Thanks MrWonko, this solved my issue and the export is working fine now. However another issue has sparked. Screenshots of issue: Error in ModView Noesis dosn't recognise arm - Hierarchy error? Model in blender, nothing seemingly wrong with it? Blender Hierarchy Now, I'm pretty sure that the hierarchy is practically the same as the original model's (Arcann) in the attempt to prevent any errors like this, yet I still receive faults in both Noesis and Modview which I believe to be because of the arms as these are the main things i have edited. Additionally I used a mirror modifier on the left (original) arm to make an exact copy for the right side which may be the reason why one arm won't show? The one arm being for some reason the original left arm not showing. - I tested this in two different ways, the mirrored objects are attached to each other so i had to separate them, after separating each piece of the arm accordingly I'm really not sure what's wrong and from all the other posts i've seen regarding this issue, I still after following everything i've found cannot get this to work. Again sorry for the troubles
