Texture transition

Recommended Posts

Hey people !

I'm looking for a way to smoothly transition from one texture to another, not like a gradient but rather like fading from one to the other over a time interval. I would also like to use the fixed pipeline. Should I use use blending, render one texture first and then render the other on top using some particular blend func? I haven't figured out how to use those with a fine precision value yet.

Thanks in advance !

Blending yes, but not necessarily on the render target. Have a look at [url="http://www.opengl.org/wiki/Texture_Combiners"]texture combiners[/url].

Interesting... Although when I try out the "Blend tex0 and tex1 based on a blending factor you supply", all my polygons turn out mono-colored and the lighting is gone. Did I mess up or miss some render state change?
