Texture for sphere can not be renderred on Simulator

Hello,

I currently have problem with texture for sphere on Simulator.
Using Blender 2.48a, I create an "earth":
-Use UVShere
-Add Material
-Add Texture which is a flat earth image from NASA.

I can see the appearance of texture on Sphere when viewing object with Texture. Checking the earth.sio2 file, it contains the flat earth image, the Material, the Object. But when I used tutorial02 sample code to render this sphere on simulator, it displays the earth with black/white grids only. The texture can not be rendered.

I added these code to tutorial02 for binding resources:
sio2ResourceBindAllImages( sio2->_SIO2resource );
sio2ResourceBindAllMaterials( sio2->_SIO2resource );

-Blender Version: 2.48a
-SIO2 SDK Version: 1.35

Could anyone please help me?

Thanks,
Alex

This is the blender file and the image which I used: earth.zip

Thanks,

Can't download sorry... but:


1. Did you add some UV to the sphere.

2. Does the sphere map is a pow of 2 below 1024x1024?

Hi SiO2,

I dont know much 'bout Blender.So I need to work more with Blender for UV. I used 2048x1024 image.

I changed to IcoSphere with 2048x1024 image and it works now . It's so cool with a beginner!

Thanks,
Alex

Your texture have to be max: 1024x1024 to work properly on the device...
