Hi,
The sky was obtained through the method below.
Spatial sky = SkyFactory.createSky(this.app.getAssetManager(), “Textures/Sky/Bright/blue_sky_512x512_2.png”, SkyFactory.EnvMapType.SphereMap);
I noticed this problem for two android devices:
- Samsung Galaxy Tab S3;
- Motorola Moto Maxx.
The following figures show the normal situation and the error situation.

In fact, after some tests, I realized that the sky was not being rendered.
After a few more tests, I identified where the problem occurs.
In the file Sky.j3md has the following definition:
RenderState {
DepthWrite Off
DepthFunc Equal
}
The problem is in DepthFunc = Equal. For rendering to have to be DepthFunc = LessOrEqual.
To work around the problem I did the following after calling the SkyFactory.createSky function:
Geometry g = (Geometry) sky;
//Bug fix para Samsung Galaxy Tab S3 e Motorola Moto Maxx
g.getMaterial().getAdditionalRenderState().setDepthFunc(RenderState.TestFunction.LessOrEqual);

Love you dude!!! Spent a lot of time to get it working, with this parameter set, everything goes beautiful!!!
In addition want to provide example of creating sky geometry, here is my example:
Kotlin code, taken from default SkyFactory
private fun createSky(sphereRadius : Float, normalScale : Vector3f, texture : Texture) : Geometry {
val sphereMesh = Sphere(10, 10, sphereRadius, false, true)
sky = Geometry(“Sky”, sphereMesh)
sky.queueBucket = RenderQueue.Bucket.Sky
sky.cullHint = Spatial.CullHint.Never
sky.modelBound = BoundingSphere(Float.POSITIVE_INFINITY, Vector3f.ZERO)
val skyMat = Material(assetManager, “Common/MatDefs/Misc/Sky.j3md”)
skyMat.setVector3(“NormalScale”, normalScale)
skyMat.setBoolean(“EquirectMap”, true)
texture.magFilter = Texture.MagFilter.Bilinear
texture.minFilter = Texture.MinFilter.BilinearNoMipMaps
texture.anisotropicFilter = 0
texture.setWrap(Texture.WrapMode.EdgeClamp)
skyMat.setTexture(“Texture”, texture)
skyMat.additionalRenderState.depthFunc = RenderState.TestFunction.LessOrEqual
sky.material = skyMat
return sky
}

Hello Rukurbanov,
I’m glad I could help.
