3.1b8 GLES 2: Sky emission seems to have disappeared. #26372

Closed gau-veldt closed 4 years ago

gau-veldt commented 5 years ago

Godot version:

3.1b8 GLES 2

OS/device including version:

Windows 7, DXDiag reports: "Intel(R) HD Graphics Family"

Issue description:

Game last ran in beta 3 had no directional lighting (scene has a single directional light) but got sky contribution (world had blue tinge from the sky). In b8 things went opposite: directional light works but now world is completely black (no more blue tinge) meaning the sky contribution is gone.

Adjusting the ambient/sky ratio didn't fix. If it's set to 100% sky as I mentioned world goes black (with directional light disabled).

Steps to reproduce:

Create a 3D scene. Add a mesh (CSGBox should work in a pinch). Add a directional light. Add a camera and set its environment to use default_env.tres Verify the sky is procedural, etc etc etc (the way it is in a new project's default_env.tres anyways) Disable the light so any light in the scene has to come from the sky. World is black (no sky tinge).

Minimal reproduction project:

Likely related to #25512.

Given that it's quite rare and old hardware, I'll move it to 3.2 milestone for now, but ideally we should be able to find a fix/workaround quickly and backport it to the 3.1 branch.

Example project works fine here with Godot 3.1-b10, Geforce 940MX.

Windows 7, DXDiag reports: "Intel(R) HD Graphics Family" Geforce isn't an Intel HD chipset

Sorry, it's an Nvidia card. Probably should have specified that.

I specified in the issue this laptop has Intel HD chipset. It's a chipset/GLES2 issue most likely. Intel's are notorious for having hideously coded Windows drivers. The chips are much more functional in linux under linux drivers.

Is this reproducible in 3.1.2?

Calinou commented 4 years ago

@gau-veldt Bump :slightly_smiling_face: See @clayjohn's question above.

gau-veldt commented 4 years ago

Standby by on that one... I have to make sure I test on that laptop against a 3.2 build.

Calinou commented 4 years ago

@gau-veldt Could you test this in Godot 3.2rc3, please? (Note that 3.2rc4 is around the corner. It should be available tomorrow if all goes well.)

Calinou commented 4 years ago

I'll close this due to lack of response.

@gau-veldt I can reopen this issue if you confirm the issue is still present on 3.2.
