Hi, I'm trying to do a multipass effect, which uses only one shared shader program among all passes, but between passes the uniforms need to be updated.
The way I found to do this was to create n statesets, and n times the same uniforms, one per sate. This is a bit awkward, since I think I should be able to share the uniforms, and just update them once per pass in a callback. The problem is that as far as the source tells me, the update traversal is done before all the passes, as something like: event(); update(); //update all nodes/statesets/uniforms cull(); draw(); //draw all nodes/statesets So, there's no way that I can update an shared uniform, if it needs to be updated between passes? Thank you!
