I am trying to model a turret with two cannons attached(R18.057). The cannons are in Symmetry and, to make them rotate in a realistic Fashion, i have added a Motor, Connector and two Ridged Bodys. The set up is working in my Viewport. That is when i view the Animation the cannons are rotating. Now i tried to render the Animation out, but in the final render the Canons are no longer rotating. After quite some Exploration i found out that, if i disable the Symmetry-Object, with the same Settings and Dynamics attached as before, and render, the Motor/Dynamics/Roation will work in the final render aswell.
So, why is it that the Symmetry-Object hinders the Dynamics from actually Rendering? No matter the render engine. My Project and Render Settings match (at least i think so.. ). I have cleared and backed the Cache(s) of the Dynamics Tags.
I could just convert the Symmetry to Geometry, but that would suck. So i hoped there is a work around to this Problem. Mybe the issue has been solved in later versions of cinema?
