Mid point between levels on subsurf modifier I'm trying to make a holographic representation of one of the models I made. However, I had the problem of the final render and the preview being drastically different.


 Bottom right is preview and top right is render 
I later found that the problem was to do with the subsurf modifier I had on the block and the blades. At this point I had it set to adaptive on the render. So I figured I had to change that to the level I had it on the preview.

Again there was a problem. They were not the same so I thought I had to lower it to fix. However, I could only get bad results on the blades.

So my question is how can I make the final render wireframe look like it does in the preview?
As Timaroberts said, the preview and render settings need to match for it to be the same. This means that it will not work if you are using the adaptive subsurf setting on the newer versions of blender.

Occasionally you will need to reload blender before the viewport preview matches the final render when the preview and final are the same.
