PMREMGenerator resolution for glossy reflections

Questions
1

Hi all,

I’ve currently a project with THREE JS R135. I know that i’ve to upgrade it. But my main problem is that i need to use very glossy reflexions (roughness < 0.04). I tried to use a big size HDR (equirectangular) file but, with PMREMGenerator, nothing change. The reflexions are not quality.

I use this code to load :

            var pmremGenerator;
            pmremGenerator = new THREE.PMREMGenerator(renderer);
            pmremGenerator.compileEquirectangularShader();
            texture = pmremGenerator.fromEquirectangular(url).texture;
            pmremGenerator.dispose();

So, my question is : is there a way to have nice reflexions for low roughness MeshPhysicalMaterial or not ? If yes, what it is ? And, is there a chance to have better result after upgrade of my three JS release ?

Thanks a lot for your help !

Have a nice day.
