If another net message is already started and hasn't been sent yet, it will be discarded.⤶ <warning>Each net message has a length limit of 65,533 bytes (approximately 64 KiB) and your net message will error and fail to send if it is larger than this. ⤶ The net library has an internal buffer that sent messages are added to that is capable of holding roughly 256 kb at a time. Trying to send more will lead to the client being kicked because of a buffer overflow. <page text="More information on net library limits can be found here.">Networking_Usage#netlimits</page>⤶ The message name must be pooled with <page>util.AddNetworkString</page> beforehand!
