Weird Triangles & Gloss on Converted Hair

Hi. The screenshots aren't showing up. Upload your screenshot to somewhere like imgur.com, right-click the image and choose "open image in new tab." Copy the URL then click the button with the photograph icon in this message box and enter the URL. Your screenshot will be embedded in your post.

Do you have access to Milkshape? You can reorder the groups that way. If you search for "milkshape" in the comments in this tutorial there are some instructions there. You can also look at this and this and hopefully glean something. I don't know very much about this, sorry; all I can do is give general instructions and provide some links to look at.

I can tell you that you'll need this CAS map and you'll need to UV map your hair in the hair section.

And the normals are flipped. Your mesh is inside-out. It's easier to see flipped normals if you enable backface culling. Press N to open the side panel. Ignore the right side of this screenshot.



Now, you can see how your mesh is inside out. Select your mesh, edit mode, press T to open the side panel, press A to select your entire mesh, then press the recalculate button.



Edit: forgot to add that if you're making an alpha hair I think you need six mesh groups instead of the normal three. Download an alpha hair from Sims Resource (or somewhere), export the blend, and study how it's put together. That should give you an idea of what you need to do. And take a look at this thread. It may help. 

I'm not sure where the shine is coming from. Your specular is black but it looks like you made the bump map blank? That's kind of a cheatey way of doing things that I don't recommend. A lot of new people don't want to bother with a bump map because they think it's hard. It's not hard to make and can really improve the quality of your mesh.

Hi.
The shine is coming from the empty normal map. Never make the normal blank for items that are using the simglass shader.
You need to replace it with the "properly" empty normal map.
Just export a normal map from any other hair mesh as dds, open the file, sample the background color and flood rgb channel with it. Then switch to the alpha channel and do the same.
Also, you have has no uv_1 and vertex paint, it will not morph with the head.
