Vita hanging on Unity splash screen

I've finally managed to get a game building for PSM, but whenever I try to test a build using a non-trivial scene, it hangs on the Unity splash screen. I also don't get anything printed to either the console output on PsmDeviceForVita.exe or on the Publishing Utility for Unity when this is happening. Since it never crashes (even when left on overnight), I don't have any debug information to diagnose the problem.

Any ideas?

 

I think I've isolated the problem to the Lux shaders. Strange, since they didn't cause any crashes like some of my other shaders did before I fixed them. How would I go about diagnosing the problem when it gives me no error output?

 

Had a similar issue regarding some custom shaders, except it made the initital load VERY long, it would eventually load the project.

 

The Lux test scene did open on my vita but the shaders did not look correct. There are certainly issues with how the psm beta handles custom shaders at the moment as if you use shader forge all shaders other than those that only use a diffuse input are completely black. Also the loading times for scenes that use custom shaders seem to be incredibly long. In other cases shaders that I wouldn't necessarily expect towork well on vita do. For example the SE Natural Boom and Dirty Lens shaders work perfectly on vita while even an opengles 3 android device has trouble with them.

 

I'm tempted to get SE Natural Bloom. What kind of performance are you getting on Vita PSM?

 

Toad I get about 28 fps on vita with the test scene provided by SE Natural Bloom. I mainly brought it up though because using a full screen image effect like that usually wouldn't be a good idea on mobile. Even the developer advised against using it on mobile for performance reasons. I mainly brought it up to highlight the inconsistency with how the vita appears to deal with compiling shaders at the moment. Based on it's hardware I would assume it would mainly use opengles 2 quality shaders but in some cases opengles 2 shaders don't work and in others shaders that don't even look correct with opengles3 ( As is the case with the bloom ) Work perfectly. It would be great if we had more information or at least some tips on what shaders should be suitable for the vita.

 

Yes, I had a scene containing a single object. When its shader was set to Lux Bumped Specular (IIRC), it failed to get past the splash screen even after hours, but after changing the shader to Unity's default Bumped Specular, it worked almost immediately.

 

Same problem with Shader Forge Shaders (well, most configurations it would seem).
