%%%Hi
when i render this scene (attached ) the curve-object (spiral) doesn't deform ( no animation ) like in the open gl viewport.
At the beginning, i suspected a problem of cache-baking but whatever the cache settings are, nothing happens...
Is it a bug, a limitation or did-i miss something ?

Big big congrats to all the team for your wonderfull work with blender !

Thank you

%%%just: with bi renderer, it works... seems to be a problem with cycles...%%%

%%%That was an issue with resetting point cache when duplicating objects. Cycles is duplicating Curves and converts them to Meshes when rendering, that's why curve with softbody wasn't deformed on render.

Made a patch which duplicates pointcache when duplicating objects, so now rendering happens correct.

There's one change in behavior tho -- if you'll Shift-D object with softbody, object will stay "unmoved" when you'll be moving it after duplicate and will only became undeformed after finishing transform. Before this patch object will became undeformed from the very beginning of Shift-D. Not sure if it's really big issue -- when you'll simply try move object with softbody it'll behave in exactly the same way.

@brecht, would be cool if you check whether such change seems safe for you. Otherwise i can make it duplicate softbody for Cycles needs only.%%%

%%%Commited with some modifications to preserve Shift-D behavior change. Rendering should work fine in rev50924.

Thanks for the report, closing now.%%%
