sorry dont have time now to review the whole thread. You could check the svn history for fixes since 1.2.
one suggest is rather than finding all the lightpoints in the model to attach a uniform, simply attach a single uniform to the root of your model; that uniform state should be inherited down into all child nodes. Since uniforms and glEnables are entirely separate, there should be no interference. At least that would work for OSG 2.x, cant recall for 1.2 -- mew On Thu, Apr 3, 2008 at 10:12 AM, Monteleone, Nathan <[EMAIL PROTECTED]> wrote: > Hi Mike, > > Thanks for the info!
