FYI, I use 3DS Max 2015.
This is the original model. Note the smoothing errors. I will do like to find a way how to deal with those smoothing errors as well.
The model was initially a .dae file. I first imported the .dae file with default settings and then I exported the .dae as an .smd using wallworm exporter. Then, when I imported the exported .smd using wallworm .smd importer, it ends up looking like this in the picture.
So I have attempted to import this model into 3DS Max, but upon import, the imported model is messed up in some parts and I am not too sure why.
