alpha problem with the particles and other objects about away3d-particles-system HOT 7 CLOSED

Hi,
It's not a bug.For more information,please refer to
http://away3d.com/forum/viewthread/414/#1183
A way to solve it is not use transparent texture to the tree.

Thanks liaocheng,

and using an alphaTresold in the particles would work?

Particles has not the alphaTresold property.Maybe you can have a try to the tree.

I tried that but it doesn't work.

Thanks anyway!

"It’s not exactly a bug per sé, it’s just a problem inherent to the way blending needs to happen.
For reference:
http://www.opengl.org/wiki/Transparency_Sorting
There’s not really a way to sort per-polygon without entirely loosing the advantage of using GPU in the first place. Try to either stick to using the “alpha test” mentioned in the article (accomplished in Away3D 4 using the alphaThreshold property), or stick to (near-)convex shapes.
If you look at real games, alpha blending is pretty rare - with the exception of planar objects (water, smoke particle and other effect billboards). --"

Okey, I didn't know was alphaThreshold. I know now, and it's work perfectly. (I didn't disable alphaBlending, it is why i doesn't work before)

Thanks liaocheng, you always solve my problems XD
