Transparentized Billboards
 

Is there a way to make the background of a billboard transparent, but leave the actual picture?

[SIZE="2"]Yes, use a .png picture as a billboard as opposed to a .jpg.

Add an alpha channel to the .png, and then you can delete whatever you want to be transparent.[/SIZE]

...alpha channel?

[SIZE="2"]Yeah.

Here's a picture in GIMP (GNU Image Manipulation Program):[/SIZE]

Hmm. Is there a way to do that in another program...say, Paint.NET?

[SIZE="2"]Not sure.

Google it to find out how (if you can).[/SIZE]

I think that this is what you want- [url]http://forums.getpaint.net/index.php?showtopic=13061[/url] -it is a plugin for Paint.NET that turns the white or black in a picture to transparent. If that isn't quite it, try this one that makes the whole picture at different levels of transparency - [url]http://forums.getpaint.net/index.php?showtopic=8318[/url]. Here's another - [url]http://forums.getpaint.net/index.php?/topic/9667-make-transparent-plugin/[/url]. (I really like Paint.NET!)

Thanks to both of you, it's figured out! :D
