I created an “Emissive” material and set a texture, but it is not shown at the rendered viewport. Also it doesn’t help to push it per “show in viewport” button. I added a diffuse layer, but the same problem. So, I created a generic material and added the map to the diffuse color - it works. I added an emissive layer with texture - texture isn’t shown anymore.
Thanks for pointing this out.
We have just started reviewing the material/texture ‘binding’ logic and this is one of the edge cases.
It should be resolved in the next update.
