   OpenGL ES: Render portion of a texture
  Im just wondering how can you render a portion of a texture, basically for 2D animation, so render start at 50,50 to 120,120. Ive tried using glTexSubImage2D but it doesn't seem to work. I can't find anything mentioning how to do this.   
  Yes, in fact, I'm pretty sure you can. Just manipulate the UV coordinates. The range, for UV coordinates, is [0,1], therefore you must use the dimensions of your texture and derive the size of a pixel by doing: 1.0 / DimX and 1.0 / DimY. Those are the respective offsets that you will need to use if you plan to move to any given (X,Y) in pixel space.   ;  Yeh im trying to hardcode some values now to do that, getting some weird results lol   ;  Fixed it now, thanks.
