Why is it flickering on the sides? It’s simple CylinderGeometry with TextureMaterial:
var coinMaterial:TextureMaterial = new TextureMaterial(Cast.bitmapTexture(DIFFUSE_TEXTURE));
coinMaterial.specularMap = Cast.bitmapTexture(SPECULAR_TEXTURE);
coinMaterial.normalMap = Cast.bitmapTexture(NORMAL_TEXTURE);
coinMaterial.lightPicker = lightPicker;
coinMaterial.specular = 3;
coinMaterial.ambient = 1;
coinMaterial.smooth = true;
coinMaterial.repeat = false;
coinMaterial.mipmap = false;
coinMaterial.animateUVs = true;
var coin:Mesh = new Mesh(new CylinderGeometry(300, 300, 20, 50, 1, true, true, true, true), coinMaterial);
coin.rotationX = 90
coin.subMeshes[0].scaleU = 0.5
coin.subMeshes[0].offsetU = -0.005
scene.addChild(coin);
