I always get warning on General GI in Lighting window.

“Directional lightmaps cannot be decoded on SM2.0 hardware nor when using GLES2.0. They will fallback to Non-Directional lightmaps.”

Any idea?

Thanks.

HI,

The warning comes once you upgrade your Unity to 5.3 version. It was because of a lightbaking issue on previous unity 5 version reported here: Unity Issue Tracker - [Shaders] Missing fallback from Directional to NonDirectional mode with shaders that do not support it (GLES2.0/SM2.0/DX11level9.

The reason is Unity have some lightmapping issue using GLES2 as baked lightmaps not showing on android and mobile devices . You can find more on this link: http://forum.unity3d.com/threads/baked-lightmaps-not-showing-on-mobile-device-ipad-android.310945/

Your unity settings graphics have open gles 2 and to be honest i dont know why there is a hardware warning. Unity should clarify it more.

Let me know if you have lighting issues on your mobile. I will be happy to help.
