NGUI and multithreaded rendering

[Alessaint]

It seems that those two doesn't quite get along - when I run a game with multithreading rendering turned on the ngui panels start to flicker, their geometry gets stretched etc.

I've seen that also mentioned on unity forums - is this a known issue?

A.

What multithreading rendering?

[Ferazel]

There is a multi-threaded rendering checkbox in the Android player settings. We ran into problems with a project (that wasn't using NGUI) with it crashing so we didn't enable it. Personally, I don't think the Android multi-threaded renderer is ready for prime-time yet.

Oh, I have met the same problem.
When multithreaded rendering and NGUI are both enable, there's warped triangles flashing across entire screen.

It's a Unity bug, not an NGUI bug. It's not limited to NGUI. NGUI is simply one of the things that exposes it.

Could you add this to the FAQ? I was bitten by this too and I wasted a lot of time trying to diagnose it. (Though perhaps blatantly non-threadsafe stuff like UIButton.current should've tipped me off)

[ArenMook]

Done. And it's not NGUI-related as that thread explains. It's a Unity bug due to multi-threaded rendering being an "experimental feature" (read: completely unfinished).

Hi,

I have no crash on Android with the multithread rendering, but I have some NGUI troubles.

Is NGUI compatible with the multithread on Android ?

Thanks.

It's not NGUI. Basically run-changes to meshes are not compatible with multi-threaded rendering on Android. Unity never fixed this feature. It's a Unity bug, and there is absolutely nothing I can do about it on my end.
