顶点着色器属性位置中的损坏数据

由于顶点着色器属性位置中的数据损坏，我的模型看起来很拉伸

这是顶点着色器代码：

#version 330 core

layout (location = 0) in vec3 vertPos;
layout (location = 1) in vec3 vertNormal;
layout (location = 2) in vec2 texCoord;
layout (location = 3) in vec4 boneWeigths;
layout (location = 4) in ivec4 boneIDs;

out vec3 vNormal;
out vec3 fragPos;
out vec2 fragTexCoord;

const int MAX_BONES = 100;

uniform mat4 MVP;
uniform mat4 M;
uniform mat4 boneTransforms[MAX_BONES];

void main()
{
    mat4 boneTx = boneTransforms[boneIDs[0]] * boneWeigths[0]
                + boneTransforms[boneIDs[1]] * boneWeigths[1]
                + boneTransforms[boneIDs[2]] * boneWeigths[2]
                + boneTransforms[boneIDs[3]] * boneWeigths[3];
    vec4 pos = boneTx * vec4(vertPos, 1.0f);
    gl_Position = MVP * pos;
    vec4 normal = boneTx * vec4(vertNormal, 0.0f);
    vNormal = normalize(vec3(M * normal));
    fragPos = vec3(M * pos);
    fragTexCoord = vec2(texCoord.x, texCoord.y);
}

问题似乎是boneIDs中的数据已损坏（boneIDs数据在CPU上正常，但在着色器中获取了损坏的数据）。我尝试在着色器中硬编码boneIDs数据，并且效果很好。

这是VAO的代码：

    // create buffers/arrays
    glGenVertexArrays(1, &VAO);
    glGenBuffers(1, &VBO);
    glGenBuffers(1, &EBO);

    glBindVertexArray(VAO);
    // load data into vertex buffers
    glBindBuffer(GL_ARRAY_BUFFER, VBO);
    unsigned int sz = sizeof(BoneVertex);
    glBufferData(GL_ARRAY_BUFFER, vertices.size() * sizeof(BoneVertex), &vertices[0], GL_STATIC_DRAW);

    glBindBuffer(GL_ELEMENT_ARRAY_BUFFER, EBO);
    glBufferData(GL_ELEMENT_ARRAY_BUFFER, indices.size() * sizeof(unsigned int), &indices[0], GL_STATIC_DRAW);

    // set the vertex attribute pointers
    // vertex Positions
    glEnableVertexAttribArray(0);
    glVertexAttribPointer(0, 3, GL_FLOAT, GL_FALSE, sizeof(BoneVertex), (void*)0);
    // vertex normals
    glEnableVertexAttribArray(1);
    glVertexAttribPointer(1, 3, GL_FLOAT, GL_FALSE, sizeof(BoneVertex), (void*)(3 * sizeof(float)));
    // vertex texture coords
    glEnableVertexAttribArray(2);
    glVertexAttribPointer(2, 2, GL_FLOAT, GL_FALSE, sizeof(BoneVertex), (void*)(6 * sizeof(float)));
    // bone weights
    glEnableVertexAttribArray(3);
    glVertexAttribPointer(3, 4, GL_FLOAT, GL_FALSE, sizeof(BoneVertex), (void*)(8 * sizeof(float)));
    // bone ids
    glEnableVertexAttribArray(4);
    glVertexAttribPointer(4, 4, GL_INT, GL_FALSE, sizeof(BoneVertex), (void*)(12 * sizeof(float)));

    glBindVertexArray(0);

BoneVertex结构：

struct BoneVertex
{
    glm::vec3 position;
    glm::vec3 normal;
    glm::vec2 textureCoords;
    glm::vec4 boneWeights;
    glm::ivec4 boneIDs;
}

这很奇怪，因为前三个属性数据看起来不错。问题在于boneIDs和boneWeights这是否与填充有关，数据如何在结构中排列？还是我想念其他东西？

谢谢
