I know this is a pretty niche issue but if you have the time it's basically a where the game sees it as an item or something and displays it as a little item in your hand rather than as a full sized tool

This issue only happens with vivecraft, but from what i've seen the vivecraft devs have tried to fix it and it looks like it's probably a bug on the mod's side.

Going to close this as there is probably nothing we can do. If there is a Vivecraft issue, feel free to link it here. Going to guess they don't properly work with the forge model hooks.

First, deleting issue format doesnt help anything.
Second, pretty sure vivecraft uses Optifine, which is incompatible for the most part with Tcon

Vivecraft? Never heard of it. They are probably misusing the model format, a vanilla feature that Forge also extends. This is not Tinker fault, this is someone remaking the renderer.

Tell the vivecraft devs to look into the Forge model system a bit more, notably the perspective mapper.

Leave this open until the issue is resolved.
