yeah, it works just fine, all the way back to Bryce 1.0 The resume render feature has always been a part of bryce. When I originally got Bryce 1.0, I was running on a Mac '030 at 33MHz... most of my renders took over 10 hours to complete, so I got very familiar with this feature :-) When you use the Render To Disk or Render to Animation features, resume render doesn't work... because Bryce isn't smart enough to figure out where the partially completed files are. It only works when you just use the regular Render command. As for rendering an animation.... you can easily render it in chunks by selecting a "working area"... that little green bar that fills up part of the animation area. So select just a partial working area, and in "Render Animation", select "render working area" instead of "entire animation". If you want to interrupt a current render, just interrupt it and click "stop"... delete the last BMP frame, and render from that frame forward later. Details of the "working area" are in your manual, under the Animation section... or maybe it's under the Rendering section, I don't remember. There isn't any way to resume a "Render to Disk..." command, to my knowledge. This poses a bit of a problem, since render to disk is the only way to render really really high resolution files, which are the ones that take forever anyway.
