I think you solved my issue by explaining the "createSpawnPackage" method. The bullets are rendered correctly. I still need to fix the registry you mentioned but it still seems to work. The registration should be part of the "pre-init" hook which is the "setup" method in the examplemod delivered with forge, right? Can I mark this thread as solved and give you some credits for helping me?

Sure, sorry since I do inherit from the ArrowRenderer I do get the arrow object form without any texture. This is something. Is there any documentation for the render method and how the vertex are used in minecraft?

I think I fixed the second issue like so @Override public IPacket<?> createSpawnPacket() { return NetworkHooks.getEntitySpawningPacket(this); } Now I do get an black arrow shaped thing which is already visible, this is a good start! The first point I cannot find a documentation I do understand. I did read multiple times through the following part https://mcforge.readthedocs.io/en/latest/concepts/registries/ but still don't get it

Hey there, I know there are a lot of threads for custom entity rendering with different solutions like the following: https://forums.minecraftforge.net/topic/84158-1152-solved-custom-arrow-entity-not-rendering/ I tried a lot of things and I cannot get the arrow/bullet into a state where it is rendererd ...

The bullet entity itself is not visible while it is flying to the target and I do not know why. I think there is somthing wrong with either the ResourceLocation or how I do bind the renderer to the item. Edit: pasted whole weapon code instead of just the spawn part. I did start yesterday with modding so feel free to correct things which could be done better Thank you in advance for helping
