Basically I can’t manage to display materials based on ATF with “partial” mipmap levels.
Empty mipmaps (-e) option doesn’t make much difference.
The attached screenshot should display 3 cubes, only the first one (that has full 11 levels mipmaps) are displayed.
They where generated with (attached in the zip):
png2atf -c -r -q 0 -f 0 -i rainbow.png -o Rainbow.atf
png2atf -c -n 0,0 -r -q 0 -f 0 -i rainbow.png -o Rainbow_mm0.atf
png2atf -c -n 0,4 -r -q 0 -f 0 -i rainbow.png -o Rainbow_mm04.atf
Disabling the “mipmap” parameter in TextureMaterial makes them appears, but ... so no mipmap at all?
Just a little dummy code:
// ATF Texture embedding
[Embed(source="/../rainbow.atf", mimeType="application/octet-stream")]
public static const Rainbow_ATF:Class;
[Embed(source="/../rainbow_mm0.atf", mimeType="application/octet-stream")]
public static const Rainbow_mm0_ATF:Class;
[Embed(source="/../rainbow_mm04.atf", mimeType="application/octet-stream")]
public static const Rainbow_mm04_ATF:Class;
// ... (any default away3d init code here)
private function createCubes():void {
var m:Mesh;
var g:CubeGeometry= new CubeGeometry();
m= new Mesh(g,new TextureMaterial(new ATFTexture(new Rainbow_ATF())));
m.x= -150;
scene.addChild(m);
m= new Mesh(g,new TextureMaterial(new ATFTexture(new Rainbow_mm0_ATF())));
scene.addChild(m);
m= new Mesh(g,new TextureMaterial(new ATFTexture(new Rainbow_mm04_ATF())));
m.x= 150;
scene.addChild(m);
}
// ...

* I am suspecting of the (maybe) outdated png2atf version…

Has someone any clue about this?
