Hi!

When I work with ATF textures and alphaBlending in a plane… always away3d put a white glow around the image with alpha. If I don’t use atf and I use Bitmap, the white glow don’t appear….

Someone know solve this?

Thanks!! I hope your commets.

I’m also interested concerning this issue…

Me too,

any clues?

One of you post an example + assets.
So it can be tested logged as bug etc.

Yes.

I’ve made an example of the bug. You can download it from:

http://www.lucky-pig.net/away3d_atf_alphablending_bug.zip

In the bin folder you have an AIR file for instal and test it.

In the src folder you have a Main.as with the code, how you can see, the atf is from the png, but in the plane of the left (ATF) the texture have a white-yellow glow but in the plane of the right (PNG) works fine.

This happen always that you have an ATF texture in a material with alphablending=true.

This is a very important problem because we can’t use the benefits of ATF if we need alphablending….

Do you need any more for test it?

Regards! I hope your comments.

Put this diffuse.atf in the folder:

bin/assets/

I can’t put it in the away3d_atf_alphablending_bug.zip

Sorry!

Try
materialATF.alphaPremultiplied = false;

It works fine for me!

A lot of thanks! Really a lot of thanks!

Can you say me why happen this?

Regards!

This unity thread goes into it a bit.

Even with premultiplied off you will still get some halo at oblique angles.
See left swf image.

Just had a quick play and you get a bit better results with PS and saving as png8 with a mat of similar color.
Then converting to atf.
See right swf image

Thanks John!
