UIPanel clipping went haywire

[Nicky]

All NGUI GameObjects under my UIPanels failed to display properly when any clipping is defined. Any UISprite or UILabel under the UIPanel would be displayed as a solid block until I remove clipping on the parent UIPanel.

This used to work perfectly until I was fiddling with some 3D assets (mostly textures and shaders) and project settings for optimization for mobile. But it was too many and I could not figure out what caused it.

Starting new scene had same problem.
Restarting Unity had same problem.
Restarting new project was did not have the problem.

Before I have to restart the entire project or undo all the optimizations... would anyone know what setting could have caused this? A faulty shader? Everything else works fine.

Thanks in advance!

I also tried reinstalling the latest version of NGUI. Seems to be something else in the project settings.

Had a stray line when I was experimenting with the globalMaximumLOD and forgot to remove it.

1. Shader.globalMaximumLOD = 100;

Removed this and it was fixed.

Weird that the problem was showing up in the editor without this code running at all.
