Hello, I''m making a 2d sprite library using OpenGl. I have a texture that contains multiple sprites. I display each sprite by drawing a textured quad and setting texture coordinates in a way only the part of the texture I want to be displayed will be drawn. This works fine but there''s one problem: due to texture filtering I get parts of the texture that are around my sprite blurred to the border of my sprite. For example if I have a texture that contains a white and a blue rect and I display only the blue part of it, the border of my quad on screen gets a bit lighter because of the texture filtering. How can I disable this ? I would like filtering to be still enabled but not at the edges of my quads. thanks in advandce http://www.turtlegame.de.vu- my 2D Platformer.

Either make each texture for each tile, and use GL_CLAMP_TO_EDGE as your S and T texture wrap mode, or make your own borders between tiles which match the edge (note that this will only work well if you''re not using mipmapping).
