Yesterday, i put my animation to render, it went fine. But one thing that bothers me is: What is the Render and Preview? I actually discovered that the Render is something like the quality, so i keep it on 128 because it is fast and the quality is great for me. But what is Preview? And what should i keep it on? Any help would be appreciated.
I use the CUDA with GPU Compute rendering (cycles). I'm new to Blender so i may seem silly.
The preview setting determines the quality of the rendering in your viewport, when you hit Shift+Z. Since it's always refreshing and recalculating the image whenever you change the view or a material setting or else, you will probably want it to have far lower settings than your render settings.
