So in Max my texture works and in Meshlab my texture works, but once i upload my model to shapeways the texture is either wrong or isn't viewable. I have my model in .WRL format and my texture is baked into the model and in the proper directory and zipped with the WRL.
Open the wrl in word pad (or equivalent), look for the texture filename and check that it is just the filename without any drive/directory path. Also check that the texture file is of a supported image type (jpg, png or gif).
