I'm glad to bring an aplication that people find useful, thanks for all comments . At the moment I'm little busy but I promise work in more functions and improvements taking in count the recomendations.
Some people have problems for export their models so This time I wrote a tutorial for how export the obj models using autodesk maya. I Hope will help you
1. We make sure of the model do not excess the 20,000 tris, as we can see the number of tris is 4382 , so we won't have problem.
2. It's important combine all elements in one piece of polygons, (if you have just one don't worry about this step) . In this example we have two pieces: Mesh1 and Mesh2.
3.We select them and go to "combine tool" (red square) or select in the Menu-Mesh-Combine , the pieces will merge in one mesh.
4.After that its recommendable clean the modification so we delete the history of the mesh, ( it's like the Modifers in 3DMax) . For that we select in the menu "Edit- Delet All by Type-History" and "Edit- Delet All by Type-Non Deformer History"
5.In this case, we don't have texture, we assign a Lambert material in the HyperShade ("Window-Rendering Editor-Hypershade") Selecting the mesh and Right Click to the Lambert1 material and then selecting Assing the material to Selection. (NOTE: for using textures you will have to eliminate the spaces in the name of your jpg files and re-assign them in the same material, if your jpg files doens't have space you won't have problems , i will post that with more details in this week.) .
That's it! we have ready our Model to show it in the android tablet!
6.We need to export it in a OBJ model, for that we make sure that the plugin is enabled, we go to the Menu-Settings/Preferences-plugin Manager , look for the option of OBJexport and select loader and auto Load.
7.Export and Enjoy!
If you have another problem, just make me know .
