We have discussed how to implement multitexturing support, and it turns out to be pretty hard to do without causing minor performance penalties for single-textured geometry. To be realistic, I do not think you will se it happen until the next major release of PLIB (but I promise to try and push it the best I can). There is another option, but only if you have a pressing need. You may subclass ssgSimpleState and add support for the secondary texture yourself. The problem is that you CANNOT use this new state in parallell with the original. ALL states must be of the new kind (including ssgContext::currentState!). We are using such an approach and it works because all geometry is loaded by a special version of the ASE loader, but there are certainly other ways to assure this. I cannot recommend this route. What I can do is to provide you with some source code, but be sure to understand the problems first. To summarize, you have two options: (1) wait until SSG supports multiple textures, or (2) do it the hard way. /Marten _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
