I took a break from 3DCrafter to do some effects.
Shift-Control-G now starts the DC Generator, with sound and exhaust effects. You can hear the whine of the turbine spinning up followed by a constant whine.
Shift-Control-C starts a pulsating steam jet coming from the drain cock of the Cross Compressor, accompanied by the sound of the steam jets. Hit Shift-Control-C again and it closes the cocks but leaves a whispy steam leak coming from the high-pressure steam side, and the sound quietens down.
Next, I'll do the bell effects, wth sound and animation.
I also improved the sound of the whistle. Now it really does sound like the real thing.
