in 1.21

in 1.20.1

By any chance, was the "Only affect path blocks" option on when you were playing 1.21? Or do you maybe have other mods installed?

For me, a wall like that in 1.21 looks the same as how your 1.20.1 screenshot looks, so I personally am not able to recreate the issue.

idk how to turn it on or off since there's no options in the mod menu mod, sorry for the late reply

The piston crash is likely not an issue with this mod (I even tested it just in case).
As for the lighting issue, what other mods and resource packs are you using? Because this mod should work fine with indium.

as for mods I'm using:

1. accurate block placement
2. bobby
3. capes
4. continuity
5. eating animations
6. fabric api
7. freecam
8. gamma utils
9. indium
10. iris
11. lithium
12. logical zoom
13. modmenu
14. shulkerbox tooltips
15. skinlayers 3D
16. sodiumm
17. SSPB
18. sound physics remastered
19. world edit

and for resource packs:

1. glass pane culling fix and default connected textures cus of continuity
2. vanilla tweaks
3. high contrast UI

where is the only affect path blocks option?

Options --> Video Settings --> SSPB

okay, thanks, I tried that out but it didn't work, but I finally figured out what was wrong, for some reason the mod indium is the issue, getting rid of it fixed it

so turns out, the game crashes with any piston movement and some mods don't work without indium, is there any reason the mod is not compatible with indium?

Actually, @username89213712, if it's not too much to ask, could you disable all your resource packs and tell me if that fixes the issue? With the set of mods and resource packs you posted, the resource packs were the issue for me. It probably also is the issue on your end, but confirmation wouldn't hurt.

Seems to have to do with Continuity. Seems that mod starting from v3.0.0 forces every block to use indium if even a single connected texture is present. This basically means all blocks bypass this mod, so SSPB doesn't do anything but set path blocks to use the vanilla lighting algorithm in indium. If this is what's causing the issue for you, then its related to #25.

A partial workaround for now would be to go to .minecraft/config/indium-renderer.properties and change "ambient-occlusion-mode=auto" to "ambient-occlusion-mode=hybrid" or "ambient-occlusion-mode=vanilla". Note that this is only a partial workaround because SSPB options still won't affect anything in this scenario.

Under the testing I did with your mods and resource packs, I'm pretty confident this issue is solved in 7f5b76a, with release 3.4.0. If you're still having this issue, feel free to reopen.

Remember to set "ambient-occlusion-mode" back to "auto" in indium-renderer.properties if you changed it to "hybrid" or "vanilla" previously.
