Iris 1.8.0-beta-3 breaks Complementary Unbound 5.2.2's "Show Light Levels" feature.

To be sure I created a fresh new MC 1.21.1 instance with Fabric 0.16.3 loader, ComplementaryUnbound_r5.2.2 shaders, and only the following mods: - Iris 1.8.0-beta.3+mc1.21.1 - Sodium v0.6.0-beta.1+mc1.21

Solution:

Fixed in Complementary Shaders v5.3

Can you describe your issue in further detail? Does it simply not showing up when the option is enabled, the shader crashed, it showing up wrong or other?

MusterionOP•3mo ago

It's just not showing up, as if enabling it has no effect at all.

hardester•3mo ago

No in-game chat errors or anything I assume?

MusterionOP•3mo ago

Rolled back to Iris 1.73 / Sodium 0.5.11 and it works fine. no errors at all that i could see.

Share your game log so that I can take a look at what's going on. Preferably, upload your log to https://mclo.gs as it makes log reading easier and help hide away any sensitive information.

How to get crash reports and logs

It is highly advisable you upload your crash reports and logs to https://mclo.gs/ then share the link in Discord for easier reading and censoring potentially sensitive information. Otherwise, you can drag and drop the file directly into Discord. Crash reports can be found in the crash-reports sub-directory in .minecraft on clients, or the crash-reports sub-directory of the server directory for servers. We're probably interested in the most recent file. Logs can be found in the logs sub-directory in .minecraft on clients, or the logs sub-folder of the server directory for servers. We're probably interested in the file named latest.log.

OK will do, ty Anything I need to redact for security?

hardester•3mo ago

Mclogs does it for you. It is an open source project by the Aternos team to help making reading Minecraft logs easier and more secure. Also, usually the game logs and normal crash logs doesn't contain confidential information. Native crash logs do have it, almost a guarantee.

At line 108, there appears to be information relevant to the shader pack. It appears there's an error happening when the option is disabled, rather than enabled. With that said, take this log to Emin (Complementary shaders' developer) so that he can take a look. For now, I'll leave this to IMS to investigate on Iris side.

MusterionOP•3mo ago

OK, will do. Thanks for the help.

@IMS the problem is that this function no longer returns any value below approx 0.03 now with the latest iris

    vec2 GetLightMapCoordinates() {
        vec2 lmCoord = (gl_TextureMatrix[1] * gl_MultiTexCoord1).xy;
        return clamp((lmCoord - 0.03125) * 1.06667, 0.0, 1.0);
    }

    vec2 GetLightMapCoordinates() {
        vec2 lmCoord = (gl_TextureMatrix[1] * gl_MultiTexCoord1).xy;
        return clamp((lmCoord - 0.03125) * 1.06667, 0.0, 1.0);
    }

I think this problem makes every shaderpack have a slight bit of blocklight everywhere in the world

IMS•3mo ago

I'll take a look at it, but that function seems weird? what's the subtraction and stuff for :ioa:

Emin•3mo ago

I don't know but it's common practice in a bunch of shaders :tiny_potato:

IMS•3mo ago

that looks suspiciously like how the game itself clamps which is... wrong :ioa:
