UI: Move Material Properties to Post-Processing Section

[Rakadeja]

---

Summary

Currently, the Base Material and Bevel Material properties are located at the top of the "Live Tweaking" section. However, their functionality is directly tied to the "Post-Processing" options, specifically the Multi-Material toggle. This can be confusing for users.

To improve clarity and user experience, these properties should be moved into the "Post-Processing Options" sub-panel.

Current Behavior

The material slots are grouped with general geometry settings.

Expected Behavior

The material slots are located alongside the Multi-Material checkbox, making their relationship clear.

Suspected Code Regions

This is a UI-only change. The implementation is located entirely within the draw() method of the BF2M_PT_Panel class in ui.py.

# ui.py -> class BF2M_PT_Panel -> draw()

# ...
box = layout.box()
box.label(text="2. Live Tweaking", icon='SETTINGS')

# Literally the easiest 'fix' ever.
box.prop(props, "material_base")
box.prop(props, "material_bevel")
# ------------------------------------

box.label(text="Text Geometry")
# ...
# ... into this section ...
box.label(text="Post-Processing Options")
post_proc_box = box.box()

col = post_proc_box.column()
# (The toggles are here)
