我正在开发顶点蒙皮着色器，由于某种原因我的程序无法找到统一的位置。
顶点着色器代码：
#version 330
const int MAX_JOINTS = 30;
const int MAX_WEIGHTS = 3;
in vec3 position;
in vec2 textureCoords;
in vec3 normal;
in ivec3 boneIndices;
in vec3 weights;
out vec4 fragPos;
out vec3 n;
out vec2 texCoords;
out vec4 mcolor;
uniform mat4 modelMatrix;
uniform mat4 projectionMatrix;
uniform mat4 viewMatrix;
uniform mat4 normalMatrix;
uniform mat4[MAX_JOINTS] boneTransforms;
void main() {
vec4 totalLocalPos = vec4(0.0);
vec4 totalNormal = vec4(0.0);
for(int i = 0; i < 3; i++){
mat4 boneTransform = boneTransforms[boneIndices[i]];
vec4 …
