Emissive materials are not illuminating other objects

[leduyquang753]

I have made a small scene involving an emissive screen (DwaEmissiveMaterial) behind a glass pane (DwaRefractiveMaterial). When rendering, the screen itself is visible to the camera, but other objects are not illuminated by it at all (when the light in the scene is removed, the whole rendered image is black except the screen). I have tried assigning the DwaEmissiveMaterial as both surface and volume shaders. Also, if the glass pane is removed, the screen disappears entirely, as if the screen is only visible when looked from the camera, through the glass pane. I'm not sure if I'm missing some things to be configured.

The same scene rendered in Blender, for comparison:

The scene's data: MoonRay scene.zip

Platforms used:

• CentOS in Docker in Windows subsystem for Linux.
• CentOS standalone.
  Both MoonRay instances are built according to the instructions in the documentation site.

Lying on the bed at midnight, I just realized the layer has the phone object twice, one with the whole mesh, assigned the body material and one with the individual parts assigned their corresponding material, as a result of the export from Blender with vertex groups. Probably this is the cause of the issue, I will try after 8 hours when I wake up.

There is indeed duplicate geometry. I had to manually assign the remaining faces of the phone object to the Body part and remove the whole object reference from the layer. However, the screen still only illuminates when the glass pane is not present: if I remove the glass pane, it illuminates to the front; if I remove the body, it illuminates to the back. I have tried setting priority to the phone object's materials, which didn't seem to fix the issue. I ensured I didn't have the parts overlap when I originally modeled in Blender though, so that was just a check to make sure; manually inspecting the coordinates in the scene script showed the vertices are at the correct positions.

In short, the glass pane currently seems to block indirect lighting from the screen.
