Question by boxheadproductions · Apr 13, 2017 at 03:17 PM · iossplash-screen

Purple colour on screen after custom splash iOS

I've recently upgraded to Unity Plus and have a custom splash added (it is just a logo with static animation set). The splash lasts 5 seconds. After this time just before loading the menu scene (which is fairly small I might add) I get a few frames of bright purple. I don't see this in the editor obviously so am having trouble finding the cause.

My assumption is that the scene hasn't loaded and the purple colour might be the result of that.

How can I test? I'm getting nothing useful out of Xcode.

I am running iOS version 10 and Unity 5.5.3

EDIT: This only occurs on the FIRST run of the application. Even killing the app through iOS and running it again will produce a smooth transition. Restarting the iPad after killing the app will produce the purple flash again. Subsequent runs do not produce it.

I am sometimes getting this even with the "stock" Unity splash screen. Are you doing quality/resolution changes in the code when the scene loads? Are you using $$anonymous$$etal or OpenGL?

While I am not an expert, here is something that may help Purple/pink could be a sign of a shader issue - possibly falling back to a default shader instead and only why it flashes?

as to why it doesn't happen all the time and only on first run - again is a guess but sounds like a caching system on the ipad? try loading a base scene with nothing in it first (or maybe a black plane or something) and loading the main level asynchronous
