Giving the scene an environment texture which has a very low level (potentially even 0) will still fully illuminate PBR materials with `metallic=0`. On the opposite side, `metallic=1` will properly appear dark due to its reflectivity. Is there some way for the environment texture’s level to be applied to the PBR materials that aren’t reflective? There is `PBRMaterial.environmentIntensity`, but I was hoping for something that wouldn’t have to be assigned on a per-material basis.

Example link below. Note that commenting out lines 4-6 will make both spheres black, which is also what I’d expect if `environmentTexture`’s level is 0.

scene.environmentIntensity = 0.01; is what you are looking for as it will impact both specular and diffuse.

Is there a way to simultaneously make the skybox object use the same intensity? I’m okay even if this is a material property and not a global setting.

Setting `skybox.material.environmentIntensity = 0.01;` doesn’t seem to do anything like `PBRMaterial` does.

Using both `scene.environmentTexture.level = x;` and `scene.environmentIntensity = x;` will result in the reflections effectively using `intensity = x^2;`.

You can force the material of the skybox to be pbr as well [https://www.babylonjs-playground.com/#ZEP6EV#2](https://www.babylonjs-playground.com/#ZEP6EV#2)
