Hi, I used the Senran Kagura bms script over at aluigi's site on PS4 GinTama Rumble's .cat files and it dropped 1 .tmd model file and 2 .gnf files which contained the textures. Then I tried to use RTB's TMD importer 3ds max script from The VG Resource, but it only imported the skeleton and crashed at the mesh part. RTB said he will update the script for the game, but since he has other scripts to worry about, I figured someone here might help. http://www.mediafire.com/file/c1e9hehyb73jc9v/gintoki_model_samples.zip/file
this is a sample of Gintoki's body without the head because it is in other file, it also has the textures to check the UVs. There are two types of models H and L, maybe High and Low polygon, I realy wouldn't know, some models vary in 12 bytes and others are completely different.
Here's the TMDImporter https://mega.nz/#!ulpnmaJS!ffrdVu0T81lKBKR3FVkFO4K3jYPi5jtwd8Ac8hYL6FM
