Ugh - after two days of tinkering, three times of deleting everything and going back to step 1 to make sure I didn't miss anything, I finally managed to figure out where my problem is. (Thanks to the new preview feature in SimPE!! Nice work! Thanks, Thanks, Thanks!).

My problem appears to be in the Mesh Tool? Or maybe not.

Here's what I've got...

I get all the way up to step 33 (Open the mesh tool).

I load my edited OBJ file. Works fine. When I click "File->3D View" my modified mesh appears.

I load my "orgiginalGMDC.5gd". This file is the one I just extracted from my MESH_MyName.package in my downloads folder. Things say that they are fine and I save the file as "myNewGMDC.simpe".

Now, back in SimPE, I "replace" the GMDC file with "myNewGMDC", commit, and save - but when I preview it in SimPE - I see the old mesh and not the new one.

So, my error seems to be in how I'm working with the MeshTool.

Summary:

Modified Object is loaded (and appears properly in the 3D View from mesh tool).

Original GMDC is loaded in mesh tool and saved as a new GMDC.

Load that new GMDC in SimPE and it's still the old mesh showing.

For the life of me, I can't figure out how this is even possible....

Any help at all would be greatly appreciated.
