Error after build from source: Vulkan setting(?)

[lee-deraud]

(Be gentle with me, it's the first time I've ever tried this...)

Finally managed to do a build from source, using Visual Studio 2022, and the latest CMake. Everything appeared to work ok, installed it on miniconda, and started a known good script:

(base) A:\3D\Scanner\Orient>python -m OrientExpress foo1.stl
FEngine (64 bits) created at 0000016521A11E50 (threading is enabled)
FEngine resolved backend: Vulkan
Vulkan device driver: NVIDIA 576.02
Selected physical device 'NVIDIA GeForce RTX 3060' from 1 physical devices. (vendor 0x10de, device 0x2504, driver 0x90008000, api 1.4)
Backend feature level: 3
FEngine feature level: 1
The stereoscopic type in the compiled material 'Filament Default Material' is 1, which is not compatiable with the engine's setting 0.
The stereoscopic type in the compiled material 'defaultLit' is 1, which is not compatiable with the engine's setting 0.
The stereoscopic type in the compiled material 'defaultLit' is 1, which is not compatiable with the engine's setting 0.
The stereoscopic type in the compiled material 'defaultLitTransparency' is 1, which is not compatiable with the engine's setting 0.

plus a dozen or so very similar messages. I don't recall ever seeing messages related to Vulkan or NVidia using the stock downloaded 0.19.0. What I usually get is this:

(base) A:\3D\Scanner\Orient>python -m OrientExpress foo1.stl
FEngine (64 bits) created at 000001C66CCB0050 (threading is enabled)
FEngine resolved backend: OpenGL

The script itself started fine, did its usual output to the console and then displayed a solid black window.
I don't recall ever seeing messages related to Vulkan or NVidia using the stock downloaded 0.19.0. I suspect a switch set wrong somewhere: I just left everything as defaulted, using the build instructions in the docs.

Any suggestions on where to start looking?

[UPDATE] Discovered that this poblem also affects the 'Open3D.exe' and 'Open3DViewer.exe' (same program, I think) compiled during the build. Also get this compiling on a different machine using VS2026. Next step is to install the newly-build wheel on yet another computer (without Nvidia GPU) and see if it behaves differently.

[UPDATE 2] No joy: On the other machine, it detects the Intel integrated graphics as the only GPU, and throws the same errors.

(plus a similar error for every compiled material)

Apparently a Windows-only problem, fixed as of PR #7444. See issue #7446 for details.
