Simplify Blender shaders to a simple diffuse texture for export (written for GLideN64-Scene-Ripper)
# Fixes shaders from GLideN64-Scene-Ripper for OBJ/etc export.
# Instructions: select objects you want to fix, then run this
# script from the Text editor.
# Tested with Blender 3.6.
import bpy
# Whether to connect the diffuse texture's alpha to the
# Principled Alpha socket in the simplified material.

Notes on how IQM 2 animations work
Notes on how IQM 2 animations work:
(see http://sauerbraten.org/iqm/iqm.txt)
There is just one global animation strip for the whole file. Each iqmanim is
defined by picking out one subrange of frames from this global strip.
Every joint has one iqmpose. Every iqmpose has ten channels for the ten TRS
properties (Tx Ty Tz Qx Qy Qz Qw Sx Sy Sz). Every channel maps a frame
number to the value of that TRS property at that frame. A channel can be
either constant or variable.
