Hi,
I just loaded a cube model in the BabylonJS Sandbox, and loaded a .hdr file for light source. Then I am seeing an effect like below on the environment and the same is reflected on the model too.
In my project also I am facing the same issue, I am using PBR material with roughness value 1. Still there is some unwanted reflection like the same which is in above image. How to solve this?
I can’t see anything in the first circle you drew(?) Would you be able to setup a repro in the Playground so we can better understand?

please have a look into this. you will see some pattern like circles on the surface of the sphere.
I attached the screenshot of it also.
If you unable to see any thing in this screenshot. Just increase the brightness of your monitor and zoom it , then you will see the effect What I am trying to mention.
If your problem is the same as this one (but less pronunced):
I’m not sure a lot can be done about it, as you already use hdr=true…
You can try to change the tone mapping to ACES:
defaultPipeline.imageProcessing.toneMappingType =
BABYLON.ImageProcessingConfiguration.TONEMAPPING_ACES;
You could add a bit of grain to soften the artifact: https://playground.babylonjs.com/#5CE5CN#3
This is slightly worked. But It makes the overall scene dull.
Maybe you can raise the value of scene.environmentIntensity?
