@lukostyra Thanks for the review.
We use mipmap only for diffuse and self illumination maps : https://github.com/openjdk/jfx/blob/master/modules/javafx.graphics/src/main/java/com/sun/prism/mtl/MTLPhongMaterial.java#L100

We pass this mipmap flag to the native code when texture is getting created. And we use this flag and generate mipmaps only for the textures where this flag is true : https://github.com/openjdk/jfx/blob/master/modules/javafx.graphics/src/main/native-prism-mtl/MetalTexture.m#L203

So for non-mipmapped 3D textures we don't generate mipmaps.
