No shadow casting and some odd poly-fill issues

    Hi there,

    This video shows the problems I experiencing:



    In the process of exploring the lighting issue I reduced the scene to a single directional light position straight-down onto the map and deleting the baked shadows. As you can see, the ball never casts a shadow onto the floor.

    Also, the floor itself seems to disappear at times. Looks like an issue with the fragment shader, as this floor is only two triangles!

    None of these issues appear in the webplayer build this project was originally intended for.

    Are these known issues?

    Thanks.

    Hey, I haven't tried real time shadow in my project but people have seen the issue of objects random disappearing when looking at them at a certain directions, seen here and here.
    Also, I strongly advise you to go to Help -> Report a Bug.

    Check your quality settings. The first time I deployed my project on the Vita, I was missing shadows too, along with various lighting effects and I got lower resolution textures. Turns out the project's quality settings were set to Fastest by default for PSM, which intentionally gets rid of a lot of detail. Cranking up the quality to the same level as Standalone and Web Player fixed the issue for me.

    My shadows only appear now and then, might also be to do with the camera. :)

    Yeah I was also thinking this this morning, since my PSVita build of WillG's Stealth tutorial seems to throw shadows (albeit at around 10 fps). I'll try some quality setting changes tonight, and if I'm sure it's a bug then I'll report it as such.

    Thanks for your feedback everyone.

    Yeah, that sounds like my disappearing floor bug alright. Glad to see this forum is more lively that PSM's.

    Hi cubusaddendum,
    I've been trying to re-create your missing shadows, do you have a custom fragment shader on the floor? or do you just mean the generic shader? Is there anything else special setup with your ball or the floor?

    If it could be possible to send me the scene with broken shadows it would help a lot :)

    Hi Graham,

    Thanks, I'll put the scene in my dropbox tonight and PM you the link.

    It's using the generic shader. When I played with the quality settings I managed to get the shadow working around the origin of the scene, but there's a clear boundary beyond which shadows stop appearing. I'm using a single directional light source, and have tried moving it around (and even adjusting the cookie size, although I'm not using a cookie) without affecting any change. Am I being dumb?

    Again - this is incorrect. Fixed function shaders are supported with Unity-for-PSM, on PS Vita.

    Sorry, I didn't realise. I've been using the other vita - I guess they're different.

    He means the other SDK - the native one. ;)
