A change was introduced in 7.3.5 that causes the game to crash upon loading a world when shaders are enabled. The game loads to a screen with a triangular shape, then it crashes.

The issue is not present in 7.3.4, so I have downgraded to that for the time being.

Forge: 40.1.54 (OptiFine has issues with the current release, so test against this build)
OptiFine: 1.18.2_HD_U_H7
Shader: Complementary Shaders 4.5.1

Also tested against Fabric 0.14.8 and Iris on Minecraft 1.19.1, similar behavior

Optifine being funky again, I will take a look at this

So, I can give some updated context for this. This issue is occurring against Iris on 1.19 as well, but the thing is that the issue doesn't appear on a consistent basis. I have used Complementary Shaders for my testing.

It has materialized on some first-run singleplayer worlds, and it has worked fine on others. I have loaded up two packs with the exact same set of mods. It'll work the first time, but after closing down the pack, it will crash on the second time, or some combination. As I said, it is not consistent...with one exception.

This error is consistent if you attempt to join a multiplayer server.

This issue should be fixed in newer optifine releases, please reopen if still present in the latest mca version

Since you are the 100th person asking for villager conversion after world gen, I will add this as a command :)

thank you

Nope, it most certainly isn't fixed. It keeps loading to this:

It seems to be able to figure out the in-game time of day, because usually it's on top of a bright background, but this time it was dark. Regardless, this issue is very much still present. I have updated to 7.3.20 and OptiFine 1.18.2 H9 pre1. "Telkit IV" is a pack maintained by me. It is also present in my "NosiFabric" pack which is Fabric-based on 1.19.2, using Iris 1.2.8.

Please reopen as this is not fixed.

@seancrain Send us a link to your pack, and we'll reproduce it from there

My packs use MultiMC and Packwiz, here are the installation instructions:
https://modpack.nosiphus.com/installation-instructions
The packs in question are Telkit IV and NosiFabric. I have not updated Telkit III, which is 1.16.5-based, to the latest MCA Reborn build yet, but I suspect it will likely happen there too if I do.
I will keep both the Telkit IV and NosiFabric servers up so you can see what happens there. I cannot for the life of me figure out what is causing the crash, hopefully you guys can.

Notice that I just fixed a very similar error, maybe try 7.3.21.

It isnt up yet for 1.16.5 Luke, but given whats going on I'll push a RC for 1.16.5 and 1.17.1 as well

I'll have to wait for those builds to hit Modrinth, but I will update as soon as they do

Disabling the villager player model caused the crash to return because it wasn't happening before I set the configuration settings. I think that's probably what is happening.

Then that clears it up. Do you have an ETA on when those builds will be out for 1.16, 1.18, and 1.19?

Then it's the issue I link!

sometime today, 7.3.21+rc.1

Alright, I'll be waiting. I'll have to delete the server map and WorldEdit everything back in, because I don't think existing villages will be overwritten with MCA villagers (correct me if I'm wrong), but I'm glad I can finally play this mod again!

@seancrain 7.3.21-rc1 is now being released as we speak, please test on that version and let us know if things are resolved on your end.

It loaded with no crashes. Thanks, guys, issue has been resolved.
