Desktop and android different rendering Software: Away3D 4.x

marbu, Newbie Posted: 24 December 2013 04:00 PM Total Posts: 3 Hi to all, I try to develop a very simple app in air using A3D. I’ve a scene with 3 balls with TextureMaterial and when I run the app on desktop it’s all ok: Screenshot desktop When I try the app on android it has some problems: Android Screenshot This is my code: `var tx:BitmapTexture = event.asset as BitmapTexture; var txMaterial:TextureMaterial = new TextureMaterial(tx, true, false, false); txMaterial.repeat = false; txMaterial.bothSides = true; txMaterial.ambientColor = 0xcccccc; txMaterial.lightPicker = Game.instance._lightPicker;` I do some search and I find that alphaBlending can solve the problem but if I set: `txMaterial.alphaBlending = true; txMaterial.alphaThreshold = 0.5;` The result is the same on desktop and android but it is wrong: Screenshot with alphaBlending It seems that the z-order with alphaBlending is right in android also but there are some other problems…. can someone help me? thanks.

Alphathreshold defines the point at which the material becomes invisible. Alphablending uses the alpha value of each pixel. That may not be the problem though. You will find a lot of threads about Alphabelnding and it’s possible effect on z-sorting. Use alphathreshold alone, if you can use the sharp edges it produces. Good Luck!
