Dragon Quest VII 3DS Model Texture/Material Issue!

[pkmntrainerelio]

I seem to come across a pretty big issue with the Dragon Quest VII models after being exported as .dae files and when opened in programs other than SPICA. The facial textures and materials (for the eyes and mouth) disappear. But in SPICA, all textures and models appear. The texture/material visibility issue was also a problem in Ohana3DS, but I extracted the .lz file with FEAT (Fire Emblem Archive Tool) and opened the extracted file in Spica. When opened in Blender, it only shows three textures and three materials (not the missing facial materials), same goes for PMX editor when the models are exported as .pmx from Blender.

Help would be really appreciated.
