Hi Carsten, a second quick notice beside the problems mentioned some minutes ago: I looked into the MDW code in more detail and found out that each FBOViewport will be rendered on each cluster server. That may make sense most cases but in our case that means that each server will have to render at least 2x6 FBOViewports which is not the best way I can imagine. Do you think there is a better way? For example to create some kind of special viewport that does FBO rendering and texture mixing locally on each server? Could you give some advise?
Thanks, Michael > Hi Carsten, > > this is strange.
