Glass reflection missing (Sketchup, enscape 3.3.1)

florin_nistor · Aug 30th 2022

Greetings again,

I'm facing the following issue. Reflection is missing from several glass panels, even though the family is correctly created and have no flipped normals in the model mesh. Attached is the glass panel configuration and material setup, also an export from sketchup (white as proof we don't have no flipped normals) and a draft image from Enscape.

Issue is present on multiple versions of Enscape, 3.3.1 and 3.4 even 3.5.0 preview version.

Attached in link is the window family which we use in the 3D model: https://we.tl/t-lYBWlIcmdc

Awaiting your response, thank you.

florin_nistor , thanks for your report and also for the test file - As far as I can tell it may simply be the perspective that renders the reflections less visible than desired. If you move closer to these glass panels, are you able to see some reflections at all? If not then perhaps you could also share the whole scene itself? With the already attached file, I cannot see any problems, but my question is also, do you experience missing reflections in that test scene too?

Thank you for your input.

Moving near the respective panel or in front of it still shows no reflections.

Yes, even in the test file, only those panels have invisible reflections.

But I made a trick by setting the Roughness to 5% and now all reflections are visible.

florin_nistor this particular issue has been fixed with 3.4 - therefore 3.4 and newer versions should not show this behavior anymore.

Here's the file you've attached with and without the glass - you can clearly see the reflections when the glass is present.
