Standard Shader Emission texture not showing on all instances.

Questions & Answers

I´m finding it weird that I have a material that I added emission texture and it worked just like it´s supposed to. Then the same material on an another instance lightmapped under same conditions doesn´t show up emission with this texture, but do works with every other texture I put in the slot.

So question is simple, is there something that I´ve missed about global illumination or such?
As said material emits light only on random instances so could it be issue of lightmap UVs or normals?
Although inserting another texture works so that is bugging me…

Are all of the objects you’ve applied the material to marked as Lightmap Static?

Mystery solved, TOTAL my bad… The diffuse texture had two similar areas both representing the same area and only one was textured with in emission map. On the master file there must have been somekind of false layer ON so I thought it was using one area for both sides to save optimize texture density and maximasize resolution on mobile. That´s why there´s no light emission on those areas. I´m really sorry for wasting both of our time. Call this one solved.
