help with SMT3's .AB .MB .TB formats

[ZeroFX]

I need help with getting textures and reimporting for these formats, i googled and stumbled on some zenhax threads but neither of them talked about these formats in specific, only .PB, a script called "Atlus_PB" by tge (im downloading the 3ds student version 2018 because im getting errors on 2021), it can be used for loading the model (pc.mb) into 3ds max and getting the textures out of the pc.tb but im clueless on how to reimport said textures into pc.tb.

Any help its appreciated, thanks in advance.

Here's all the resources I have on exporting and reimporting custom models in Nocturne's formats, I haven't attempted it myself yet but others seem to have had some success.

DDS3ModelConverter by TGE (it's a commandline tool so you'll have to use it in the command prompt, parameters below)

DDS3ModelConverter Commands

Export PB model to OBJ/DAE + textures

Code: Select all

--input "player_a.PB" --output "player_a.DAE" 

Export PB model to OBJ/DAE, textures + animations

Code: Select all

--input "player_a.PB" --output "player_a.DAE" --assimp-output-pb-anim

Replace PB model with OBJ/DAE/FBX

Code: Select all

--input "player_a_replacement.fbx" --output "player_a_replacement.PB" --pb-replace-input "player_a.PB"

If you want to automatically scale the textures if your replacement model, use

Code: Select all

--tmx-scale 1.0

with whatever scale you prefer eg. 0.5.

Replace motion (animation) in PB model with DAE/FBX

Code: Select all

--input "player_a_m_0_replacement.fbx" --output "player_a_replacement.PB" --assimp-input-anim --pb-replace-input "player_a.PB" --pb-replace-motion-index 0

Blend weights are very buggy, so you can use this while importing to disable weights:

Code: Select all

--mb-weighted-mesh-type 1

Alternatively you can tweak

Code: Select all

--mb-mesh-weight-limit <integer>

Default is 4. Lower values seem to get better results, but can make the importer crash.

You can also tweak:

Code: Select all

--mb-batch-vertex-limit <integer>

Default is 24. Messing with it might be useful.

Replace field LB with DAE/FBX

Code: Select all

--input "field_replacement.fbx" --output "field_replacement.LB" --f1-lb-replace-input "f001_001.LB"

That's wonderful, thanks!

hey ZeroFX did you have any luck with this? i was trying to edit demi fiends eye texture and i actually got to do it, but when i try to convert my fbx into a pb dds3modelconverter says "too many weights per face" and i don't really know how to fix this

If you’re using 3dsmax, try setting the weight limit (under Advanced in the Skin modifier of each mesh) to 4 or less, should prevent anything from getting assigned too many weights
