Hi,

I try to create an Image out of a ByteBuffer. I can't use the TextureManager direct because the Texture Format is ".ACE" (Microsoft Train Simulator Texture).
I managed to read out the Infos in a ByteBuffer and I tested it directly in OpenGL. It works there so i assume that the ByteBuffer is set up correctly.
But now I like to do the same thing in JME. The first attempt ended in a white Texture and the following to. So I decided to try with a very simple ByteBuffer. Here is the code:

ACETexture ace = new ACETexture();
            ACELoader.loadACE(ace, file);
           
            ByteBuffer buf = BufferUtils.createByteBuffer(ace.width*ace.height*3);

            for(int j=0; j<ace.width*ace.height; j++)
            {
               buf.put((byte) 255);
               buf.put((byte) 0);
               buf.put((byte) 0);
            }
           
            Image img;
            img = new Image(Format.RGB16, ace.width, ace.height, buf);
            img.setData(ace.imageData);
           
            Texture tex = new Texture2D();
            tex.setMinificationFilter(Texture.MinificationFilter.BilinearNoMipMaps);
            tex.setMagnificationFilter(Texture.MagnificationFilter.Bilinear);
            tex.setImage(img);
           
            textures_jme.add(tex);


But when I do it like this, the result is a white plane to. Can anyone tell me, what I'm doing wrong?

Regards
David
