Lightmaps blowing out

Im having some nagging problems with lightmaps blowing out in my project.

The lightmaps look good when its finished baking, but if i turn off "continous baking" after its baked and then press play, or restart unity, everything gets completely blown out and way too bright.

I attached a screenshot to show what im looking at:

I must be doing something wrong but im kind of stuck at the moment and would be very happy for any advice how to fix it.

 

Hello KEnglestoft, thanks for replying!
Im using the standard shader for everything in the scene except for the terrain, which uses a bumped/specular terrain shader.
I tried rebuilding it from scratch, and rebaking but im still getting the same result.

Edit: It must be a problem with my hardware because i get the same result in a fresh project with only one object in the scene. When continous is set to off the lightmap will go white when i press play:/

 

i had the same problem yesterday. it was a scene i imported to the beta13. i changend the shader to the new standard with no luck. i will start a new project today and see if the problem is still there..

 

That would be great, ive not had any luck getting around it yet. If it means anything my graphics card is a gtx 670.

 

I have also the same problem. I don't know exactly when it happens but sometimes my scene is completely white. When I rebake the scene, it goes away again.

 

Submitted a bug report, case is 651470.
It happens in a new project with no packages imported so I didnt include any project files.

 

This is occurring with me too; I'm using the Mobile Shader set (mobile->diffuse, mobile->bumped specular, etc.). Is that expected?
