[REQ] Import "smoothing groups" that keeps mesh connected

I've read up on smoothing group issues both in these forums and on various Blender forums. I am convinced that it should be possible to have this plugin import a mesh that stays connected *and* keeps the proper smoothing.

I was introduced to a method that does exactly that by TFA many months ago. I have since tested the method on several models and got someone else to run his own tests. The method works.

The method is described here: https://sites.google.com/site/zeqmacaw/tutorials/importing-smoothing-groups-into-blender

Would you implement an automated form of this in the plugin? Note that there might be a need to warn the user that it could take longer to import higher-poly models.

The author of this topic has marked a post as the answer to their question.

I've found a much better fix for this and shipped it in 2.10.

I too support this; ive tested several models and this is one of the best things that can help improve the importer.

Excellent, that modifier will indeed solve the problem!

This is now available from GitHub.[github.com] Give it a try and tell me if you hit any issues. :)

Awesome! Thanks, I'll give it some testing as soon as I can.

Did some testing on 3 different models. One worked, but the other 2 did not.

This 7z has the 3 SMD files I used in the tests: https://drive.google.com/open?id=1nOqs-B-ZwWPfzDxAwm7H3jcPMicyztcn

I put "fails" or "works" at the start of the file names.

I was surprised how fast they imported. I am hopeful that the two failed ones indicate a simple oversight on something.

The two meshes fail because they contain duplicated faces which are killed by Remove Doubles, and that causes the data transfer modifier to fail. Unfortunately there is no way to have blender remove merge just the vertices unless I loop over everything in Python and do it manually.

Removing doubles can sometimes be a bad thing when working with these models. Especially in the objects where VTAs are applied. Hmmm.. I've downloaded the master, but haven't had a chance to work with it yet (so I shouldn't really be responding yet), but I thought I'd throw that out there.
