Unfortunately that's impossible without converting OpenGFX to NewGRF (it's in plain GRF format now). While probably none of the OpenGFX developers (including me) is interested in doing that, you're free to do so yourself. OpenGFX is GPL after all.maartena wrote:It would just be nice to use both graphics (original where opengfx does not yet has a sprite) at the same time, until all sprites are done.
From a reliable source I can tell that monorail and maglev engines are about to be included rather soon. Same goes (hopefully) for the PBS signals.
