The perspective of the player looking at the cubemap is not right. It is not in the middle of the cubemap, that makes the cubemap looks blocky

Steps to Reproduce:
1. Insert the cubemaps to cubemap folder in your texture pack (textures/environment/cubemaps)
2. Install the texture packs
3. Activate the texture packs in Minecraft
4. You can see the every corner of the cubemaps are blocky

Observed Results:
It happens on every Minecraft Bedrock Versions, you can actually see the cubemap looks blocky at the corners. And This Is Not About Third Parties or Marketplace, this is a bug from the Minecraft Bedrock Graphics

Expected Results:
The player perspective should be in the middle of the cubemap box, so the cubemap wouldn't look blocky
