Noesis rip exporter help

Hi everyone, 

I'm trying Ninja Ripper for the first time and was able to rip quite a few nice sharks, fishes & even marine mammals and they look awesome as shown in Noesis Preview

However, when exporting to dae, fbx or obj, the model screws up. Even direct export to the same folder with the settings as shown above, the model immediately screws up in Noesis preview as shown below.

It is either transparent or have their texture screwed up. Additionally, I've noticed the number of materials decreased from 5 to 1 but not sure if it matters. It could not export perfectly for other sharks model too. 

Any help to get the model to export perfectly to Blender would be greatly appreciated. 

Btw if you're interested in the models (fishes/sharks) and could help to upload & share them can PM me (once I sort out this problem at least)
