Unity 5, GI with small objects

Hi there,

I'm encountering a prob with emission on Standard Shaders.
All is working fine until I scale down the emitting object... suddenly, the light emission is not rendered anymore.

You could easily reproduce this with a simple emitting cube in a empty scene with 3 walls.

The prob is occurring with small objects too, not scaled.
Is there a limit of size for object to emit??
I tried everything to change GI settings but always the same result.
When I scale up a small object then the emission occurs.

Any idea?

Thanks, Q.

 

Have you found anything out about this? I have the same question, haven't been able to find an answer.

 

The secret is to do your UV2 by your self and counting on "Generate Lightmap UVs" from Unity.
My scene and objects are much better lighted now, look
