Hi EgonOlsen

       Finally i am able to set the textures to my model by removing below code.

        world.setAmbientLight(20, 20, 20);
        sun.setIntensity(250, 250, 250);

           
             Thank you so much for you support and response.   

Hi EgonOlsen

             thanks alot for your patience and quick response. I didn't increase any ambient colors in my code. i am just fallowing the same code which i attached to our previous conversation (i.e March 18, 2015, 08:13:19 pm). If you don't mine would you please share me the source code what you have tried?

Hi EgonOlsen

     I attached the screen shot of my model. in the image, black area should be green color gross but it is showing as black color.

Hi EgonOlsen

        Please find the attached log.zip file.

Hi EgonOlsen

Thanks for the reply. I removed cube.calcTextureWrapSpherical(); But it's not working for me. would you please provide me any sample source code which contains .3ds file displaying with multiple textures?

I tried to display the below .3ds model.

http://www.shareaec.com/v/22436/browse/5/3D-Model/Stone-Front-Home


Only few of the textures are applying to this model few were not like gross & top.

Thanks in advance.

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.

Thanks a lot for quick reply.

My exact problem is, I downloaded one .3ds model object from net. i found multiple textures in that folder i.e 003.jpg,009.jpg,119.jpg... .

My question is what are the names i need to give while loading textures.

ex:  TextureManager.getInstance().addTexture(
            "003.jpg",
            new Texture(
                  BitmapHelper.rescale(BitmapHelper.convert(mActivity
                        .getResources().getDrawable(R.drawable.c003)),
                        128, 128)));

         is the above is correct or is there any chance to know the given texture names of .3ds file? Please help me. i have been stuck from past 1 week.

Hi

   I tried to load a house.3ds file using JPCT-AE. i have multiple texture files to add. Below is the way how i am attaching the textures.


house= load3DSModel(
            mActivity.getResources().openRawResource(R.raw.cottagen131214),
            0.5f);

      TextureManager.getInstance().addTexture(
            "003.jpg",
            new Texture(
                  BitmapHelper.rescale(BitmapHelper.convert(mActivity
                        .getResources().getDrawable(R.drawable.c003)),
                        128, 128)));

      TextureManager.getInstance().addTexture(
            "009.jpg",
            new Texture(
                  BitmapHelper.rescale(BitmapHelper.convert(mActivity
                        .getResources().getDrawable(R.drawable.c009)),
                        128, 128)));

      TextureManager.getInstance().addTexture(
            "119.jpg",
            new Texture(
                  BitmapHelper.rescale(BitmapHelper.convert(mActivity
                        .getResources().getDrawable(R.drawable.c119)),
                        128, 128)));

      TextureManager.getInstance().addTexture(
            "221 roof gray.jpg",
            new Texture(BitmapHelper.rescale(BitmapHelper.convert(mActivity
                  .getResources().getDrawable(R.drawable.c221roofgray)),
                  128, 128)));

      TextureManager.getInstance().addTexture(
            "Doski113.jpg",
            new Texture(BitmapHelper.rescale(BitmapHelper.convert(mActivity
                  .getResources().getDrawable(R.drawable.doski113)), 128,
                  128)));

      TextureManager.getInstance().addTexture(
            "old3.jpg",
            new Texture(
                  BitmapHelper.rescale(BitmapHelper.convert(mActivity
                        .getResources().getDrawable(R.drawable.old3)),
                        128, 128)));

      TextureManager.getInstance().addTexture(
            "OLDMETAL.jpg",
            new Texture(BitmapHelper.rescale(BitmapHelper.convert(mActivity
                  .getResources().getDrawable(R.drawable.oldmetal)), 128,
                  128)));

      TextureManager.getInstance().addTexture(
            "stone_paving_01.jpg",
            new Texture(BitmapHelper.rescale(BitmapHelper
                  .convert(mActivity.getResources().getDrawable(
                        R.drawable.stone_paving_01)), 128, 128)));

It seems not working. Please help me to apply the multiple textures to my .3ds model. thanks in advance.
