Title: Problems with NGUI Atlas Generation in Version 2.5.1 Standard
Post by: DCalabrese on April 20, 2013, 11:27:57 PM

I've recently upgraded to v2.5.1 Standard, and I'm finding that the atlases now take upwards of 15 minutes to generate (instead of 35 seconds), and the quality of the final image does not reflect the quality of the original images (the new Atlases are very grainy, rather than being very crisp like in previous versions). I'm also finding a lot of other issues with this release, including you can not turn the camera while a NGUI object is selected, moving objects is very difficult (as it randomly seems to now rotate or scale instead of move), selecting and moving multiple objects is very problematic, etc.

Is anyone else having these problems (especially the Atlas generation issues)? If so, is there any way to acquire previous versions of NGUI?

Thank you!

I pulled NGUI 2.2.3 from another project and downgraded from 2.5.1 to 2.2.3 and all the problems went away. Does NGUI 2.5.1 no longer support Unity 3.5.7f6?

That sounds weird. 3.5.7 should still be supported. Does it downscale the atlas? Maybe your quality settings are defaulted to fastest or something? :S

2.5.0+ changes the way you interact with widgets. Watch the updated tutorial video to see how to interact with widgets now.

The atlas is downscaled, yes. It's final quality was terrible in the new version. It also took a very, very, very, very long time to generate - about 15 minutes (not joking). As soon as I went back to the older version, the exact same sprites generated an excellent, crisp and clear atlas in about 10 seconds.

That sounds like it was PVR compresssed with Best Quality and resized to tiny. The PVR compression is the only thing I've had (apart from importing lightmaps, which is essentially the same thing) that has taken a crazy amount of time.

Is the atlasmaker using Unity's texture packer or the custom one? What are you quality settings actually?
