Hi. There is a problem with the glass material display in humid / low
visibility weather. The material stays dark like it is not influenced by the
shader. Could you please confirm that this is a bug and if so, that there is a
chance for it to be fixed in the future?
Hello. Are the meshes on which you apply glass material separated objects? Any
particular reason why you use the MASK alpha mode over the BLEND one? Can you
show here the gltf file content regarding that material? What Blender exporter
are you using? Also, if you can provide me with a sample gltf + texture
producing the bug, I’ll use it to investigate. Regards, Sylvain
Good afternoon Sylvain! Thank you so much for a reply. We use Blender 3.0 with
a MSFSToolkit version 0.40.2.5 Window’s glass are separate mesh in one large
blender scene containing terminal. I am tried to choise different alpha modes,
but result is the same. Source files ready for export included by the link
below. Glass issue source

For reproduce problem you must place object into MSFS, Set humidity to maximum
into weather panel. Set the sun behind the object. (at the same time you will
see object and sun) With the best regards! Matvei
I was able to reproduce the problem and one of our graphics dev will have a
look. I’ll keep you updated when we figure it out.
I have seen the same issue on the glass of airport ground vehicles that come
with the sim. That was 6+ months ago so it may or may not have been fixed on
those ground vehicles since then.
Thank you Sylvain, looking forward to a potential solution.
Sylvain, just FYI, please note that when exporting via 3ds Max, the issue is
exactly the same. It does not seem to be the exporter’s problem.
Hi. Just FYI - this problem is not solved yet. Most of the time it looks
slightly better than before but still looks bad at a particular combination of
fog/time of the day/humidity. Every material with type Glass has this issue.
Hello @FlyingRaccoon . Any updates regarding this issue? it is still present and being reported by our clients.
I have noticed that using metallic in a material sorts similar. I had some water puddles that I had mistakenly set to Metallic = 1 (No COMP) and they stuck out like a sore thumb until I set metallic to 0 and just used roughness 0 instead.
Looking at some glass I have in my current project, I do not have this issue with my Hangar’s window glass. It’s using the Windshield material. Albedo is full white (#ffffff) and opacity is 0.01. Roughness and metallic are set to 0, and I do use a detail texture for scratches and etc.
The other glass I have in the scenery is on my heavy machinery models. Now, they do have the sorting issue. The material and settings are the same as above, the only difference is that I have changed the albedo color to add a bit of tint and “Don’t Cast Shadows” is checked.
I turned on Don’t Cast Shadows for my hangar glass - that had no effect. However, when I changed the Albedo color to add a tint, now they do stick out.
I guess it just cannot be fixed.
Let’s hope it is fixed in FS2024.
