Transparency Reflections in 4.12?

It looks like you have no object to reflect in the scene and did you add an cubemap?

There was a sphere reflection capture in the scene, but also two errors from me:

  • the sphere reflection capture didn’t work because there was no SkyLight object.
  • the opaque material had a black base color.

I updated to 4.12.4 and added a SkyLight object in the scene. This is the result:

As you can see, the sphere reflection capture object + the SkyLight object allows the opaque object to have reflections, but still no reflection on the basic glass material configured
Then, I tried to add the fantastic “advanced glass material pack” bought from the marketplace, and then… here there are the reflections!

So my question now is: why reflections didn’t work with the “basic glass material with reflection” suggested by the Unreal official guide? Need to update that help page? What is the minimum material configuration to achive reflections on the glass?

I tried to type r.ForwardLighting=0 or r.ForwardLighting=1 into the console while in Play mode, but nothing happen. Am I doing something wrong to follow your suggestion?
