Atlas Maker weird problem

[CatChop]

Hi,

We're trying to build a 1280x720 picture into an atlas,
sometimes it worked, but sometimes it was not. (with no error message)
if failed, when we click on the atlas, we will see no sprite information in the inspector,
but material and texture seems fine.

We build all the atlases in the same way,
really have no idea why this happened...
We also have tried jpeg, png and even psd.
Another 1280 x 720 picture also has the chance to fail.

The NGUI version is 2.6.3.

Any information would be helpful, thank you!

First, don't add such a large texture to an atlas. Atlases are for small textures, not such large ones.

Use UITexture to draw this large texture instead.

Second, 2.6.3 is no longer supported. It's very old.
