Don't display sydney texture file

[leekihyun]

hi.
i'm working with opengl es 2.0 on irrlicht android.
can display sydney md2 mesh file. but do not display sydney texture.
just white sydney is displayed.
why ? please let me know.
thanks.

IIRC, the texture is not power-of-two. So might be a problem with texture modes not properly supported or set. Try to rescale the texture.

hi. hybrid.
Thanks for your answer.
Sydney mesh is displayed. but not display texture.
just Sydney is running without texture -_-;;
when i used opengl es 1.0, everything is fine. texture displayed.
But in this case, opengl es 2.0, not working. WHY ??
maybe i think shader is problem. What's the problem ? ^^;
(irrlichtandroid 1.7.0-beta, opengl es 2.0)

this is my sample code :

stringc sydneyFilename = "/Irrlicht/sydney.md2";
mesh = smgr->getMesh( (gSdCardPath+sydneyFilename).c_str() );
if (!mesh)
{
device->drop();
__android_log_print(ANDROID_LOG_INFO, "Irrlicht", "cannot getMesh");
return;
}
nodeSydney = smgr->addAnimatedMeshSceneNode( mesh );

if (nodeSydney)
{
nodeSydney->setMaterialFlag(EMF_LIGHTING, false);
nodeSydney->setMD2Animation(scene::EMAT_RUN);
stringc sydneyTextureFilename = "/Irrlicht/sydney.bmp";
nodeSydney->setMaterialTexture( 0, driver->getTexture((gSdCardPath+sydneyTextureFilename).c_str()) );
__android_log_print(ANDROID_LOG_INFO, "Irrlicht", "add texture");
}

@leekihyun: Did you try what Hybrid said and rescaled the texture to have a power of two width (like 128, 256, 512 or 1024 pixels)?

[leekihyun]

@CuteAlien : I'm not sure the power of two width ?
Sydney's size is 308x193. You mean that rescaled to 128x128 or 256x256 ?
I did it. but not display texture.
If I send my sample code to you, can you check what's the problem ?

[CuteAlien]

Sorry, I can't check (I'm not doing Android development, I don't even have a mobile phone actually).
But yes - rescaling to those numbers was what I meant (although only width matters, height doesn't really matter but if nothing shows that's not the problem).

I hope someone else can help you.

@CuteAlien : ^^ thanks for your kind.
I will check more.

I was having the same problem with android. I was adding the models in the main loop and not the draw loop. I fixed it by adding the models in the draw loop.
