thank you, I got it. very low gradewrong. I thought the L+B is the origion(actually the L+T). so my overlay is out of my screen

I want to show some pictures above my screen(for example,arrow/up/down/left),so I use overlay.
I wrote like this:

Texture arrowdown=new Texture(BitmapHelper.rescale(LoaderMana.LoadBitMap(R.drawable.arrowdown),128,128));
TextureManager.getInstance().addTexture("arrowdown",  arrowdown);
Overlay down = new Overlay(world, 128, 128, 256, 0, "arrowdown");

But the arrow did't show,Is there any problems?or is there any other ways?

sorry for late reply, thank you EgonOlsen, I will try

ok,I know, the 3d object I export from 3dx is empty...

I want to create a terrain using jpct-ae. and the terrain may contain high mountai, river and so on.
any idea about how to realize it with jpct-ae?
I'm very very very wonder how "Topic: Thinking about some RPG..Android version" did it? (http://www.jpct.net/forum2/index.php/topic,2471.0.html)

Maybe something wrong not like you said...
I moved the camera and changed the scale of my character, but it didn't work.
Besides, I added "Log.e("startLoadModel","startLoadModel");"  and "Log.e("completeLoadModel","completeLoadModel");" around the "thing = LoaderMana.loadModel("walktest.3DS", scale);". but the logcat only show "startLoadModel".
The last sentence of logcat show abou jpct is "Name in hierarchy found $$$DUMMY"which I could't understand.
why?Can anyone help me?

thank you,I will try....

I encountered some troubles when I  loaded a 3ds file.
The file I used has been upload to "https://rapidshare.com/files/3587059474/Chap05_05_Final.max". you can click "download" to down it.(which you must have the 3dmax software)
The file is a animation course, it contains a lot of key frames of a character.
I export one of the frame to a 3ds file use "3dmax".
But when I load the 3ds model. The screen is black, the code I used I think is correct because it displayed correct when I loaded a cube which is 3ds format
Can anyone help me?
(the 3ds file I used is "https://rapidshare.com/files/492188704/walk.3DS", you can click download to get it).

I used the SkyBox to create the sky:
1:The picture I used is 512*512, include five pictures(front, back, right, left, top)
2:The SkyBox size is 1024.(because I see "The box will extend in all directions by half the size when viewed from the center");
but my sky become deformed around these edges of pictures. why...?

And there is another question...
I want to make a sence, and I will create the sence in my 3dmax,and then,export each of the model as 3ds file in the sence to jpct-ae,and then every model is located in the right place,is that right...?

thanks..

first....my english is poor...
my question is..
