I'm currently working on a model of a colonial era cannon. I'm wanting to add a normal map from a high poly model to the low poly model however whenever I try I always get some distorted results. So far I haven't figure out why I have looked all over the internet but so far haven't found any similar results. I made sure to add smoothing groups to my low poly model. I also tried the bake with and without a cage and had the same results. I feel like i'm missing a step but am not quite sure what that may be.
Here is a link the the image and blend files for what I have so far.
Unfortunately I'm limited to two links per post so I can't post them directly here.
