Scattering Plugin Appears Broken - Only black screen showing when it is enabled

[typewriter1]

I have had this working for me before, but I just updated to the latest master and RenderPipeline works better now (lights did not work, I got an error about IesDatasetTex (actually, there is no error any more, but lights still have no effect)).

However, now, when I run the samples with only scattering enabled and using either eric_bruenton or hosek_wilkie, all I see is a black screen with some white for light.

Windows 10, Intel GPU.

Do you get any errors on the console? Also, Intel GPUs are known to cause trouble

I get the warning [!] Panda3D :linmath(warning): Tried to invert singular LMatrix4. even with scattering disabled.

Is this intended to run on Intel GPU's?

[ghost]

I have an nvidia gpu and I also have problems with scattering. I get these errors

[ohouha]

@typewriter1 right now I got same issues, Do you get any solution?

[typewriter1]

No

[222464]

AMD GPU, Manjaro Linux. Same errors, I am guessing there is no fix yet?

Mesa OpenGL spec doesn't allow extension to be defined in the middle of a shader, so I think:

This could be fixed by moving defined extension:

#extension GL_ARB_shading_language_420pack : enable

from

rpplugins/scattering/shader/eric_bruneton/scattering_common.glsl

to

rpplugins/scattering/shader/apply_scattering.frag.glsl

and placing it after the line

#version 430

So can we close this?
