radius: Vec3,
    pub material: u32,
    _padding_0: u32,
    _padding_1: u32,
    _padding_2: u32,
}

Hello! Do you have a public repo I can look at to try to debug?

[Steveplays28]

Hi, currently my repository is private. I could invite you to it, if that's fine by you?

EDIT: I've sent you an invite, I'll also commit my changes to a new branch (simplify-gpu-structs)

Great, I'll try to take a look at it tomorrow

Poking at this now.

Edit: Ended up not having enough time tonight, will look into it later.
