Shadows render from the wrong direction with Optifine shaders about flywheel

[Duorhs]

I got the same issue, and after standing a few second my game even crashed...Here is my log
Creators-of-Create/Create#2064

@Duorhs I had a crash like that too, but it was likely caused by using the wrong version of selene with supplementaries. I've not seen it since fixing that, with a few hours of playtime.

You seem to have a lot of other mods installed, I think that crash is a red herring and unrelated to this - try and isolate out just the mods causing the behavior, it's nigh impossible to debug otherwise :)

Thanks for reply , I play with a lot of mods , but everything is fine until I update Create & Flywheel , Thermal Series and Better Foliage and CraftTweaker today. However, my game crashed after it loaded so the world was saved with these newer version mods. I tried to start a new game , it didn't crash . But downgrading these mods and load the old world will be another type of crash. So I can't ioslate it with my old world...

@Duorhs You've not tried everything yet!

The error seems related to create's belts - read the first line of your error log ;) So maybe you need to have placed at least one of those.

If that's not enough to isolate the mods, try the following:

1. Create a backup of your world (!), and never open this one directly
2. Create a copy of your backup
3. Disable all mods, except create + flywheel
4. Start the game and enter that copy
5. Play until you see your crash
6. If no crash occurs, repeat steps 2-6, except enable another mod you suspect in step 2

• In your case, try these mods in order:
  • Thermal Series
  • Better Foliage
  • CraftTweaker
  • Optifine
  • Any other mods you have

7. Whenever you do get a crash, start the game with just create, flywheel and the mod you just enabled

You'll eventually reproduce your issue :) The trick is keeping an untouched copy of your world, so that your mods can screw up however much they like.

Once you have isolated the mods causing the issue, create a new issue with those. I doubt it will be related to this issue, though the error message does suggest that create is involved. Don't think shaders care much about the block facing direction, so optifine is likely not the culprit.

If this seems like a lot of effort, yes, it is!

The reason this is important is because the mod authors would have to go through exactly this procedure to figure out what's going on anyway, but they don't even know what mods you're running. Even if they did, it's a long process and they have more important things to look at, even if they're doing this full-time and as paid work. So do your part and help produce an exact reproduction scenario - it's an open source project after all, contribute what you can if you want something improved!

If you can only reproduce it in your existing world, you may even need to upload a copy of it.

Anyway, all of this discussion is irrelevant to this particular issue, so feel free to continue it on Creators-of-Create/Create#2064.

Thanks a lot, this gives me clear and simple ideas to figure out the problem, I'll find time to try it out!

While I was doing some work to test, I noticed that my issus in Create has been addressed. I built the mod with the latest code and it didn't crash (by Create) any more...However the shadow issue as this topic mentioned at first is still there.

Fixed in latest create/flywheel, this was a weird one for sure

Thanks!
