Everything rendered in black

[typewriter1]

When running, whether I use sublime, mediocre or terrible quality, the game shows up only how it does in this screenshot:

Apart from this, it appears to be an excellent game though, with good graphics (at least from what I can tell from the screenshots). I am using Windows 10 with an Intel HD Graphics 630 GPU, which should theoretically support up to OpenGL 4.5.

I think this has to do with a certain color shader input not working correctly on this specific GPU series. Oddly, I've not been able to produce it on my own Intel HD Graphics 620 on Windows 10, but I have seen it with an identical GPU on a different machine.

I suspect a driver bug, but maybe we can find an adequate workaround.

[typewriter1]

Might this also be the cause of this issue I am experiencing with RenderPipline?

[rdb]

Might be. Impossible to tell for sure without further debugging.

@typewriter1 If you have time, could you maybe do the following?

1. Attach the output running with notify-level-glgsg debug
2. Record an apitrace file and attach it
   In both cases it's only needed to run it long enough to reproduce the black output, in order not to create an unnecessarily long file.

I have a few ideas in the back of my head of what might be causing this, and these two bits of information might help me confirm it.

Unfortunately, I am unable to work out how to use apitrace.

I don't see p3d_Material.diffuse at all in the shader input reflection info in the log. That looks like a big red flag to me.

This is a shot in the dark, but I'd try opening assets/shader/lighting.frag in a text editor and changing the first line of this:

uniform struct {
  vec4 ambient;
  vec4 diffuse;
  vec3 specular;
  float roughness;
} p3d_Material;

to uniform struct p3d_MaterialParameters {.

That did not solve the problem.

Are you sure? Did you change it in the right place? I made that change on a computer that I reproduced the problem on, and it fixed the issue. Note that if you run it from source, there is at the moment (unfortunately) a duplicate shader in game/assets/shader/lighting.frag.

[typewriter1]

Changing both shaders gave me an error on line 32, when accessing the value of p3d_Material.diffuse.

However, replacing it with this fixed the problem!

struct Material{
  vec4 ambient;
  vec4 diffuse;
  vec3 specular;
  float roughness;
};

uniform Material p3d_Material;
