I fixed a few things and now it should be able to texture battle models without having to fix the id's outside the program.
PCreator v0.85bI'll explain how to texture your Powerblade according to cloud's file names.
First of all we need to put the number of textures that the whole model will use into the hierarchy (rtaa) file. We have two for cloud's head his eye and mouth (rtac, rtad), then the textures that the power blade uses: rtae - Handle.bmp, rtaf - Base.bmp, rtag - Blade.bmp, rtah - Materia.bmp. In total we have six so first set it to a battle model then go to Open Battle HRC... under the file menu. Open cloud's hierarchy (rtaa) file and set the number of battle textures to 6.
Then add the model groups in a logical order and then load all the texture files. After that you need to set the texture ID for each group.
Handle = 2 (the Handle starts at 2 because cloud's eyes and mouth are using Id's 0 and 1)
Base = 3
Blade = 4
Materia = 5
Select Texture File(s) under the Options menu so it writes all the texture files, then save the model over the buster sword (rtck). Rename the textures to the following:
Handle = rtae
Base = rtaf
Blade = rtag
Materia = rtah
Then just put all the changed files in the battle.lgp, make sure to put in rtaa because it was changed from having 2 textures to 6.
