SOLVED
Okay so I have my DAE file out of Maya with a JPG for texture information, which has already had me jumping through a series of hoops to get this far.
My polypaint importer plugin won't work in Maya 2014 and I can't export DAE files in 2015, both come up with errors or just crash. So I sent my file out of zbrush and UV mapped it to convert the vertex color to a texture in maya 2015 then sent the OBJ to 2014 and exported as a DAE, the textures show up in both versions. Wasn't sure how else to get the vertex color out and I couldn't find the options for the other filetypes. But it seemed like it was all working fine, but when I upload to shapeways it says there's no color.
The JPG and DAE have the exact same name, and are zipped together, they're under the file-size limit and polycounts, and the texture is 2048*2048.
