babylonjs and xnormal

[unicomp21]

Has anyone used xnormal mikkt space normal maps and ambient occlusion maps in babylonjs?  I'm getting artifacts in babylonjs which aren't visible in the xnormal viewer.  It's almost like the normals aren't getting interpolated.

Hey

How do you use them? through a custom shader?

[unicomp21]

No, no customer shader, just using the StandardMaterial.  Added a couple screen shots.  Polygons are visible in babylon.

you need Make a normal Map

That screenshot is with both the ambient occlusion and normal maps.

[NasimiAsl]

so what is the problem now

[unicomp21]

The quads are highly visible in babylon, but not in xnormal viewer.

Where do you set the ambiant occlusion (As we do not support it in the standard shader :))

[unicomp21]

Here's my code, it all seems to work, but chunky looking in the bump texture.  Again, looks good in xnormal viewer, but not in babylonjs.

var material = new BABYLON.StandardMaterial("material1", scene);
var ext = ".png";
material.bumpTexture = new BABYLON.Texture("geometry/meta_balls_normals" + ext, scene);
material.ambientTexture = new BABYLON.Texture("geometry/meta_balls_occlusion" + ext, scene);
//material.diffuseTexture = new BABYLON.Texture("geometry/metaballs_vcols" + ext, scene);
mesh_root.material = material;

btw, commenting out the bumpTexture, I can see the ambient texture.

the bump texture as to be a normal map like this: https://github.com/BabylonJS/Samples/blob/master/Assets/normalMap.jpg

The normal map indicated above appears to be mikkt space, ie same as Blender, which is the same format I'm exporting from xnormal.

attached and my bump and ambient occlusion maps

and here is the low poly model ...

Sure but this does not help a lot  Can you create a repo on the Playground? (But basically, this should work if UV are exported correctly)

[unicomp21]

Ok, will do.
