Pink Interface on Some Machines

[PickySalamander]

Hey,

I've been using NGUI for a while now and this is the first time I've come across this error, which is a strange one. On a certain machine of my client's company all the NGUI interface displays as pink boxes. I know when textures don't display properly in Unity they show up as pink. This though appears to only happen on a couple of the 50 machines my application is on. The one machine they let me look at is pretty ancient and I suspect the graphics card just can't handle the shader used. I wanted to see though if there are quick things I can do to resolve this problem.

Here are Unity specs:

Unity 4.2.1f4
NGUI 2.7.0

I attached a DXDiag screenshot to this post of the machine that is having problems. I'm trying to get a Unity log from them as we speak, I will post that when I get it.

Thanks!

If it shows pink, it's almost 100 % certainly that the graphics card doesn't support the shaders used.

Yeah I figured that maybe the problem, but I wanted to do some due diligence before I gave up completely. I finally got the Unity log from them and it's attached. There were a couple interesting messages in this log:

• Unsupported: Hidden/InternalClear
• Unsupported: Unlit/Transparent Colored
• XInput1_3.dll not found.

The last of which I think is a DirectX problem, which I'll have them re-install. I assume the two unsupported shaders are the ones NGUI needs in order to render properly. Would the missing dll cause the two shader problems?

Pull the Unlit/Transparent Colored shader from the 3.X version. It re-adds the fixed function pipeline support.

Your videocard basically doesn't support shaders. This usually also happens when your quality is set to "fastest", as that too disabled shader support.

Thanks, I'll give that a try and see if it works.

I updated to the most recent version of NGUI and everything seems to work fine now. Thanks for the help!
