make sure you post the full log, in this case the launcher log is also helpful

you can handle this via a Capability which is synced between server and all clients, for example, the Player "x" select Model "y" in your Gui, then send a Packet to the server which sets the Model of Player "x" on server to "y", after that sync the Capability update to all clients means all clients know now that Player "x" use Model "y" last but not least render the Player "x" with the selected Model "y"

i'm be able to reproduce this error, i have know idea why this happens but seems to be a bug with modded Blocks both RenderTypes work how they should, are you sure your EventHandler is called?

this should work, i will debug this local, which Forge version are you using

should work, you can also try cutoutMipped

you can take a look at the BucketItem for an example how to do it

Problem with Cyclops Core. Make sure you are using the latest version. If the Mod is already up to date, report this bug to the Mod author.

there is a debug log, if you using CurseForge you need to enable the debug log in the settings

yeah you could but you could also tell us if the event handler is called

post debug log

you can use the debug feature of your IDE or use a simple console print

you can save the Entity via Entity#save and load the Entity via EntityType.create

re you exactly talking about

show your code

yes, you should only send the data which are 100% necessary to come from clients, since the most logic should be done on server and the most stuff exists on server if you really need to send the BlockState through Network you can use FriendlyByteBuf#writeWithCodec, but i would recommend you to avoid this

you can get the Level from the ServerPlayer which you can get from the NetworkEvent.Context via NetworkEvent.Context#getSender

this is the latest log, please post debug log if your on CurseForge you need to enable the debug log in the settings

It could lead problems (as you have already noticed)

send a network message to the server, and handle there your code (action of the button) you can read more about it here

do not put DeferredRegister and RegistryObject in separate classes

post debug log, also use a paste site like https://gist.github.com/ to upload the file and stop formatting the file it's unreadable

post debug log from server and client

you mean in the Client screen? if yes you can not do this, blocks must place on server also do not handle logic on the client, the client is not your friend do not trust him

you can use Flat Directory Repositories, it's is also explained here: https://forge.gemwire.uk/wiki/Dependencies
