Может потому игрока НЕ СУЩЕСТВУЕТ в главном меню?

+
иными словами, this.mc.thePlayer = null
Чтобы отрендерить игрока нужна моделька ModelBiped, а скин грузить либо char.png, либо по никнейму с сайта моджангов.

 

[deleted.user]

Либо костыль - предварительно коннектиться к лобби\серверу, получать оттуда игрока, рендерить его и вот. Или создавать фейк игрока, сохранив его какие либо слоты, что б в меню нормально отрисовать что на нем одето было и так далее. Костыли, но тоже вариант. Смотря что тебе в итоге нужно. Могу подкинуть код кое-какой конечно, но не буду, т.к. это не так и сложно

 

[BlesseNtumble]

Создать мир в меню, как это сделано в bspkrs lib
