Question by sxkx360 · May 06, 2016 at 03:41 PM · emission

Standard Shader Emission texture not showing on all instances.

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...

Here are pictures from same object and from both ends of the corridor. It is using the standard shader. As you can see other one is working and the other is not.

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.

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

Yep, default all static checked, that´s also why it´s bizarre, also rebaked lighting to check if it helps. With every other texture it works so maybe I just try to create a new texture until that it shows in every facet, could it be just an issue with texture opacity, format or color mode?

Opacity perhaps. I doubt the format or color mode would have much of a difference.

One more thing: make sure the float value next to the texture in the material settings is not zero. It multiplies the emmissiveness by that value.

If that doesn't do it, can you post some screenshots of the problem and the material settings?
