So I'm trying to make an alt helmet (and eventually an accompanying skin) for Harrow, however I've hit a wall pretty early in that nothing I make will import into the Tennogen View. The content files from the help page insert fine, but my models just don't show up, without a pop-up or anything. I am creating my models in blender, which I've heard works for making tennogen content, and I am exporting them as an obj.

My best guess is it's something to do with the export settings on blender, though as you may tell, I am not very experienced in this stuff.

Blender's export settings are as follows:
Forward: [-Z Forward]
Up: [Y Up]
[] Selection Only
[] Animation
[] Apply Modifiers
[] Use Modifiers Render Settings
[] Include Edges
[] Smooth Groups
[] Bitflag Smooth Groups
[] Write Normals
[] Include UVs
[] Write Materials
[] Triangulate Faces
[] Write Nurbs
[] Polygroups
[] Objects as OBJ Objects
[] Objects as OBJ Groups
[] Material Groups
[] Keep Vertex Order
Scale <1.00>
Path Mod [Auto}

I have tried many combinations of these export settings, including trying to get as close as possible to the Tennogen OBJ export settings for Max.

Please could someone help me, if it is not something to do with the export settings, is there some other way, like any free programs I could import my creations into and then export again into an obj file that works with Tennogen?

Thank you for your help
