Blender models not merging properly?

[SirSquidly]

So, I've been trying to merge two models together in blender, with the intent of them both sharing all their properties and textures and any everything you normally expect with combining.

 

Although, when I export the model to a .nif, I notice that the NiTriStrips are still separate, even though they are definitely combined in Blender.

 

Some much needed help would be amazing, and I will be in your eternal debt to anyone who can help me out here!

If they have different textures, they can't be merged. Blender will split them when it exports the meshes to nif format.

 

Sometimes, even if they have the same textures, Blender will still separate them. Off the top of my head, I don't know everything that has to be true in order for Blender to truly combine the meshes.

 

Is there some reason you need them to be combined? The nif format intentionally supports multiple meshes inside a single nif.

I think you need to remove any duplicate vertices along the seam where you are trying to join the meshes together, merge the vertices so there are seamless connections between the faces where you are joining and you'll also need to delete one or more of the UV maps so there is only one and not multiple. That is the only way I can think of two avoid a texture seam which I assume is what your trying to avoid?

I'm intentionally trying to make two models share a single mesh so they use the exact same set texture. I need it so in the geck, a texture can be changed on one of them, and affect both of them at the same time. Like attacking a spike to a bottle, then changing the bottle texture in the geck to affect both at once.
