Lightmap problem or something else in unity 2017-1

[blackant]

Hello,

today i imported my project into the new unity version
ihve got some messages about lightmap incompatibilities so i recreated them and it worked for 2/3 of my scenes

and inside the problematic scene i have major objects that are completly white…
i tryted to modify lightmap, checking all materials but they seams to be like they where before i bake the project here.

so the strange thing is:

• i can modify anything without any modification result
• the cylindric plane is not set as static so it would not be affected by lightmap, so i assume the problem may not come from lightmaps.
  deactivating the emissive parameter in the shader doesn’t affect anything.
• the cube is a room affected by lightmap
  there is multiple materials on it, no one is displayed correctly
• inside the room , some objects were correctly displayed but now noone is correct (as you see selected one)
• trees are not affected by the problem
  
  
  
  This is the albedo map:

this is the Light Overlap wich is the most accurate from what we have in the rendered camera

selected object

well, i fund the answer finally and it was not a bug.

the new shader is proposing a reflection parameter wich must be disabled to get back to the previous and good render i espected

Finally the problem is not completly solved,
after deactivating all reflections parameters in shaders, i get everything displayed in black when i generated new ligthmaps
reactivating reflections corrected everything !
but :
i closed unity
i get crashes
and i get again white objects but not everywhere

i made some investigations to understand
the miror made by ciconia studio, is using defered renderer
i modified my camera to see if it can be related to it,
and here is what i get when i put my camera in defered mode

and from far here is how it looks:

this is extremly bizare, the white part is not a mesh but something related to lightings,

i have no idea

i made a new lightmap and this time, object who where good are white, some are correct and some are white…

this is driving me crazy

so i decided to delete the folder containing lightmaps for this scene and i get all back to normal, i’ll try to build new maps…
