Texture missing after implementing custom hdr

[RathodDeven]

Wanted to implement custom hdr reflection, thus replace envmap with my hdr envmap instead of the one generated by skybox generateEnvironmentMap function. Here, rgbeEnvMap is hdr texture from RGBELoader. File : `environment-system.js`

const rgbe = new RGBELoader().load(
  "https://metasp-assets-c1a5b420.s3.us-west-2.amazonaws.com/spoke/assets/models/amphitheatre_zanzibar_fort_1k.hdr",
  function(texture) {
    texture.mapping = THREE.EquirectangularReflectionMapping;
    console.log("sky.js rgbeloader texture", texture);
    rgbeEnvMap = texture;
  }
);

I got hdr reflection as shown in below image, but all the textures from below turned pink as shown in the first image.

I am not sure why only below textures turned pink. I have just switched envmap generated from skybox to my own envmap.
