Im trying to render a non - rectangular sprite(bmp file) for a UI, I edited the image in photoshop and extracted the section I wanted. The problem is the image is rendered in a rectangle with white as the bg colour. how do I just render the section I want?

In Photoshop add an alpha layer and define the section you want to be 'invisible' i.e. not white, save the image in a format that supports alpha (I like png!). Then you have to enable texture alpha in your render states. Badda bing!

Kind regards,
