I'm rendering this scene in cycles (blender) on GPU with GTX 780 3GB In preview mode it takes about 2mins to render 2000 samples. In final render mode it takes about 40 seconds But i need to rotate scene and render it from different view. After rotation the model, render time has been increased to 20 times (to 20 mins per a frame) But in preview mode it still renders for 2 mins
what's the problem? Problem appears only after rotating the object. If i moove the camera and NOT rotate the object it renders for 2 mins. But I need to rotate the object and not moove camera.
