Specular lighting is gone after upgrading from beta5 to rc1

[HoloLite]

I noticed that the specular light effects in my app has completely disappeared in rc1. It was working in beta5. 

Has anything changed? Is this a bug ?

Thanks

Nothing should have changed here that I know, I can also still see the specular effects in all the test PG I looked at. Do you have more precision on how you are using it (this might help troubleshooting) ?

I am using 2 lights: hemi and directional. The code fragment is the following.

The this.light is directional light. The this.hemilight is hemispheric light.

     
                this.light.intensity = 2.0;
                this.light.direction = new BABYLON.Vector3(0.1, 0.9, 0.1);
                this.light.diffuse = new BABYLON.Color3(1, 1, 1);
                this.light.specular = new BABYLON.Color3(0.5, 0.5, 0.5);

                this.hemiLight.intensity = 1.0;
                this.hemiLight.direction = new BABYLON.Vector3(0.1, 0.9, 0.1);
                this.setSkyboxSettings("material.inclination", this.skyboxMaterial.inclination, 0); 
                

This would give the specular lighting effect in the app, until rc1.

Hello,

I can still see it on both standard and pbr:

Thanks for looking into this.

My meshes are using materials with diffuse textures. I wonder if some default values have changed recently in beta1.

Still seems to work as well. It is really hard to troubleshoot without PG:

HEHEHE no wonder you cannot reproduce it. You did it with rc2 and apparently it was fixed in rc2. I just updated my app to rc2 and the issue was gone.
The issue was indeed present in rc1 though.

Thanks for looking into this anyway!
