Hi Robert (hope you follow this thread), Any clue what is going on? The sample code is with this scenario: texture0: some 2d image texture1: cubemap generated on the fly (prerender)
the mixing of these does not work and generates an error in draw. Up in this discussion is the example code which is osgprerendercubemap with some mods Nick http://www.linkedin.com/in/tnick Sent from Hermosa Beach, California, United States On Mon, Jan 25, 2010 at 2:21 PM, Wojciech Lewandowski <[email protected] > wrote: > I also made a test on Radeon 5890 64 bit Vista.
