Error when using PBRMaterial

[onetrickwolf]

var material = new BABYLON.PBRMaterial("ball player", scene);
material.diffuseTexture = new BABYLON.Texture("assets/02_Ball Player/ball_player_D.png", scene);
material.bumpTexture = new BABYLON.Texture("assets/02_Ball Player/ball_player_N.png", scene);
material.specularTexture = new BABYLON.Texture("assets/02_Ball Player/ball_player_S.png", scene);

//Attach the material to the sphere
mesh.material = material;

The above works fine when swapping out PBRMaterial with StandardMaterial.  When I do PBRMaterial though I'm getting: Uncaught TypeError: Cannot read property 'PrepareDefinesForLights' of undefined

Any ideas?  Thank you sorry still trying to figure this out.

what happens when you try this

var pbr = new BABYLON.PBRMaterial("pbr", scene);
pbr.cameraExposure = 0.66;
pbr.cameraContrast = 1.66;

and assign that to the mesh
or

    //Creation of a material
    var materialSphere = new BABYLON.PBRMaterial("Material_" + j, scene);
    materialSphere.albedoColor = new BABYLON.Color3(0.2, 0.9, 1.0);
    materialSphere.reflectivityColor = new BABYLON.Color3(reflectivity, reflectivity, reflectivity);
    materialSphere.microSurface = microSurface;

materialSphere.reflectivityTexture = texture;
materialSphere.useMicroSurfaceFromReflectivityMap = true

they are direct copy and pastes from http://doc.babylonjs.com/overviews/Physically_Based_Rendering
 

also what kind of light do you have in the scene?  Im pretty sure a PBR would be dependent on the lighting seeing how its trying to simulate a realistic model...  perhaps try changing your lights?  Im not sure I have not yet got to PBR implementation on any of my projects yet so this is kinda just a shot out in the dark.  But from what I see its properties are not the same as the standard material.

You need to use the latest babylon.js 2.4 I guess

Updated to preview release worked thanks didn't know this was a preview feature!  However, the only texture that works is the bumpTexture (it looks amazing though!).  The diffuse and specular don't seem to be working.  Any idea why?

Thanks for always be so helpful Deltakosh will try to repay the forum in the future by answering questions once I know more!

it should work  can you try to reproduce your issue on the PG?

[onetrickwolf]

Hmm not sure how to load external files on the playground but here is the full code that's giving me issues: http://www.babylonjs-playground.com/#UUZUS#3

You have to reference files form an open CORS server (or just use textures already in the PG like here: http://www.babylonjs-playground.com/?28)

I replaced diffuseTexture with albedoTexture and that seemed to work. Is that just a difference between PBR and standard?  Having trouble figuring out what the equivalent to specular would be.

[GameMonetize]

specular is defined by reflectivityTexture

We will update the doc!
