Deferred lighting doesn't work on Intel HD Graphics



Reproducible only with Intel HD graphics card with latest drivers.

Reproduced with driver versions ( and ( on Intel HD Graphics 4000.
Reproduced on Unity 4.1.5f1, 4.2.1f4, 4.3.0b6;

Repro steps:
1. Open project "" submitted by user;
2. Open scene "main";
3. Go to "build setting", then "player settings".
Under "Other settings" tab make sure that "rendering path" is set to "deferred lighting".
This setting instantly changes game view (light disappears).

Attached user's repro screenshots below where he shows editor's and standalone player's bug;

Workaround is to "use Direct3D 11" or use graphics emulation (shader model 2).

    Am I being forced to buy a new machine to use deferred rendering ? Serious issue for us (Amazing Frog? ) we have been struggling with this on our build machine (MAC PRO NVIDIA GeForce GT 650M 1024 MB, but with intel HD Graphics 4000 Built -in) :/

    This also causes trouble for forward rendering, I had to do the hex edit trick on the executable renaming 'Intel' just so Unity wouldn't disable graphics features on this Intel Iris Pro 5200 GPU.

    we really need this to be fixed, on my side, the lighting somehow works, but extremely slow [DX11 Mode]

    We also really need this issue fixed. Every mac and their mother are using macbooks nowadays and every mac you can buy nowadays as an intel integrated graphics card.

    We had this issue as well while working on an Intel Graphic card, and switching to deferred rendering with directx 11 worked, however, on the same laptop, when we build the game, we do not get any shadows. On other machines not using Intel Graphics, the shadows show up fine in that build.

    This is also an issue for Hot Tin Roof. We've build a fallback to Forward shading into our settings, but it's quite weird.

    Weirder still is that Unity Editor (rendering with deferred shading) works fine on the very same machine. It's ONLY the stand-alone that completely fails to function.
