Support / Few textures were applied and few not.
« on: March 18, 2015, 08:13:19 pm »
Hi
I tried to load a .3ds file into android by using our jpct-ae. i read the texture names from the file by using
String[] names_textures=Loader.readTextureNames3DS(mActivity.getResources().openRawResource(R.raw.house));
the above code returned me the list of texture files. i gave the same names while loading texture files but few of the textures only applied to the model object, rest of the textures were not. would you please tell me the reason why? Below is the my code.
