Ethereal Orb textures:
 - Base: assets/theendupdate/textures/entity/ethereal_orb.png
 - Emissive overlay (charged): assets/theendupdate/textures/entity/ethereal_orb_emissive.png

The emissive overlay should be authored similar to glow squid emissive, containing only the glowing parts (the yellow bulb), with transparent rest. 32x32 matches current model UVs.

ETHEREAL ORB ENTITY TEXTURE REQUIREMENTS:

The ethereal orb entity needs a texture file at:
