Hi :smiley: I’m facing some issues here with Babylon version 4 (tried 4.0.3 and 4.1.0-alpha26). I’m using the PBRMetallicRoughnessMaterial material that is working well with the version 3.3.0, as you can see in this image: [downloa01d] But with version 4, the environment texture is not being app…

Am I wrong if I suppose that you’re envTexture isn’t HDR? (App.url + '/objects/skybox/skybox') + your hemilight could also help to burn white values (by the way, you don’t really have pure white materials values IRL). https://www.babylonjs-playground.com/#I4SMJ4#3

Pinging @sebavan (please be patient as seb will be back on monday)

Hi @Deltakosh and @Vinc3r , thanks for responding… @Vinc3r … I removed the HemiLight and yes, it worked well :smiley: but I don’t understand why it is working with the HemiLight on v3… is there any difference? I was using the HemiLight to control if the scene is more or less bright; About the textur…

Not here to comment on the change happening, but with PBR I have developed the method of always wanting the environment texture to be as bright as possible to avoid lights, which can only add to fragment processing and probably JS too. If you can do that, then with a simple, little loop, you can ad…

Thanks, @JCPalmer , that is a good approach. I’ll try it here. I have one question: What you do if you need shadows in someplace?

Good question. First, I assume you are taking about dynamic shadows, not the baked ones. If I wanted one, of course I would add a light. Shadows can seem really faint in a PBR scene due to the environment texture. To avoid that, I would set the intensity on the shadow receiving mesh low enough, …

Wow, interesting… I’ll try it here. I noticed that the shadows are very faint with PBR, but I didn’t know why. Thank you :smiley:

Hey guys, although without a HemiLight it worked well, I needed to add a directional light to get a similar and better effect. But, after a lot of tries, I can’t make the same beautiful effect as it is on version 3.3. Any idea about it? The original with v3.3 and Hemilight: [image] On v4, without…

Let s add @PatrickRyan who might help on the setup.

@TiagoSilvaPereira I’m happy to help you with a setup but would prefer to be setting up a scene with your assets. Is there any way you can share a playground with us? If not, would you be able to share the skybox and obj with us so we can recreate and debug mirroring your scene rather than making as…

Thank you @PatrickRyan , for sure, here is the playground: Babylon.js Playground If you try with v3.3, this is exactly the scene I’m trying to do. But if you change to v4, you will notice that the scene is no more like in v3.3. Thank you very much for helping :smiley: EDIT: Fixed the playground li…
