How do I add a tank to Single Player?

[andoodle]

Excuse me, everyone.

I have another question regarding adding vehicles to single player. In the past, I managed to code the M3 Stuart light tank from either BattleGroup42 or Forgotten Hope (that is, the vehicle folder, the standardMesh, and the textures, though I do not know if I added the sound) into my personal mod, and I replaced the M4 Sherman with it on Wake Island, since I believe that the M4 Sherman tanks were not used in the Battle of Wake Island in terms of history (I added the M3 Stuart tank to my mod for my personal use only). Unfortunately, when I started the map via my personal mod, I saw that parts of the bottom of the tank were stuck to the ground, and it rocked to and fro like a boat (that is, to the left and to the right). What am I doing wrong? I would like to know. Thanks.

If it was from Forgotten Hope, you need to change all of the material IDs to vanilla BF1942 IDs. I believe Forgotten Hope (and maybe BattleGroup) uses their own material IDs.

if it was rocking, you probably forgot the tank engine. look a bit more. you also have to change the material IDs of the mesh, because when I added the tiger 2 from the FH mod, it took damage wrong. It still has some issues, the AI can one-shot it from the front somehow, and I haven't been able to replicate it...
