solved Problem with PBRSpecularGlossinessMaterial when migrating from 3.2 to 3.3

Hey!

I'm moving from babylon 3.2 to 3.3 and encountered very strange behaviour regarding materials with environment map generated from reflection probes. All materials became very glossy and parameters tuning doesn't help to solve this.

Hello and welcome to the forum,

First of, your scene looks really nice and are you relying on Babylon reflection probes or any kind of hdr files ?

A repro in the playground would be amazing.

Yes, we relying on reflection probes. Ok. I'll make an example in playground

Ok underdstood, thanks.

As we are trying to work towards a real time solution for prefiltering cube texture from probes, we fixed some default setup of prefiltreing but it unfortunately impacted the probes.

As a workaround you can set manually the lod generation offsets and scale in your application. I will update the reflection probe to their default previous setup:

probe.cubeTexture.lodGenerationOffset = 0;

probe.cubeTexture.lodGenerationScale = 0.8;

I am really hoping for a first implementation of real time filtering in 4.0.

It works! thanks a lot
