I notice the 3d model animation couldn't play animation when I added the shader. When I remove it works.

We need some details (which shader you were using, what the shader code is, what kind of shader), etc.

I was using fragment shader. Just a very simple one at most.

uniform sampler2D map;

varying vec2 vUv;

void main() {

gl_FragColor = vec4(0.0, 1.0, 0.0, 1.0);

}
