I have already enabled accurateBlockPlacement in carpetextra and also enabled carpetAccuratePlacementProtocol and clientPlacementRotation in tweakroo settings, but some redstone components such as pistons, dispensers and observers still have a wrong facing when using easy place mode
Additionally, if I turn on placementRotationFix in carpet, these blocks have the right facing when placed if their facing is either north, south, east or west and player is facing either north, south, east or west.

Server Mod List:

running on fabric loader 0.13.3
minecraft 1.18.1

Client Mod List:

running on fabric loader 0.13.3
minecraft 1.18.1

(I am Chinese and I am not good at English. I'm sorry if it brings inconvenience to your understanding.)

Thanks, this is very helpful!

its carpet's fault that only support 'certain' blocks, use this fork to support any blocks with facing :
https://github.com/aria1th/carpet-extra/releases/tag/1.4.56.3
Idk why pr is not merged until now, but it works with any modded or vanilla blocks that have proper facing values.
and I forgot... for dropper / redstone components yes its protocolVersion

Check the easyPlaceProtocolVersion config in the Generic category. You may need to switch it to v2 while on the server. If Litematica doesn't see the carpet:hello packet from the server then it won't automatically use v2 while in the Auto mode.

(The feature to automatically use v2 on a server that sends a carpet:hello packet if the config is set to Auto was added in 0.10.0, so 0.9.x would never do that.)
