Atlas texture generator?

[jaguard]

Is there a good software to pack textures onto one atlas? I've been googling this for a while, and still haven't find anything. PC or MAC, and it should save texture coordinates in a separate file somewhere, so I would be able to read it. XML, plain text or binary would do.

There's some strange tool by nvidia, but it's for compressed textures, I however need pngs with alpha.

Theres a free app called Mappy, just google it, it should do what you want, although as name implies it's main purpose is to create tile maps, but it can be abused to do what you describe, other than that, I use Gimp/Photoshop, is painful doing UV offsets by hand but it works....

Worst case...you could always use the nvidia tool and convert from dds to png.

Hmm... I think Smithdale was working on a custom one; maybe he can weigh in on this.

I was unable to find this feature in mappy. Could you give more insights where I should look to? Photoshop is cool, but not when you're dealing with 1000 of frames. Also, it won't be able to find the optimal placement.

Even if I was able to make use of that utility, I wouldn't want it - dds is compressed format, and it's not lossless, so I would lose quality from this conversion.

Hi,

we wrote an atlas generator script. It generates an atlas from multiple input files, doing the layout automatically.

You can download it at zombiesmahs.gamedrs.com. (Section Development)

It was written to use with the Cocos2D framework. But it is very easy to change to anything else.

Hope some of you might find this useful.
